Yes and No: I think you are really asking if breast cancer is hereditary, meaning is it past from a parent it is possible to inherit a predisposition to breast cancer. There are a few genes known to cause this like brca 1 ; 2 and tests can be done for them. On the other hand all breast cancers have genetic abnormalities. These changes however were not inherited but happened in the patient.
