Prostate cancer is cancer that occurs in a man's prostate which is a small walnut-shaped gland that produces the seminal fluid that nourishes and transports sperm. It usually grows slowly and initially remains confined to the prostate gland, where it may not cause serious harm. While some types of prostate cancer grow slowly and may need minimal or no treatment, other types are aggressive and can spread quickly.

Treatment: Radiation therapy uses high-powered energy to kill cancer cells. Prostate cancer radiation therapy can be delivered in two ways: Radiation that comes from outside of your body (external beam radiation). Radiation placed inside your body (brachytherapy). Hormone therapy will stop your body from producing the male hormone testosterone. Prostate cancer cells rely on testosterone to help them grow.
