If not caught very early the disease is a nightmare.The side effects of treatment can lead to many additional problems such as heart damage and nerve damage (both of which I am left with). A healthy lifestyle and yearly mammograms may help but can't prevent it from happening. I am thin, excercise and eat right with no family history of the disease. I have never missed my yearly mammogram, yet 4 months after my mammogram I was in stage 3 breast cancer due to a very aggressive type of breast cancer I was 45. If you know your chances are very high that you will get the disease I don't blame women one bit for doing the procedure. It is a very personal choice and not one easily made. Yes they can still get cancer but the chances of it being breast cancer is very low. Only 5-10%. If you do not have bc to start and do the procedure you can not get bc in another part of your body. You have to have the disease in order for it to metastasize to distance locations. You can get a different cancer, yes. We don't smoke for heart and lungs. Eat right, excersise, etc.... these are all preventive for good health and prevent disease. When your chances of getting bc are over 80% then this procedure is also preventive. Once you get the disease even after the double mascetomy the chances of recurrence is always there. Living with this fear is not easy for anyone. This is a very personal choice and we should never judge another person for their choice if it is a choice that we have never had to make.
