What is cardiac angiosarcoma?
First described by doctors in 1934, cardiac angiosarcoma is a rare form of cancer that causes cells inside the blood vessels of the heart to multiply and form tumors. The cancerous cells are often found in blood vessels lining the musculature of the wall of the heart, said Dr. Robert Maki, a medical oncologist and the clinical director of the Sarcoma Program at Penn Medicine in Philadelphia.
These cancers are part of a larger family of cancers called sarcomas, which affect the connective tissues that support and surround other parts of the body, including muscle, fat and blood vessels. Angiosarcomas are a kind of sarcoma that specifically afflict cells that line blood vessels, and cardiac angiosarcomas are angiosarcomas that occur within or around the heart.
