The Pros and Cons of Testing PSA Levels for Prostate Cancer
Given the clear harms and the small and uncertain benefits, most men would presumably decide to decline PSA testing if they knew all the facts, but that’s up to each man to decide.
Topic summary contributed by volunteer(s): Claire
The 2005 Ornish study indicated that the plant-based diet may be beneficial for reducing and reversing the occurrence of prostate cancer. Some specific foods that may be effective include flaxseed, cranberries, turmeric, and almond milk. The occurrence of prostate cancer may also decrease if the following items are restricted in the diet: the amino acid methionine, choline and cows’ milk. Benign prostatic hypertrophy and benign prostatic hyperplasia (BPH) may be less of a natural consequence of aging, and more indicative of eating an unhealthy diet and not exercising enough. The same kinds of healthy lifestyle interventions that have been shown to be effective at reducing the occurrence of prostate cancer are also helpful in keeping BPH in check.

Reducing the ratio of animal to plant protein in men’s diets may slow the progression of prostate cancer.
Methionine restriction—best achieved through a plant-based diet—may prove to have a major impact on patients with cancer because, unlike normal tissues, many human tumors require the amino acid methionine to grow.
