bi rads category 3 probably benign finding

Some earlier research suggested that malignancies were so rare in the BI-RADS 3 group that follow-up could be safely pushed back from six months to a year. The interval for follow-up imaging has been a point of contention in the breast imaging community. This assessment means that the lesion is one of a few specific findings that has been shown to have less than a 2 percent chance of being cancer and that any cancer present is not likely to spread in the time frame recommended for follow-up imaging.

Findings are classified based on the risk of breast cancer, with a BI-RADS 2 lesion being benign, or not cancerous, and BI-RADS 6 representing a lesion that is biopsy-proven to be malignant.īI-RADS 3, a probably benign finding, is a particularly challenging category that can cause confusion for physicians and anxiety for patients. The Breast Imaging and Reporting System (BI-RADS) was established by the American College of Radiology to help classify findings on mammography.

Women with mammographically detected breast lesions that are probably benign should have follow-up surveillance imaging at six months due to the small but not insignificant risk that the lesions are malignant, according to a new study published in the journal Radiology. view moreĬredit: Radiological Society of North America The patient preferred biopsy to surveillance, with US-guided core biopsy showing fibroadenoma.
