I am 71, very active and just learned about 2 weeks ago that I have intraductal carcinoma in situ of the breast. I am having a difficult time trying to determine if I should have a lumpectomy with potential radiation and hormone therapy or a simple mastectomy. This area of calcification was picked up on mammography (yearly study) and they didn't know if I could have had it in 2009 since it is right up against the chest wall which made it difficult to capture via xray. If I should need radiation would proton thereapy be an option. I have had 2 brothers that had this method of treatment for prostate cancer. I really do not wish to take hormone therapy if at all possible because of the side effects that I have read. I would be grateful for your comments. I live about 160 miles away from Oklahoma City. Thank you.
