Prostate cancer develops in the walnut-sized prostate gland that makes and stores seminal fluid, a milky liquid that nourishes sperm.
The prostate gland helps regulate bladder control and normal sexual functioning. Prostatecancer develops when the cells in the prostate gland grow more quickly than they should, forming a malignant lump or tumour. Most prostate cancers grow slowly in comparison to other cancers and while the causes are unknown, fatty acids are believed to play a role.
The chance of developing prostate cancer increases with age, and if your father or brother have had the disease.
Occurring mainly in men over 65, and rarely in those under 50, prostate cancer affects more Australian men than any other.
