Carcinoma

Carcinoma is a type of cancer that begins in the epithelial cells, which line the surfaces of the body, such as the skin, organs, and tissues. It occurs when these cells grow uncontrollably due to genetic changes, forming a tumor. Carcinomas are among the most common cancers and can develop in many parts of the body, including the lungs, breast, colon, and skin. They may invade nearby tissues and spread to other parts of the body (metastasize). Early detection and treatment are crucial for managing carcinomas effectively.
