Atypical Hyperplasia of the Breast

Atypical hyperplasia of the breast is the development of precancerous cells in the breast. Atypical hyperplasia causes a buildup of cells in the breast tissue. When viewed with a microscope, the cells look different from typical breast cells.

Atypical hyperplasia of the breast isn’t breast cancer. But it’s a sign that you have an increased risk of breast cancer in the future.

Your healthcare team creates a plan to help you manage your risk of breast cancer. Often this includes more-frequent breast cancer screening tests. You also might consider medicines to reduce breast cancer risk.
