Angiosarcoma
Angiosarcoma is a rare, aggressive cancer that forms in the lining of blood vessels and lymph vessels. It can occur anywhere in the body but most commonly affects the skin of the head and neck.
Characteristics and Behavior
Angiosarcoma is known for its rapid growth and high potential to spread (metastasize) to other parts of the body. It often presents as a bruised or purplish area on the skin, which can be mistaken for a benign condition.
Symptoms
Symptoms of angiosarcoma include a growing skin lesion that may look like a bruise, a growing lump, swelling, pain, and skin changes over the affected area. If the tumor is internal, symptoms may include pain or swelling in the affected organ.
Causes
The exact cause of angiosarcoma is not well understood. It involves genetic mutations that lead to abnormal growth of cells in the lining of blood or lymph vessels.
Risk Factors
Risk factors for angiosarcoma include previous radiation therapy, chronic lymphedema (swelling caused by a buildup of lymph fluid due to damage or blockage in the lymphatic system), exposure to certain chemicals, and genetic predisposition. It is most commonly diagnosed in older adults.
Treatment Options
Treatment for angiosarcoma often involves a combination of surgery, radiation therapy, and chemotherapy. The goal is to remove the tumor and manage any metastasis. The treatment plan is individualized based on the tumor’s size, location, and stage.
