Has anyone rooted the cause of such high rates of prostate cancer? Is this cancer happening regardless of location or diet?
Here are a few facts: There seems to be some connection between a high-fat, Western diet and developing prostate cancer. In the US, African-Americans have the highest incidence, with Asian-Americans the lowest. Studies show that there may be a genetic link and that the responsible gene is similar to the gene causing breast cancer in women. If a man's father or brother had prostate cancer, the odds are higher that he will develop it.
The big event, in terms of the early diagnosis and treatment of prostate cancer was the development of the PSA test in the mid-80s. More men are being diagnosed in their 50s and early 60s, without symptoms. By the time symptoms are present the cancer may have already spread.
Selenium appears to have a preventive effect on prostate cancer, as does soy. Regular vigorous exercise has a preventive effect, but hey, we already know that. Three helpful books I read were 'Prostate Cancer for Dummies' (Paul Lange), "Dr Peter Scardino's Prostate Book' and 'Dr Patrick Walsh's Guide to Surviving Prostate Cancer'. These books also have a lot of solid, medical information regarding the other prostate conditions, BPH and prostatitis.
