The other thing that was recommended to my sisters as myself and another sister have had breast cancer and a niece is to have a consult with a breast surgeon. He can then determine breast density and recommend what type of screening should be done. ..for instance a breast MRI every 2 years possibly with mammograms and ultrasounds in between. Even though my family are currently gene -ve, they still consider all of us a high risk.
Hope you are able to get the follow up you need and feel confident with tbe diagnosis. This link has some info which may be helpful. Kath x
