The prostate is a small gland found just below the bladder surrounding the urethra, the tube urine passes through. This is an adenocarcinoma, a malignant (cancerous) tumour that arises from the lining (epithelium) of glandular tissue.

Treatment is with hormone therapy, radiation therapy, chemotherapy or surgery to remove the prostate.
