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.)

What is angiosarcoma of the breast?

Angiosarcoma is cancer that starts in the cells that line blood vessels or lymph vessels. It very rarely occurs in people who had breast radiation to treat breast cancer. It can cause skin changes and/or a lump in the breast. 

How is angiosarcoma treated?

Angiosarcomas tend to grow and spread quickly. Treatment usually includes surgery to remove the breast (mastectomy), and is generally the same as for other sarcomas. For more information on sarcomas, see soft tissue sarcomas.
