Prostate cancer is the most common non-skin cancer among men in the United States.
We initially studied brothers where at least one has prostate cancer in order to investigate the potential relation between genetic factors and their disease. More recently, we have launched a new study of men diagnosed with more advanced prostate cancer. We are collecting blood from these men, as well as basic information on their health and habits. From the blood we will get DNA, and then use this information look at those genes that plausibly could lead to prostate cancer, based on current scientific evidence. The information from this study will help provide men with additional knowledge about their risk of prostate cancer and, if they are already diseased, how genes might influence their response to treatment.
