If you've been diagnosed with atypical hyperplasia, you have an increased risk of developing breast cancer in the future. Women with atypical hyperplasia have a risk of breast cancer that is about four times higher than that of women who don't have atypical hyperplasia.

Being diagnosed with atypical hyperplasia at a younger age may increase the risk of breast cancer even more. Women diagnosed with atypical hyperplasia before age 45 have a greater risk of developing invasive breast cancer during their lifetimes, compared with older women, especially those older than 55.
