Exercise linked with reduced prostate cancer risk in Caucasians but not African-Americans

Exercise linked with reduced prostate cancer risk in Caucasians but not African-Americans: A new study suggests that exercise may reduce Caucasian men's risk of developing prostate cancer. And among Caucasian men who do have prostate cancer, exercise may reduce their risk of having more serious forms of the disease. Unfortunately, the benefits do not seem to apply to African-American men.
