What if my screening mammogram shows a problem? Are there any problems with mammograms?

No perfect test. It is possible that what is picked-up on a mammogram is not cancer. Unfortunately, there is overlap between the benign and malignant. This is why additional tests (such as ultrasound) are necessary.
Diagnostic Mammogram. The purpose of a screening test is to find as many cancers as possible. If an abnormality is seen, we will get a closer look with a DX mammogram +/- an ultrasound; this may then lead to a (nonsurgical) needle biopsy. When we recommend biopsy, only about 15-30% of the time do we find cancer. One may look at this as a problem, but i feel it's better to "over-biopsy" than to miss a cancer.
Why are you. getting screened at age 24, are you a BRCA carrier or is the listed age incorrect? In any case, about 10% of the time a screening mammo will show a potential abnormality requiring extra imaging. 80% of the time, after the extra views, it turns out to be nothing of concern. Of the remainder that go to biopsy, 80% of those turn out benign.

Additional tests. In most cases, additional mammogram views or an ultrasound of the area or both will be the next step. It is important not to delay follow-up on abnormal test results. Ultimately, if a concern persists a biopsy will be necessary. Be sure to explore minimally invasive biopsy options with your breast specialist such as ultrasound or mammogram guided needle biopsy.
