an older sister is a 9 yr breast cancer survivor. a younger sister just got diagnosed & is currently in treatment for it. my mom, grandmas & my blood aunts have not ever been diagnosed with it. what are my & my 2 remaining sisters, odds of possibly getting it too?
There is high chance given the family history. Estrogen receptor status must be evaluated. BRCA gene expression must be evaluated to know the status. This is called genetic testing. Refer to oncologist for further information.
