To refuse radiotherapy at 66, had surgery for left side breast cancer with clear margins, taking Letrazole. I worry damage to lung or heart would hasten the end for me. Finally had a phone consultation with oncologist after 3 cancelled, rearranged appointments. Oncologist did not seem to be aware of my previous partial right side pneumonectomy,& still says radiotherapy x 5 . I want to refuse . Anyone know of survival if damage done & still alive? Sorry if I have upset others. I need to be cautious.
