The management of stage T1c prostate cancer is identical to that of stage T2 prostate cancer. The treatment of a cancer detected by an elevated PSA level depends primarily on the age and health of the patient, on his preferences for treatment, and on the manner in which the physician presents the options. The distinction between PSA-detected tumors that are visible on ultrasound and PSA-detected tumors that are invisible on ultrasound is not clinically useful.
