Two of my close relatives have had breast cancer. Does that mean that I will get breast cancer, too?
Having two relatives on the same side of the family with breast cancer can be significant. However, even if your mother, sister or daughter has had breast cancer, this does not mean that you will definitely get breast cancer. In addition, it is important to remember that hereditary cancer risk can be passed down from your mother or your father. When looking at your family medical history, you need to look at both sides of the family.
