Hi Lisa! Welcome to our little section of cyberspace! I have had experience with the MRI. I was part of that big study that was using MRI for screening high risk women for breast cancer (my mother and sister had bc). The results found that the MRI is definately a good idea for high risk, but not for the general population because of the high percentage of false positives. They found a significant number of early cancers that were not found on mammogram or ultrasound. I was one of them! Both my mammo and u/s were "normal"! I was 44 at the time and had large dense breasts. They may not have found anything on a mammo until things got much larger and I might not be here five years later talking about
it! Your radiation treatment puts you in the high risk category and I commend your doctor for suggesting the MRI. He really has your best interest at heart. I am not suggesting that you may have cancer, but this is certainly one of the better diagnostic tools for early detection and that is surely our best defense against this disease. Good luck! Frayda
