Trends, Outcomes, and Costs of Surgical Excisional Biopsy for Fibroadenoma of the Breast.

Background: De-escalating the management of fibroadenoma of the breast has been encouraged, but it is not known whether this has been successful. A better understanding of the costs and benefits of surgical excisional biopsy is essential for managing individual patients and health systems.

Methods: Prospectively maintained data sources from the Johns Hopkins regional health system were used to capture trends in the rate of diagnosis and excision of fibroadenoma of the breast.
