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. | |
