Family history can play a big part of your risk of prostate cancer. If your family has a history of prostate cancer, you may have a greater risk of developing it yourself. Having a close relative with prostate cancer can give you a 2-3 times larger chance of getting this disease. As of now, there is no specific gene responsible for the elevated risk of prostate cancer. As far as scientists can tell, the answers lie in multiple genes.
