Sarcoma is a type of cancer that arises from connective tissues, such as bone, muscle, fat, cartilage, or blood vessels. Unlike carcinomas, which originate in epithelial cells, sarcomas are relatively rare and can occur anywhere in the body.

There are many subtypes, including osteosarcoma (bone), liposarcoma (fat), and leiomyosarcoma (smooth muscle). Sarcomas may grow and spread quickly, making early detection and treatment important. Management often involves a combination of surgery, radiation therapy, and chemotherapy, depending on the type, size, and location of the tumor.
