Disorders

Fibrocystic breast condition (sometimes called fibrocystic complex) is the most common type of benign breast disorder. It was previously referred to as fibrocystic breast disease. Fibrocystic breast condition is a catch-all diagnosis that is used to describe the presence of multiple, often painful, benign breast nodules. These breast nodules vary in size and blend into surrounding breast tissue. However, the histologic changes responsible for the breast nodules could belong to one of several different categories.

The College of American Pathologists has categorized the types of fibrocystic breast condition according to the associated increased risk for subsequent invasive breast cancer and the particular histologic (microscopic) change that is present. These types include the following: no increased risk (nonproliferative changes, including microcysts, adenosis, mild hyperplasia, fibroadenoma, fibrosis, duct, apocrine metaplasia, and gross cysts); slightly increased risk (relative risk, 1.5 to 2; proliferative changes without atypia, including moderate hyperplasia and papilloma); moderately increased risk (relative risk, 4 to 5; proliferative changes with atypia or atypical hyperplasia); and significantly increased risk (relative risk, 8 to 10; ductal and lobular carcinoma in situ).
