1/2/2016I have 2 sisters who have been diagnosed with invasive ductal breast cancer - 1 @ 41 years old - diagnosed with 2 types of metastatic cancer (+++ and --+), my other sister diagnosed at 45 (--+), both had brca testing was negative. our mother had colon cancer and father had lung cancer. I am now 45 years old - seeking consultation about double mastectomy. Just looking for more information about the actual risk of me getting cancer. I know I am at high risk - but what does high risk really mean?

1/3/2016You may have additional risk factors too, such as starting a family later (after age 30), smoker, alcohol usages, overweight, more sedentary life style-- all are additional risk factors. don't know if any apply to you. To get your actual risk calculated requires an appointment with a genetics counselor. And even though your family members tested negative for BRCA 1 and 2 doesn't mean your family doesn't harbor a gene that we don't have a way of testing for yet. so likely most doctors would group your sisters into a category of carrying some kind of gene. Since there isn't a way to accurately determine what gene they may have, prevents us from in turn testing you for the same gene. 50% of siblings carry the same gene. with luck, you have escaped it. That said, for peace of mind it is very reasonable to consider looking at prophylactic mastectomies with reconstruction. if you can come our way, do. Dr David Euhus, our chief of breast surgery, nationally renowned breast surgical oncologist, is also a breast cancer genetics expert. so you can kill 2 birds with 1 stone. call 443-997-8282. these are big decisions that require experts.
