Prostate cancer is a malignant (cancerous) tumour (growth) that consists of cells from the prostate gland. Generally, the tumour usually grows slowly and remains confined to the gland for many years. During this time, the tumour produces little or no symptoms or outward signs (abnormalities on physical examination). However, all prostate cancers do not behave similarly. Some aggressive types of prostate cancer grow and spread more rapidly than others and can cause a significant shortening of life expectancy in men affected by them.
