Breast Imaging Reporting And Data System (BI-RADS)

The American College of Radiology (ACR) has established a uniform way for radiologists to describe mammogram findings. The system, called BI-RADS, includes seven standardized categories, or levels. Each BI-RADS category has a follow-up plan associated with it to help radiologists and other physicians best manage a patient's care. :

BI-RADS Category	What It Means	Follow Up
0	More information is needed to give a final mammogram report.	More imaging is needed before a category can be assigned.
1	Your mammogram is normal.	Continue annual screening mammograms (for women over age 40).
2	Your mammogram shows benign (noncancerous) findings.	Continue annual screening mammograms (for women over age 40).
3	Your mammogram findings are probably benign.	A 6-month follow-up mammogram is recommended.
4	Your mammogram shows a suspicious abnormality.	You may need biopsy.
5	Your mammogram shows a change that is highly suggestive of cancer.	A biopsy is necessary.
6	Your mammogram shows a cancer that has been proven by biopsy.	A biopsy confirms presence of cancer before treatment begins.
