Prostate cancer is the most common non-skin cancer and the second leading cause of cancer mortality among men in the United States. The incidence of prostate cancer has increased over the last years in part due to early detection programs including serum prostate-specific antigen (PSA) and transrectal ultrasonography.
Prostate cancer has no specific presenting symptoms and can be clinically silent. In some cases it may present with urinary obstruction similar to that seen in prostatic hyperplasia. The treatment of prostate cancer may vary depending on the stage of the tumor at the time of diagnosis.
