Although heart tumors do occur, the vast majority of them are noncancerous (benign).MoreIs there such a thing as heart cancer?
Answer From Timothy J. Moynihan, M.D.
Heart cancer (primary cardiac tumor) is cancer that arises in the heart. Cancerous (malignant) tumors that begin in the heart are most often sarcomas, a type of cancer that originates in the soft tissues of the body. The vast majority of heart tumors are noncancerous (benign).
Heart cancer is extremely rare.
