Brenda has brought up an extremely important suggestion: having a knowledgeable cardiologist on board. Drs. Douglas L. Mann and Ronald J. Krone, both of the Division of Cardiology, Washington University School of Medicine, St. Louis, put this situation into perspective.
"The management of heart disease in all its forms in patients with cancer in all its forms presents special challenges to the cardiologist. In the war on cancer, the cardiologist is not in the front lines, directly confronting the enemy, but in the role of support and supply, providing the oncologist the ability to keep the warrior strong enough to defeat the enemy. In fighting the war on cancer, there is, like in any war, unwanted 'collateral damage.' There is no 'silver bullet' but, in many ways, a refined shotgun, blasting the tumor while pellets hit other vital organs. The bone marrow, liver, and nervous system get their share of hits; but the heart and vascular system are certainly at risk depending on the weapon used, particularly because the vascular system and blood supply are intimately involved in any treatment delivery. Just as in a war, not only must the enemy be destroyed; but the damage must be contained to permit the rebuilding of the homeland."
