Prostate Cancer
Cells normally grow and divide to produce new cells, as the body needs them. With BPH an excess of normal cells is gradually formed in the prostate, but with cancer the cells become abnormal. They keep dividing out of control forming a tumor. They can invade and destroy nearby healthy tissue and, at later stages, can break away from the tumor and enter the bloodstream and lymphatic system to spread to other parts of the body. With prostate cancer this mainly involves the bones, bladder, rectum and other organs. No one knows what causes cells to become cancerous, or malignant, but research is looking into various causes. It seems to involve an interaction between a man's genetics and his environment. Certain factors, called risk factors, have been associated with a greater chance of developing prostate cancer, but it is not known if reducing or avoiding these factors can prevent prostate cancer.
