Living with Angiosarcoma

A rare, aggressive soft tissue cancer that starts in the cells lining blood or lymph vessels, most often in the skin or breast.

Understanding Angiosarcoma

Angiosarcoma is a rare and aggressive soft tissue sarcoma that begins in the cells that line blood vessels or lymph vessels.

It can occur anywhere in the body. It is most often found in the skin and breast, but may also occur in the liver, spleen, and other deep tissues, and is often already spread when diagnosed. Lymphedema (swelling from lymph fluid buildup) often comes before it, for example after breast cancer treatment. Other links include earlier radiation and exposure to some chemicals. GARD lists the onset as adulthood.
