Atypical Ductal Hyperplasia (ADH)

Atypical Ductal Hyperplasia, or ADH, occurs when normal cells in the milk ducts of the breasts undergo an abnormal change in number, size, shape and appearance.

While not a form of breast cancer, ADH can increase your risk for developing cancer later on. If the abnormal cells are left untreated, they may become cancerous and can spread to surrounding breast tissue and other areas of the body.

Diagnosis of Atypical Ductal Hyperplasia

ADH typically does not cause any signs or symptoms. It is typically found during a breast biopsy, when a tissue sample is removed from the breast to evaluate abnormalities found on a mammogram.

Treating Atypical Ductal Hyperplasia

Treating ADH generally involves surgery. At Mercy, our fellowship-trained breast surgeons will remove the abnormal cells and can also confirm whether cancer is present in the breast.

Our breast health team will advise you of your options about how to manage ADH post-surgery. These options may include follow-up appointments and tests to screen for breast cancer, preventive medications, invitation to participate in clinical trials, and providing education on how to reduce your risk for breast cancer.
