Since 2001 I have had Breast Cancer Bone Mets. I have been kept stable, after a year of one of the Taxane Regimens, with just Herceptin - on a weekly basis - along with once a month Zometa. They now feel I am worsening too fast, in the bones. I have a hole in my Sacrum and was told that 20 radiation treatments would be best for keeping my hips intact. I also have some asymmetric issues in my pelvis. I have had 13 treatments and am having a terrible time with side effects. I have always had stomach issues and had terrible heartburn - for 3 or 4 days - following the last 3 treatments. I have also dropped about 5 pounds which hasn't happened to me in years. I know that the horrible symptoms are directly from the radiation. One of the radiology doctors claims that it isn't. He also says that if I only get 2 treatments, each week, that it could actually encourage tumor growth. How is that possible? I just want to somehow get the treatments, even if I have to do it very slowly, to keep my hips intact. I am very frustrated as I haven't ever been as sick as the radiation (this time around) is making me and I have even had a couple different regimens of chemo - in the past - along with radiation to my upper spine. I just don't understand why only doing 2 treatments a week would actually be worse for me and not better?
