Sun Exposure and Prostate Issues

[Guest guest]

Hi folks:

This looks pretty interesting:

Particularly the following, some of which we already realize:

"Prostate cancer is the most commonly diagnosed cancer in the United States (Boring, Squires, Tong, & Montgomery, 1994)"

"Mortality rates vary greatly between countries. For example, rates in Japan are one fifteenth those in America, although rates among Japanese immigrants quadruple after migration to the United States (Haenszel & Kurihara, 1968) ........ with rates between countries varying 10-fold (Zaridze, Boyle, & Smans, 1984). However, autopsy studies have found that the prevalence of latent prostate cancer does not vary greatly between countries (Yatani, et al., 1982), suggesting that the variation in mortality may be caused by factors affecting tumor growth (Dhom, et al. 1983). "

"Frequent sun exposure among African American men was associated with a 40% reduction in the odds of abnormal PSA (OR = 0.59; 95% CI = 0.20-1.69). In contrast, among Caucasian men, a 68% reduction was observed."

Could it be that it is supplemental vitamin D that explains the results Al posted?
