Cancer is an auto-immune disease that is chiefly caused due to attack of defence mechanism of the body against own body cells. Consequently, unrestricted division of cells takes place in the body thereby leading to cancerous growths. Hence cancer may be found in any part or organ of the body. It may even spread from one part to the other.
