We often hear that the lifetime risk for breast cancer in any woman is about one in eight, but that statistic doesn’t tell the whole story. The risk varies in every age group and breast cancer becomes increasingly more common as women age. At age 30, for instance, the risk is one in 227, according to the National Cancer Institute. By age 70, the risk is one in 26.

While the key risk indicators are age and family history, there are a whole host of risk factors, many of which our medical advisor Dr. Elizabeth Comen covers in this video. The American Cancer Society breaks them down into lifestyle factors – like being overweight and not having children – and factors you can’t control, like inherited genes and race. Understanding your breast cancer risk factors is obviously very important.
