Desmoid tumors are rare, non-cancerous growths that arise from connective tissue, specifically from fibroblasts. They can occur in various parts of the body, including the abdomen, limbs, and chest wall. Although they are not malignant, desmoid tumors can be aggressive and may invade surrounding tissues, leading to discomfort or complications. The exact cause of desmoid tumors is not well understood, but they are often associated with genetic conditions like familial adenomatous polyposis (FAP). Treatment options may include surgery, medication, or observation, depending on the tumor's size, location, and symptoms.
