Prostate cancer develops when malignant (cancerous) cells form in the prostate (a male reproductive gland just below the bladder). Prostate cancer often grows slowly and is very treatable when found early.
There are several types of prostate cancer.
Adenocarcinoma. Almost all cases of prostate cancer are adenocarcinomas (cancers that start in tissue that covers glands).
Benign prostatic hyperplasia. A benign (noncancerous) enlargement of the prostate can cause some of the same symptoms as prostate cancer, especially weak urine flow and frequent urination. This benign enlargement may need to be corrected by surgery.
Sarcomas. Sarcomas can also form in the prostate, but this is very rare. See the sarcoma section more information about sarcomas.
