What it means
Incomplete - Additional imaging evaluation and/or comparison to prior mammograms is needed.
This means the radiologist may have seen a possible abnormality, but it was not clear and you will need more tests, such as another mammogram with the use of spot compression (applying compression to a smaller area when doing the mammogram), magnified views, special mammogram views, or ultrasound. This may also suggest that the radiologist wants to compare your new mammogram with older ones to see if there have been changes in the area over time.
There's no significant abnormality to report. Your breasts look the same (they are symmetrical) with no masses (lumps), distorted structures, or suspicious calcifications. In this case, negative means nothing bad was found.
Benign (non-cancerous) finding
This is also a negative mammogram result (there's no sign of cancer), but the radiologist chooses to describe a finding known to be benign, such as benign calcifications, lymph nodes in the breast, or calcified fibroadenomas. This ensures that others who look at the mammogram will not misinterpret the benign finding as suspicious. This finding is recorded in your mammogram report to help when comparing to future mammograms.
Probably benign finding – Follow-up in a short time frame is suggested
The findings in this category have a very high chance (greater than 98%) of being benign (not cancer). The findings are not expected to change over time. But since it's not proven to be benign, it's helpful to see if the area in question does change over time.
You will likely need follow-up with repeat imaging in 6 months and regularly after that until the finding is known to be stable (usually at least 2 years). This approach helps avoid unnecessary biopsies, but if the area does change over time, it still allows for early diagnosis.
Suspicious abnormality – Biopsy should be considered
Findings do not definitely look like cancer but could be cancer. The radiologist is concerned enough to recommend a biopsy. The findings in this category can have a wide range of suspicion levels. For this reason, this category is often divided further:
4A: Finding with a low likelihood of being cancer (more than 2% but no more than 10%)
4B: Finding with an moderate likelihood of being cancer (more than 10% but no more than 50%)
4C: Finding with a high likelihood of being cancer (more than 50% but less than 95%), but not as high as Category 5
Highly suggestive of malignancy – Appropriate action should be taken
The findings look like cancer and have a high chance (at least 95%) of being cancer. Biopsy is very strongly recommended.
Known biopsy-proven malignancy – Appropriate action should be taken
This category is only used for findings on a mammogram that have already been shown to be cancer by a previous biopsy. Mammograms may be used in this way to see how well the cancer is responding to treatment.
