Breast Hyperplasia

It can occur in the ducts (atypical ductal hyperplasia or ADH) or the lobules (atypical lobular hyperplasia or ALH). Having atypical ductal hyperplasia has been shown to slightly increase the risk of developing breast cancer in the future. Atypical lobular hyperplasia is a form of lobular neoplasia.

The most common symptoms of hyperplasia are lumps on the breast, although these lumps do not necessarily indicate hyperplasia (or, for that matter, breast cancer). In fact, 50 to 90 percent of all women, at some point in their lives before they reach menopause, experience breast pain, lumps or nipple discharge. If you have any of these conditions, please see a doctor immediately. Even if there are no symptoms, however, hyperplasia may show up during a routine breast exam or mammogram.
