| Cancer | Cancer is an abnormal growth of cells which are damaged and unregulated by the body's normal mechanisms. These cells divide and grow in colonies which eventually become malignant tumors. These tumors invade or grow into nearby organs and structures. Cancer cells from the tumors can break off and spread through the blood stream or the immune system (lymph nodes) to other areas; a process called metastasis. |
