Cancer, also recognized as a malignant tumor or malignant neoplasm, is a group of diseases involving abnormal cell growth with the potential to invade or increase to other parts of the body. Not all tumors are cancerous; benign tumors do not spread to other parts of the body. Possible signs and symptoms include such as a new lump, abnormal bleeding, a prolonged cough, unexplained weight loss, and a change in bowel movements among others.
