My mammogram showed a questionable abnormality. what are the chances that i have cancer? what is the next step?

Need more work up: When a mammogram has an abnormality, the next step is to repeat the mammogram with some different views and more compression (squeeze). An ultrasound is performed as well. There are many noncancerous things that can cause an abnormal mammogram. You may also need a biopsy (see core needle biopsy). Make sure you follow through with the recommendations.

Check recommendatios: You need to get a more clear answer as to the type of the abnormality. Some are benign and some are suspicious. Please check with your provider. If there were enough concerns a biopsy maybe needed. Sometimes a short term follow up is suggested. Sometimes additional images and an ultrasound maybe needed. Make sure to get the proper answer from your provider. If needed a biopsy can clear the issue..

Diagnostic mammogram: When a screening mammogram shows an abnormality, the next step is a diagnostic mammogram where they will focus on the abnormality with compression and special views. If there is still something there of suspicion, the radiologist will either recommend a short term follow up or a biopsy. Keep in mind many of these will turn out to be benign.

Additional imaging: to further evaluate a potential abnormality occurs in about 10% of mammograms. 80% of the time it turns out to be nothing of concern. Of the remainder that go to biopsy, 80% of those turn out benign. So the odds favor a benign etiology, but in a small percentage of cases there is a cancer.
