Skin Color’s Impact on Prostate Cancer
(Ivanhoe Newswire) –A new study found that exercise can actually reduce a man’s risk of prostate cancer, but only if they are white.
For the study, men about to go in for a prostate biopsy filled out a survey on how much exercise they do each week. Out of the 307 men who participated in the survey, 164 were white and 143 were black.
Caucasian participants who were found to be moderately or highly active were 53% less likely to have abnormal biopsy results suggesting prostate cancer. Furthermore, Caucasian patients who exercised regularly with biopsy results showing prostate cancer were 13% lower risk of having a high-grade form of the disease likely to spread and grow quickly.
On the other hand, African American participants who were moderately or highly active were no less likely to have prostate cancer than participants who lived a predominantly sedentary lifestyle. Degrees of regular exercise also had no effect on how aggressive the prostate cancer is.
The results are particularly unfortunate because the risk of prostate cancer is very high for African American men, but they could help to explain why this is so.
"These findings that African-American men may not benefit from exercise the way Caucasian men do could be a contributor to why African- American race is a risk factor for prostate cancer and aggressive prostate cancer,” researcher Lionel L. Bañez, M.D., from the Durham Veterans Affairs Medical Center was quoted as saying.
Although lifestyle changes such as exercising regularly may not improve their chances of avoiding the disease, it does emphasize African American men’s need to monitor any possible problems that could be prostate cancer.
