7 genetic risk factors found for prostate cancer

This article caught my attention because I just studied about health disparities among different races in my health diversity class. This article says that researchers have just "described seven genetic risk factors (DNA sequences present in some people but not others — bunched in a relatively small region of one of the human chromosomes, chromosome 8) that reliably predict one’s probability of developing prostate cancer". The research was propelled by the fact that the disease's greater prevalence among African American men hinted at a genetic basis. This is important for the obvious reason of earlier diagnosis and prevention, but also for research being done on why African American men are more likely to develop prostate cancer. Research found that African American men are twice as likely to die from prostate cancer, and nearly all of the risk factors were seen most frequently in blacks involved in the study. They go on to say that the cancer is not all genetic, there are also lifestyle and enviromental factors.
