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.
These occur from damage to genes during a personâs life. They are not passed from parent to child. Factors such as tobacco, ultraviolet (UV) radiation, viruses, and age cause these mutations. Cancer that occurs because of acquired mutations is called sporadic cancer.
