Cancer is a disease characterized by the abnormal growth and spread of cells in the body. These cells divide uncontrollably, forming tumors that can invade nearby tissues and organs. Cancer can develop in any part of the body and is typically caused by genetic mutations or exposure to carcinogens. It can be life-threatening if not detected and treated early. Common treatments include surgery, chemotherapy, radiation therapy, and targeted therapy aimed at destroying or controlling cancerous cells.
