I know that prostate cancer is one of the most common kinds of cancer, so I’d like to find out more about it. What are the risk factors for prostate cancer? I know that a family history of any cancer is usually a risk factor, and that nutrition can sometimes play a role in reducing the risk of some cancers, is this the case in prostate cancer as well? I have heard that problems with urination and ejaculation can be prostate cancer symptoms, including frequent urination and blood in the urine. Are there other symptoms that I might notice if I am in the early stages of prostate cancer?
