Fibroadenomas are the most common type of benign (noncancerous) tumors of the breast. Fibroadenomas are often discovered during a breast exam as moveable, painless, firm or rubbery lumps with well-defined borders. Although typically solitary lumps, fibroadenomas can occur in both breasts, or in multiple sites in one breast.

Although the cause of fibroadenomas remains unknown, they tend to occur more frequently in young women between the ages of 20 and 30 and in African-American women.

Diagnosing and Treating Fibroadenomas

After performing a clinical breast exam, your Lahey health care provider may send you for a mammogram and/or ultrasound to gather more information about your particular breast lump. This information will then be combined with your exam results to assist in making further recommendations. If your breast lump is suggestive of a fibroadenoma, your different treatment options may include close observation with ongoing breast exams or scheduling a diagnostic biopsy. The specialists at the Comprehensive Breast Health Center will help you determine the best course of treatment for your particular circumstance.
