If anyone has read my posts you are probably aware that I take a great interest in cell and cancer biology. So for my next question I want to ask about cancer once again. Now from reading different books and viewing different sites I have come to learn of cancers of the neck, head, bone, muscle, you name it. But one thing I never did see mention in association with cancer is the heart. Is it possible for the heart to develop cancer cells, or more precisely is it possible for the musscle cells in the heart to mutate into cancer cells?
