Solid Breast Masses Diagnosed as Fibroadenoma at Fine-Needle Aspiration Biopsy: Acceptable Rates of Growth at Long-term Follow-up

Abstract

Solid breast masses diagnosed as fibroadenomas at FNAB may be safely followed up if volume growth rate is less than 16% per month in those younger than 50 years and less than 13% per month in those 50 years or older. Acceptable mean change in dimension for a 6-month interval is 20% for all ages.
