Fibrosarcoma is a type of cancer that develops in the connective tissues, particularly in the fibrous tissues that support and protect organs. It can occur in various parts of the body, including the limbs, trunk, and even the head and neck. This cancer is characterized by the uncontrolled growth of fibrous cells, which can form tumors that may be aggressive and invasive. The exact cause of fibrosarcoma is not well understood, but certain factors, such as previous radiation exposure or genetic conditions like Li-Fraumeni syndrome, may increase the risk. Treatment typically involves a combination of surgery, radiation therapy, and sometimes chemotherapy to manage the disease and improve outcomes.
