CANCERS

Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells in the body. It can occur in nearly any organ or tissue, such as the lungs, breast, prostate, colon, skin, and blood. Cancerous cells can form tumors or circulate through the bloodstream, leading to metastasis (spread to other parts of the body). Common symptoms include unexplained weight loss, fatigue, pain, or changes in skin or bodily functions. The causes of cancer include genetic mutations, environmental factors, smoking, and certain infections. Treatment options vary, including surgery, radiation therapy, chemotherapy, immunotherapy, and targeted therapies, depending on the type and stage of cancer. Early detection and prevention strategies improve treatment outcomes.
