Cancer
Everyday, thousands of the body’s cells grow, divide and die. While some cells develop abnormally, due to damage to the DNA, the body is usually able to repair and correct problems. Cancer occurs when there is a sudden increase of abnormal cells, which continue to multiply and eventually outnumber the normal cells. While most cancerous cells lump together to form a tumor, those that involve blood and blood forming organs circulate through tissues.
