Is breast cancer passed down in families even for men?

Yes: While most cases of breast cancer are not related to heredity, those that are can be inherited from either parent. Furthermore, a man that harbors this genetic predisposition is at personal risk for breast cancer and can pass this risk to his children. If you have multiple family members with breast cancer, there is a simple blood (brca test) test to determine if you have inherited that risk.

Possible: Why the majority of breast cancer patients have no family history of breast cancer, there are certain genes that can be passed down. Men who inherit the brca-2 gene have a increased risk of breast cancer. The role of brca-1 in men is unclear.
