Answer: There's no simple answer to this question. Some abnormal genes are associated with an increased risk of breast cancer. In families that have an abnormal gene, it can be passed down from a parent to a child. Only 10% (1 in 10) of women with breast cancer have inherited an abnormal breast cancer gene.
Changes in other genes: Other gene mutations can also lead to inherited breast cancers. These gene mutations are much rarer and often do not increase the risk of breast cancer as much as the BRCA genes. They are not frequent causes of inherited breast cancer.f you have inherited a mutated copy of either gene from a parent, you have a high risk of developing breast cancer during your lifetime. Although in some families with BRCA1 mutations the lifetime risk of breast cancer is as high as 80%, on average this risk seems to be in the range of 55 to 65%.
