Prostate cancer is the second most commonly diagnosed cancer in men (after skin cancer) and the second leading cause of cancer death in American men. Diagnosis of prostate cancer and adequate staging play a fundamental role for clinical and patient care.
Benign prostatic hyperplasia, or BPH, is a noncancerous enlargement of the prostate gland. It is the most common benign tumor found in men. As the prostate gets bigger, it may constrict or partially block the urethra (the tube that moves urine from the bladder out of the body), causing lower urinary tract symptoms, and as a result cause significant reduction in quality of life.
