Of the half-dozen Viagra-type drugs on the market now, Viagra itself may still have “the greatest efficacy, but also has the highest rate of overall [side] effects.” It’s still a pretty safe drug. Some guy swallowed 65 at a time in hopes he’d go out with a bang, but it didn’t work. The most commonly-observed acute side effects include headache, flushing, stomach upset, runny nose, and vision abnormalities. But now that it’s been around for a decade, some chronic effects may be cropping up—for example, glaucoma, “one of the leading causes of blindness,” caused by degeneration of the optic nerve. Up to nearly ten times the odds of glaucoma among those using Viagra long-term.

But, it’s cancer that has the medical community rethinking the safety of these kinds of drugs. Men with advanced prostate cancer often have to get a radical prostatectomy, a surgery that can leave them both incontinent and impotent, which can reduce their quality of life. Therefore, a treatment concept called “penile rehabilitation” was introduced, where drugs like Viagra are given to counteract the side effects of the surgery. But, there have been studies like this, that found Viagra could decrease natural killer cell activity, and natural killer cells are our first line of immune defense against cancer. Now, this was a study on women for something else, but it did raise concerns about giving Viagra to those battling prostate cancer.

In terms of getting prostate cancer in the first place, men treated with Viagra-type drugs “tended to have less of a chance of being diagnosed with prostate cancer.” Yeah, but that may just be because they’re ejaculating more. “[H]igh[er] ejaculation frequency may be associated with a lower risk of…prostate cancer.” It’s interesting the reason they think why. “Frequent ejaculations may decrease the…concentration [within the prostate gland itself] of xenobiotic compounds [like hormone-disrupting chemicals] and…carcinogens.” Anything we eat can end up in our prostate. Drink a cup of coffee, and you end up with caffeinated semen ten hours later. Smoke a cigarette, and the nicotine ends up in the same place. Or eat fish, and end up with one-seventh the healthy sperm count, perhaps because there’s like three times the concentration of PCBs. But, anyway, you don’t know for sure about Viagra, until you put it to the test.

Nearly 5,000 prostate cancer survivors were followed, and those taking Viagra-type drugs did seem to have a little bump in their risk of the cancer coming back. But subsequent studies failed to find such an association. What moved me to make this video is the “unexpected connection” between Viagra and melanoma skin cancer.

“If treated early, melanoma can be cured by [cutting it out], but due to its proclivity to metastasize, in about 20% of patients, it progresses to an aggressive invasive disease” that can kill in a matter of months. And, part of the way it does this is through a gene mutation in the cancer that induces melanoma cell invasion by downregulating an enzyme called phosphodiesterase 5. Does that word look familiar? That’s what Viagra does. Viagra works because it’s a phosphodiesterase-5 inhibitor. So, Viagra may have the same effect in terms of promoting melanoma growth. You don’t know, though, until you put it to the test.

And, Viagra use was associated with an 84% “increased risk of subsequent melanoma” diagnosis. And, you put all the studies together, and the association remains significant. So, here we have this class of drugs “found in medicine cabinets” across the country, and the FDA does its best trying “to ensure the safety and efficacy of such drugs.” But, you can’t “always anticipate the molecular consequences of inhibiting major cellular pathways.”

There is, however, an alternative explanation. Maybe users of Viagra are just naked more, thus giving their partners the opportunity to notice some suspicious mole or something, as only about one in three melanomas are “discovered by the patients themselves.”

      1. Sorry, that was for a study about eggs from Australia which came out last week and had a piece on it by science daily. I didn’t realise there was already a new one on science daily. I think this is a different study.

    1. Maybe it’s because people who don’t eat eggs everyday in China are poorer and have a lower educational level, not the more health oriented people like in the West: ‘Compared with non-consumers (those who never or rarely consumed eggs), daily consumers were more likely to have a higher level of education and household income, to have a new affluence dietary pattern, and to take multivitamin supplementation.’

      1. Yeah, there are so many factors that could have influenced the outcome. Terrible study, but I’m sure people will argue it.

      2. Peoples will do literally anything to justify egg consumption.
        Know of one now elderly fitness and diet guru locally widely published and a author of many books, who is a advocate for egg consumption.
        He revealed possibly inadvertently that he has now due to complications go off his statin meds…..that he has been on for 20 years.
        Coupled that with a history of prostate cancer and this from a guy who exercises faithfully, like Jack LaLane faithfully his world revolves around fitness.
        And with a few exceptions such as eggs has a really healthy diet.

    2. This was an observational study and threfore subject to confounding variables ie the people who ate eggs also had other characteristics which affected their risk of disease.

      As M85 points out, the Chinese people who ate more eggs were wealthier, better educated and took a multivitamin. They also had a dietary pattern which tended to differ from people who didn’t eat eggs.

    3. Would someone please explain how…..At the start of the study period, 13.1% of participants reported daily consumption (usual amount 0.76 egg/day) and 9.1% reported never or very rare consumption (usual amount 0.29 egg/day) of eggs

      From the abstract and mentioned in this article .76 eggs per day is considered daily consumption and .29 per day is none or very rare consumption???

  1. All of these -not so modest- conclusions are based on just two unvalidated questions the researchers asked a bunch of people; “how much eggs do you eat?” at the beginning of the study and; “how much eggs do you eat?” at the end of the study.

    The results are better suited for psychologists and Chinese culture experts than it is for anybody to draw whatever conclusion about the health effects of consumption of a certain type of food.

  2. This study is scary. I’m a woman who takes 60mg of generic Viagra everyday. I’m in an experimental study through a huge research hospital because of a rare eye disease that has affected my central vision. I’ve been in it for over a year with the hope of preserving vision long enough until the stem cell treatment or other treatment is available to me. They said other than headaches, there should be no side affects. Possible melanoma is huge. I have to reconsider. Wow.

  3. What about if i use viagra as a fertility ivf measure by inserting the pill(down there) to provide more blood flow to my uterus to prepare for ivf as my dr prescribed.

      1. Thank you Paz. I was thinking about acupuncture due to joint issues, but since an ovarian cancer diagnois, I no longer have ovaries, but do have my uterus just for fertilty, that’s why medication can only help.

    1. Viagra and flu with mice however.
      Would be real nice if the flu shot was good for something at this point. The most hazard population the elderly find most years only a 40 percent or so protection. And that figure is based upon those who seek medical help to remove the symptoms which probably adds at least another ten or more percent who do not.

      Would take by most estimates about a billion to fund a universal flu shot. But why should they endeavor that when so much is made with auxiliary treatments such as Tamiflu and over the counter meds?
      About the clearest situation of a for profit drug industry not providing what is needed as profit does not instigate it that I know of.
      Flu is the leading actual cause of death for the elderly complicated with other present medical conditions.
      By some study 25% of those admitted for flu to a hospital die from it.

  4. These studies scare me too. I have prostate cancer and although I had radiation rather than prostatectomy, I was one of the ones prescribed Viagra for penile therapy. I have not had melanoma, but I have had basal cell carcinoma. I now have been taking Cialis about once a week in an effort to help keep things working. Plese help!

      1. Thank you. I switched to a plant-based diet in early 2016 shortly after my diagnosis, thanks in great part to the advocacy of Dr. Greger. I believe it will always be a work in progress, but I think I do fairly well. I also started brisk walking about 3 miles most days. I have gone into a few periods of relative inactivity since then, but I tend to get back into the groove in fairly short order. So I probably need to keep this news about PDE5 inhibitors and cancer risk in perspective. I can’t change the past, of course. Meantime, it is probably wise for me and others to forego the possible prophylactic benefits of PDE5 inhibitors and stop using them. 85% (or something like that) increased risk of melanoma is quite a lot.

        1. Scott, I’m assuming that the 85% increased risk of melanoma is increased relative risk — so the question is, what is the absolute risk to begin with?

          “Overall, the lifetime risk of getting melanoma is about 2.6% (1 in 38) for whites, 0.1% (1 in 1,000) for blacks, and 0.58% (1 in 172) for Hispanics.” (https://www.cancer.org/cancer/melanoma-skin-cancer/about/key-statistics.html) So, if you are white, the increased risk is 85% of 2.6%, or an increase in absolute risk of about 2.2%, to about 4.8%. To me, 2.2% doesn’t seem like a large increase in risk.

          It also sounds as though you are doing what you can to improve your odds, which is all that any of us can do. My husband was also diagnosed with prostate cancer, now 13 years ago (before we met), and his diet since he met me 11 years ago — and started eating my vegetarian (at that time) cooking — has improved considerably. Plus, he slowly lost first 30 pounds (which he wanted to do), than an additional 15 after we moved to whole foods plant based eating (and he’s pleased about that, too). He had brachytherapy, and was not prescribed any drugs prophylactically — which don’t seem necessary. (He’s now 75.)

          That said, life is short, and I believe it should be enjoyed to the fullest extent possible. We all have to balance the benefits of any treatment with the risks, and make the best decision we can for ourselves. I wish you all the best.

        2. This whole thing leads to an idea they didn’t discuss in the video: If a small deposit of every kind of food a man eats ends up in the prostate, could that help explain some cases of prostate cancer, and why certain foods and supplements help protect against it? The research says that having a deficiency of zinc can cause it; certain herbs can prevent it; and eating an anti-inflammatory diet, including anti-inflammatory spices like turmeric, can prevent it. Is that why vegetarians have a much lower incidence of prostate cancer? Because their prostates are not contaminated with the inflammatory molecules from things like red meat, dairy products, eggs, sugar, unhealthy fats, etc.?

          1. I think you’re onto something, Bob. However, it seems to get tricky when supplementing with certain synthetic vitamin/mineral supplements and even certain natural extract supplements too. Selenium is one that may be more harmful than helpful when taken in supplement form. Calcium may be another.
            Beta carotene and folate (or folic acid) seem to fit the bill as well. This helps explain why Dr. Gregor generally supports getting nutrients from whole foods rather than supplements or food fortifications. There are of course exceptions—like B12.

          2. Hi I’m a RN health support volunteer. Thanks for your great question. A lot of the initial research we had on prostate cancer came from epidemiological studies when it was noted that populations like Japan that had a very plant centered diet had extremely low rates of prostate cancer compared to populations like the US who had a very processed and animal protein heavy diet. I think we’re still trying to identify the exact mechanisms. It can be hard to do controlled studies on cancer because you have to find a group that is willing to forego treatment. Although this has probably been done more with prostate cancer than other cancers. Dr. Ornish took one of the first steps in that direction:
            https://www.ornish.com/wp-content/uploads/Intensive_Lifestyle_Changes_and_Prostate_Cancer.pdf

            Here is some other information Dr. Greger has done:
            https://nutritionfacts.org/video/prostate-cancer-survival-the-av-ratio/

            Hope that helps,
            NurseKelly

            1. Thank you, Nurse Kelly, for the response!

              The links in your reply led me to a bunch of awesome Dr. Greger videos explaining the link between our diet and cancer, particularly prostate cancer. A lot of great info, for anyone wanting to stay free of, or reverse, cancer.

              On the same page as the video “Prostate Cancer Survival: the A/V Ratio” are links to a bunch of other great videos on that subject. I learned some things I didn’t know:

              Worst things for the prostate: Eggs, Poultry, followed by Meat and Dairy.

              The more animal foods you eat vs. plant foods, the higher your risk. They’ve known for a long time about the link between Meat, Milk, & Eggs and prostate cancer.

              A vegan diet appears to literally reprogram gene expression within the prostate! This possibly has something to do with the fact that a small amount of all foods consumed by a man leave a deposit in the prostate. Of course, this is most likely true of all organs in the body – for instance, vegetarians have a different makeup of enzyme species in the intestines compared to meat-eaters.

              Eggs, Milk, Red Meat, Poultry, Shellfish & Fish are our major sources of Choline, which in the intestines produces TMAO, which causes the various indicators of heart disease. Red Meat contains Carnitine, which also creates TMAO. Choline-containing foods also cause & spread cancer. Researchers can predict your risk of prostate cancer by how many eggs you eat per week! And in prostate cancer patients, they can predict how soon your cancer will spread to other organs and kill you by HOW MANY EGGS YOU EAT PER WEEK. All cancer cells contain a large amount of Choline!

              A plant-based diet, with moderate exercise, seems to be the best protocol for killing cancer cells. The foods that most promote cancer growth are Meat, Eggs, Dairy, & things made with Flour.

              Lignans kill cancer cells. Flax seeds contain 75 to 800 times more Lignans than any other food. To fully absorb the benefits of flax seeds, though, you have to grind them into a powder & put them in juice, coconut milk, coconut yogurt, on your buckwheat cereal, whatever. Though the seeds are very small, when you eat them whole, a lot of them pass through still intact, so you’re not getting the lignans, omega-3, 6, & 9 fatty acids, or other nutrients that flax seeds are so good at providing.

              Thank you for all the new information, Kelly.

              1. Thank you for your valuable information and insight, Bob and Kelly. It is a breath of fresh air to read them after reading in a prostate cancer forum a post sardonically titled “Vegan Shmegan.” The author had the audacity to call nutritionfacts.org a random site. What was more troubling was that so many fellow prostate cancer patients cheered him on for citing a recent study that did not show a relationship between diet and prostate cancer progression.

                1. Scott,

                  Don’t let those with a negative attitude, or who refuse to see truth, bother you. Just wish them well, and focus on your own journey. And it is a blessed journey , even if it doesn’t seem so right now. With an ever-improving healthy diet, some physical activity each day, and a mind & heart that work as one to see the beauty and perfection in everything, looking for the good things in the world instead of the bad, every cell of your physical body will regain its balance & perfect alignment. All unwanted bodily conditions will slowly dissipate, until they no longer exist.

                  Always keep in your mind the things God is telling us through Abraham:

                  “How do you get from where you are to where you want to be?

                  Look in the direction of, speak in the direction of, think & daydream in the direction of where you want to be; and never look over your shoulder at where you have come from.”

                  “You could have ten illnesses today, and tomorrow have no evidence of any of them. Your body has the ability to replenish itself that fast. But most of you don’t have the ability to change your THOUGHTS fast enough to make that happen. And that is the only thing stopping you!”

                  “Some may say, ‘If our thoughts are so powerful, and create everything in our experience, then why aren’t people growing new limbs?’ Because none of you BELIEVE you can.”

  5. This is a leap, but given this information, should melanoma patients avoid pomegranate and other food sources of phosphodiesterase until further study?

  6. Very interesting video. But I’m curious why there wasn’t control for sun exposure. Doesn’t melanoma skin cancer need sun to form?

    1. I don’t believe sun exposure is the only cause for melanoma or necessary to get it. Hopefully you get a better response, but this is my basic understanding.

      1. Yes, as Ron in New Mejico pointed out there are two types… one from the sun and another from dark moles.

        Would have been helpful if the video had made this distinction.

  7. Are many of the screenshots of the studies blurry? I’ve not noticed this in other videos, and I wanted to make sure it’s not my vision!

  8. I’m curious how my drug eluting stent is affecting me? I know they use viagra or some similar drug on that. I didn’t have a choice since I was unconscious and wouldn’t have known the difference when I had my MI anyway.

  9. There was no mention of dosage in the video. Is there any safe amount you can take? Is taking a 100mg pill once a week just as bad for melanoma risk?

  10. Test fire and go blind, use viagra and go blind. What’s a guy to do? Life is turning out to be a cruel joke.
    I guess blind is better than blind with cancer. Better go talk to my wife & see whether she’s in the mood.

      1. Ejaculation of either or any kind helps in the prevention of prostate cancer it is thought.
        I went a couple of times with no ejaculation for a month or so and then self indulged and found the stuff that came out after was really ugly. Not white and with consistency but sort of off white and runny. Looked spoiled actually like spoiled milk.

        Ugh….I figure if you don’t have sex at least once a week self pleasure is probably mandatory.
        Our culture is getting better but really this is a subject not discussed much. Jerry Seinfelds comedy show had one episode on this which probably did more to normalize it than anything prior to my opinion.

        1. “I went a couple of times with no ejaculation for a month or so and then self indulged and found the stuff that came out after was really ugly. Not white and with consistency but sort of off white and runny. Looked spoiled actually like spoiled milk.”

          Ron, I read a long time ago that semen is resorbed after a relatively short time if not ejaculated. Maybe you just caught it at the end of its “use by”
          date. ‘-)

  11. Thank you Dr. G, for your deadpan comment regarding the would-be suicide who consumed 65 hits of Viagra in order to “go out with a bang.” I was hoping for a double-blind test to examine the issue of frequency of ejaculation, but was curious how the placebo would be handled. Results of such a test would give mothers the opportunity to add cancer to their imprecations of blindness and hirsute palms as cautionary warnings to curb adolescent self-gratification. Not that teenage boys would really care.

    1. Peoples will injest the oddest things with that aim. I actually had experience with one person who had taken a inordinate amount of vit C tablets and another who had taken many packs of artificial sugar ..strangely enough I guess as precaution in the event something else was taken, both were inspired by means to vacate stomach content.
      But no that was seemingly it….

      And of course further treatment was required to determine cause, and additional psychological therapy necessity.
      I guess it is just a desperate attempt to take anything at hand in the event it works. Not well thought however.

    1. Never saw the purpose of Viagra personally..I mean if you don’t feel like it a whole lot of work would then become unnecessary to be performed work…

      If married I suppose it then would be a required duty of some sort perhaps.But that reminds me of responsibility and would seemingly take the fun out of it.

      In any event……I would much prefer if I did not have that tendency….such a waste of time and effort ;) Guess I am in that a bit not human. Not that I would put a hug or this or that in the same category. But you don’t need Viagra for those type things.

      Like a elephant who tied to a stake as a baby now still thinks the stake can hold him there though he is now much stronger…why would one seek a tether a stake to hold oneself to at thing…?

      Few will agree with me I suppose. How beautiful is that thing they may say…I see grunting groaning sweating pulling pushing perhaps a scream or two……not so pretty by my read….. a silent mind it produces but only for a minute or so at best….. I could force a silence that lasts far longer.

  12. This caused me to look up Melanoma and I am going to be using Amazon Prime to watch the video: Healing Cancer from the Inside Out.

    The Melanoma Website quoted that video and said the results they had were:

    Stage II Malignant Melanoma

    39% alive after 5 years (typical diet and conventional treatments)

    82% alive after 5 years (plant based diet with no conventional treatments)

    —————————————————————————–
    Stage IV Malignant Melanoma

    6% alive after 4 years (Conventional treatment and typical diet)

    39% alive after 4 years (adopted a 100% plant based diet)

    ——————————————————————————-
    Stage I & II Malignant Melanoma

    That adapted a 100% plant based diet had a 100% survival rate after 5 years

    ——————————————————————————–
    Stage III Malignant Melanoma

    That adapted a plant based diet had a 71% survival rate after 5 years.

    I haven’t watched it yet to verify it, but my car is broken down tonight, so it is a good night for a video.

    1. I always thought of skin cancer being of two types. The first commonly is all sun exposure and is relatively easily treated. And the second is more a inherent tendency to formation such as a abberant mole or some such which leads to cancer. The second kind being far harder to treat.

      The second could be exasperated by sun exposure or other exposure but is not necessarily primary cause. the first is always sun exposure with a relative common progression from pre cancerous to cancer, removal is always the treatment. The second no it is always a spreading type of cancer….am I wrong in this impression….to lazy to look it up ;)

      In any event I think one study has shown the first has lesser chance of presentation if one imbibes caffine or coffee.

      1. Ron, one of the points the video made was that people are spending so much time indoors (and are low in Vitamin D to prove it, is my addition) and yet Skin Cancer is rising through the roof.

        1. He said that most of the people with Melanoma spend the most time indoors.

          (Maybe it is the lack of Vitamin D from sunlight instead of too much sun?)

          I don’t have the answer yet.

          The video keeps causing me to push pause and think.

    2. I am a third of the way through watching the video on Amazon Prime streaming and I don’t even know what to say.

      Thank you, Colin Campbell.

      It is full of things, which I heard a year ago, but this time it is out of the mouths of doctors like Colin Campbell and John McDougall and Gerson is still there.

      It is so frustrating that the Medical Community has all of these authoritative people who constantly come against that message.

      If you have Cancer, get on WFPB Organic Superfoods ASAP. No matter what.

      My only fear is wondering how we will know that the Organic foods are actually Organic, since according to Dr. Greger 11% aren’t really Organic?

      I don’t have time to garden, but I am going to have to learn.

      But do we also have to get the potting soil tested?

      1. I think one of the encouraging things was that they showed the pollution in Okinawa and said that pollution is only the cause of 5% of Cancers, because people with a healthy diet, who live in pollution don’t get it.

        They were also talking about that Japan has the highest rates of smoking and don’t have Lung Cancer like we do and that Americans have cut their smoking in half, but Lung Cancer has not been cut in half with it.

        T. Colin Campbell said that just from society having so many people give up smoking, that should have brought Cancer rates down and it didn’t. He said, “The numbers don’t square up.”

        It is a fascinating video, even for strange statistics like those.

        1. Deb just to mention…“They were also talking about that Japan has the highest rates of smoking and don’t have Lung Cancer like we do and that Americans have cut their smoking in half, but Lung Cancer has not been cut in half with it.
          A major risk factor as contributor to lung cancer is radon exposure. Soil type geology can tend a area to be productive of radon.
          Just to venture a guess but the Japanese open floor plan for housing and less solid obstruction from the outdoors on average compared to americans may tend to lower exposure to radon gas naturally emitting from soils into structures. They would still suffer emission but it would not concentrate but tend to dissipate.

          Our type construction favors concentration of the gas unless a barrier or ventilation of the soils before it reaches the structure is presented.
          It is unknown the exact amount of lung cancer produced in the US from radon gas but it may be appreciable. In the absence of smoking it is probably the leading cause of lung cancer by my read.

          Volcanic soils tend more to this production.

  13. Pehaps the adolescent self-gratification should be encouraged ………..

    “in a study of almost 32,000 men published in the journal of European Urology, researchers found high levels of sexual activity can reduce the risk of contracting prostate cancer by 33 per cent.

    The optimum number is 21 ejaculations per month.”

    http://www.news.com.au/lifestyle/health/health-problems/researchers-say-frequent-ejaculation-could-save-mens-lives/news-story/dedd2ce2cb85c9cf6ff67f24c455dbe5

    1. I agree. If I had a teenage son, I sure wouldn’t be laying any guilt trip on him for doing what comes naturally and is apparently also naturally good for him.

    2. Is there a mechanism given?

      It brings me back to Dr. Kellogg and the acne theory.

      Maybe he wasn’t a quack for looking at that link after all?

      Though I still wonder how they know whether it is a hormone leading more of them to that behavior versus the act itself?

      Or was it a controlled study?

      And I am not going to make a pun right now.

      Self-control.

      1. I have to say that it is the one study I have ever heard of where I could ask if the Control Group was a Self-Control Group?

        Or was that the other group?

      2. Okay, I am reaching the end of the Cancer video on Amazon and they talked about people being healed of Cancer by the Placebo effect and that there was a woman who had her hair fall out from Placebo Effect Chemotherapy.

        So, I go back to the self-stimulating study and I will borrow from the Cancer video hypothesizing why Placebo Effect can heal Cancer and they said, “Stress relief” lowering Cortisol.

        I think knowing how powerful Placebo Effect is, it makes me want to not discourage people who are in the middle of a good Placebo Effect.

        A rehab for the Stroke Community said that the biggest thing to watch for is the “No-See-bo” effect, where people tell you nothing will help and you give up and the person was right, nothing does.

        Don’t take my Placebo effect from me.

    3. Well……”the optimum number is 21 ejaculations per month.”

      That is just to high a number for me. Attainable certainly but think about it….You have to spend or I would have to spend at least ten or fifteen minutes getting in the mood and getting it on and all that…look at some pictures listen to some music whatever….you could I guess just quickly pull your pud but it would seem to miss a bit……so. And that is just preparation…you then have to find a place sit down lie down whatever in a quiet place without disturbing others and then you must shower or clean up in some form…..being then probably smelly.

      So put a pencil to it…you live how much longer but how much of your life is spent then doing that thing. Subtract one from the other and by my read doing that 21 times a month is a subtraction of around 5 hours.
      5 hours a month minimally possibly longer include a shower or such….. is a lot of time to subtract from life.
      I could think of about a thousand other things of more benefit to myself I could do with that five hours. Suppose I walked or jogged….. would that not be five hours of reduction then since cancer is inhibited in formation it seems of many kinds if we exercise?
      Or perhaps just doing a thing we enjoy, read a good book watch a good movie go dancing whatever….

      Nah no 21 for me.
      But my intention is not to live very long but to enjoy what there is while I am here.
      21 I would obsess it. Put it on a calendar perhaps mark them off..like work it would be quite dreary and dull ;(

      1. Aside the topic but perhaps relevant….coincidentally I live in a forest. And there are a couple who come up regularly to a spot near my property but more into the forest to yes….go about naked and have sex in a remote area far from a trail.

        My little dog came upon them today and gave them a bit of a startle. I was clearing brush for fire protection. He is in his fifties and presumedly takes Viagra. And this is at a altitude of 7200 feet and usually they participate in this in days of direct sun….I now know their car.
        He is also noticeably pale…..I try to avoid them but on occasion I can not.

        Curious the topic and all and the occurance. I don’t expect I will be talking to them as they strike me as a bit odd but reading this I did think……
        things at times seem unrelated and remote but usually they are not being connected in some form or other..:)

        Viagra skin cancer chance sex and all right at my door ..;) and now here same thing. Odd, Jung would have a field day with things of this sort.

        1. Ron, why do you presume that a man in his 50s takes Viagra? My first husband was 58 when our daughter was born, and my current husband is 75 and almost 11 years post-treatment for prostate cancer (brachytherapy) — and neither one took or takes Viagra. No need.

          ED (erectile dysfunction) is an early sign of CVD (cardiovascular disease) — the canary in the mine, if you will. If a man did need Viagra, it would make more sense for him to change his lifestyle, starting with diet and exercise

  14. I am still watching the Cancer video.

    The woman from the Living Food Institute (I think it was called that) has seen Parkinson’s and AIDS and all sorts of things reverse. A lot of the people in the show are doctors. When I did this research a year and a half ago, most of the people I encountered were chiropractors and lay people. It is a relief to find resources with doctors and researchers. It takes away the confusion.

    T. Colin Campbell’s animal protein at 20% causing Cancer in the presence of a Carcinogen and animal protein being down at 5% being low enough for Cancer to not grow even in the presence of a Carcinogen is what I am meditating and I was just thinking about Synchronicity myself, because a Keto person on YouTube brought up that study and put it down as being based on research on animals.

    I have people who have Cancer around me and it is so frustrating that there is so much misinformation and that Cancer doctors won’t consider WFPB.

    One of the men goes to chemotherapy tomorrow.

    I can’t get them to believe WFPB, because their doctors are the authority figures they believe. Painful.

    1. Yes, and it is even sadder that many of those in the medical community that are more inclined to defy convention would recommend a ketogenic diet over a whole foods, plant-based one.

      1. Scott,

        I watched What The Health today and all the people who are supposed to be protecting our health are ridiculously recommending the very foods which would kill us.

        Dr Greger and all these men are heroes.

        They are the David’s standing up to so many Goliaths that I find all of them brave and respect them so much.

        I am going to be praying for their protection.

        In What The Health they talked about the email between the egg industry people about whether they should take a hit man out on the egg replacement president.

        That is so disturbing and I don’t even know how they know they were only joking.

        1. You are right though that the doctors do tend to be open to Keto.

          This movement is organized and has good personalities.

          They just need someone who isn’t evolutionary oriented to get into the churches and a movement for the colleges and it could suddenly grow exponentially. I add in Senior Centers, because getting rid of pain in seniors could win people faster than anything else.

          They need Comicon characters and comic books and those always become movies. It has to be someone who understands comic super heroes.

          The Incredible Bulk fiber character would be hoe I would think, but I like stupidly obvious sense of humor.

          Dr Greger did a good Q&A or two or three today

      2. Dr. Greger, in a YouTube video (where he was being interviewed) stated that he doesn’t recommend any particular macronutrient ratio. High-fat is fine, he suggested, as long as it’s from whole plant foods.

        There’s also Dr. Thomas Lodi at “An Oasis of Healing” cancer treatment center that stated (in a YouTube video) they use a ketogenic diet for their cancer patients. But, it’s entirely plant-based, as Dr. Lodi is a whole-food plant-based vegan himself and that’s the diet they recommend. They do lots of green juices at the clinic, too.

        1. Walter,

          Thanks for the link. I will look at it.

          I am interested in WFPB Keto versus WFPB closer to the Starch Solution.

          The video didn’t seem to make it sound like people often need WFPB Keto to heal from most diseases, including Cancer.

          They emphasized “a moderately healthy plant based diet” or some wording like that. I am taking that to mean John McDougalls concept of whichever types of WFPB you will eat.

          Dr Barnard got amazing results for Diabetes with just low fat WFPB no white or wheat flour.

          John gets amazing results and people eat white potatoes and wheat bread.

          I am having more fun doing a learning about superfoods with Dr Greger process and it reminds me every day to eat healthy, so I am doing superfoods.

          Not sure about the whole Keto thing, because they usually use oils.

          I have conquered my hatred of blueberries this week.

          I found out I can put one green grape and one blueberry iny mouth at the same time and I can eat a whole cup of blueberries now.

          You have to understand everybody around me is dating the all meat all the time and extra oil version of Keto and their doctors are saying keep losing weight.

  15. Dr. Greger, Colleagues, and/or Knowledgeable Commentators:

    I’d appreciate your feedback on the following:

    Final Takedown of Anti-Fat, USDA, Vegan, Anti-Meat, Food Pyramid Research
    https://www.youtube.com/watch?v=KkDLIuStX_M

    “90% of nutritional research is wrong or grossly exaggerated. Learn from Dr. John Ioannidis, the world’s top meta-researcher.”

    Many thanks,

    Aaron

  16. In the end it is said Viagra is ‘put to the test’ with a prosective cohort study. Isn’t it true only multiple double-blind RCTs in humans can do this? As of this fact, I think it is still inconclusive.
    Also notice the following study I found which expects increased melanoma risk might be due to other reasons than just regular PDE5 inhibitors: https://www.empr.com/news/melanoma-risk-with-pde5-inhibitors-likely-due-to-sun-not-side-effect/article/503415/
