why prostate cancer is more prevalent in blacks than whites?

Question

I have found that prostate cancer is predominate in blacks not because of their skin color,but relative to the physical wrok done as slaves.Most balcks are natural built with more muscle mass than whites and the prostate cancer rate can be traced to the deterioration of muscle mass over a period of time. Other factors include weight gain and the increase of the human life span with respect to sexuality. There is a relationship between sexual aggression and the loss of muscle mass and prostate cancer this also is demonstrated with people have sexual impotency problem having a low prostate cancer rate. Also people using steriods will have a high prostate cancer rate because of the relative decrease in muscle mass.

Answer 1

Interesting thoughts, but here are some more likely possibilities:

1) Simple genetics has a lot to do with prostate cancer. Regardless of race, you are more likely to have it if a close relative (father or brother) has it. This may explain nearly all ethnic variance in PCa.
2) Vitamin D deficiency has been suggested as a possible contributor. Internal production of vitamin D is corellated to melatonin.
3) Diet has a great deal to do with it. High fat diet, red meats, all have positive corellation.
4) Higher poverty rate, which implies less access to health care.
5) PCa isn't related to muscle mass or potency, but is related to testosterone level. I don't know of any studies on relative testosterone levels by race.

Answer 2

A lot of diseases are more prevalent in blacks. It is just the nature of things. Your theory is hogwash.
