On average, about 13 out of 100 women will get breast cancer sometime during their lives. A woman's risk may be higher or lower depending on different factors. Getting older and being female are the two main risk factors linked to breast cancer. Other risks include having a family history of breast cancer, having breast changes or a breast disease that isn't cancer, being white, and drinking alcohol. Hormones such as estrogen may also play a part in some types of breast cancer.
