Video: What Is Prostate Cancer?

The prostate is a walnut-sized gland that is located at the base of the bladder and makes semen. Each year, nearly a quarter of a million men in the United States are diagnosed with prostate cancer. Prostate cancer experts Vincent Laudone and Howard Scher of Memorial Sloan-Kettering Cancer Center discuss screening and treatment options for men with prostate cancer, including robotic surgery, radiation therapy, focal therapies, and new drugs to treat advanced (metastatic) prostate cancer.
