What are the different types of prostate cancer?

Dr. Robert E. Reiter, MD

There is generally only one major type of prostate cancer, called adenocarcinoma, that arises from the prostate glands. Other types of cancer can arise from different cells and structures of the prostate, but this is rare.

The prostate is a walnut-sized organ that surrounds the urethra; it produces a fluid that becomes part of semen. More than 99 percent of prostate cancers develop in the gland cells. This type of prostate cancer is called adenocarcinoma.

More rarely, prostate cancer originates in other tissues of the prostate, which is called a sarcoma.
