A doctor has provided 1 answer

Blood vessel tumor: A primary angiosarcoma is a rare lesion of blood vessel origin unrelated to the classic ductal or lobular carcinomas. It is aggressive and can be lethal requiring simple mastectomy. It frequently arises secondary to previous radiation of the breast and belongs to the Stewart Treves group of tumors secondary to lymphedema.
