A desmoid tumor is a rare, non-cancerous growth that arises from connective tissue, often found in the abdomen, arms, or legs. These tumors can vary in size and may cause discomfort or pain, but they do not spread to other parts of the body like cancerous tumors do. Desmoid tumors are sometimes associated with genetic conditions, such as familial adenomatous polyposis (FAP). Treatment options may include surgery, medication, or observation, depending on the tumor's size and symptoms. Regular monitoring is essential, as these tumors can recur after treatment.
