Prostate cancer is cancer that occurs in the prostate — a small walnut-shaped gland in men that produces the seminal fluid that nourishes and transports sperm.

Prostate cancer is the most common type of cancer in men. Usually, prostate cancer grows slowly and is initially confined to the prostate gland, where it may not cause serious harm. However, while some types of prostate cancer grow slowly and may need minimal or even no treatment, other types are aggressive and can spread quickly.

Prostate cancer that's detected early — when it's still confined to the prostate gland — has a better chance of successful treatment. Your prostate cancer treatment options depend on several factors. Urology experts will work with you and your health care team to develop the best treatment plan for you.
