Should I Be Concerned About Calcifications on My Mammogram?

A callback after your mammogram doesn’t mean anything is wrong.

It’s natural to be concerned any time you get medical test results that come back as anything except 100% normal, especially when the test is a cancer screening. However, it’s important to keep in mind that mammogram follow-up is often a way of looking more closely at structures that may well be perfectly harmless. Although advances in mammography have improved imaging and increased accuracy, depending on the type of mammography used, between 8 and 10 percent of women are still called back for further testing after their annual screening.[1] Of those women who are called back, only 8 to 10 percent undergo biopsy, and 80% of those biopsies ultimately show benign conditions.[2]

 

Calcifications are normal.

A common reason to be called back for further screening is the appearance of calcifications on your mammogram. In themselves, calcifications are harmless. They are simply little calcium deposits that develop with age, injury, or inflammation. About half of women over 50 and 10% of younger women have calcifications in their breasts.[3] Sometimes, the radiologist will look more closely at calcifications if the size and distribution pattern suggests that they may be a result of cancerous cell growth.

 

Certain types of calcifications may suggest the presence of cancer.

There are two general types of calcifications that appear on mammograms: micro (small) calcifications and macro (large) calcifications (see illustrations here). These terms are relative; even macrocalcifications are too small to be felt. They are, however, the larger of the two varieties. Macrocalcifications are typically round and spread throughout the breast tissue in a seemingly random pattern. Microcalcifications are more often irregularly shaped and may appear in clusters.[4] Although both types are usually benign, microcalcifications that appear in a line or cluster can be the earliest sign of developing breast cancer.[5]

If the radiologist determines that calcifications on your mammogram raise a concern that cancer may be present, then follow-up will be recommended. You may simply be asked to come back for additional imaging and monitored over time for changes, or your doctor may recommend a biopsy. Although most follow-up testing comes back normal, it is important that you keep all appointments so your evaluation is as accurate as possible and, in the event that cancer is present, it is identified as early as possible. Breast cancer patients who are diagnosed early tend to receive much less invasive and less debilitating treatments than later-stage patients, and their survival rates are considerably higher.
