In brief: See genetics

Most breast cancer is NOT due to an inherited risk, but rather occurs by chance.
Family history that suggests an inherited risk, such as changes in the BRCA1 gene or BRCA2 gene, include multiple relatives with cancer over more than one generation and younger ages of onset. If you are concerned about an inherited risk, see a geneticist who can assess your family history.
