Tumor

A tumor is an abnormal mass or lump that grows within the body. Tumors can be either benign (non-cancerous) or malignant (cancerous), and they can occur almost anywhere in the body. While the cause of tumors is not always known, they may be caused by a variety of factors, including genetics, lifestyle choices, and exposure to carcinogens. Treatment for tumors depends on their type and location, and may include surgery, radiation therapy, and chemotherapy.
