Prostate cancer is the most common form of cancer in American men other than skin cancer. The American Cancer Society had estimated that about 185,000 new cases of prostate cancer would have been diagnosed by 2008 in the USA alone. Almost 30,000 men will die of the disease in 2008 alone in this country. It is the second leading cause of cancer death in men after lung cancer. While a man has a 15% chance of being diagnosed with prostate cancer during his lifetime, only 3% actually dies of the disease. The use of PSA as a screening tool has resulted in a far greater number of men being diagnosed with prostate cancer at the earliest stages. Thus, in the modern era, the vast majority of men live for a long time after diagnosis and treatment. This has translated into younger men being diagnosed with prostate cancer and long-term sexual function becoming an even bigger issue given these factors.
