Abstract Background Androgen suppression treatment AST might increase the risk of cardiac morbidity in prostate cancer patients. Possible explanations were provided however they disregard the potential contribution of prophylactic radiotherapy to the mamillary regions PMRT prescribed to avoid gynecomastia . Methods We studied the exposure of the heart in a typical electron beam PMRT setting by evaluating computed tomography CT scans in 40 non-cancer patients age 65 and 75 years in 50 each and 17 prostate cancer patients. Five of the younger 7 of the older and 4 of the cancer patients had significant cardiac disease. Results The median distance between skin and outer heart contour decreased with age. In all three groups patients with cardiac morbidity had smaller distances. When using the CT-determined PMRT beam .
