Being susceptible to a particularly aggressive form of prostate cancer could be in your genes, according to this. Scientists have identified a genetic marker called 8q24 that ups your chances of getting prostate cancer or having a family member that will by a significant amount. The presence of the marker can be determined by a blood test, and those with it will have to ensure they're more careful about getting screened for cancer. Furthermore, African American men are more likely to be carriers than those of European ancestry. I've had several family members who've been diagnosed with prostate cancer, and it's scary stuff, boys! Get yourself checked out for the sake of yourself and your loved ones.
