Angiosarcoma of the Breast
Angiosarcoma of the breast is rare. It's usually a complication of previous radiation treatment to the breast. It can also occur in the affected arms of women with lymphedema, but this is rare. (Lymphedema is swelling that can develop after surgery or radiation therapy to treat breast cancer.)
