Ductal Hyperplasia

Atypical ductal hyperplasia is a medical condition where the cells that line the milk ducts of the breasts have abnormal growth. This condition is not cancerous, but can indicate an increased cancer risk for a woman.

Fast Facts:

  • The presence of atypical hyperplasia increases a woman's risk of developing breast cancer to five times the average risk.
  • People with atypical ductal hyperplasia should get more mammograms.
  • Your Doctor may suggest you take a drug, called tamoxifen, which has been shown to lower some women's risk of getting breast cancer.
  • Atypical hyperplasia can be diagnosed only with a biopsy.
