The short answer

The short version
Getting a call to come back after a mammogram can be frightening. Here is the thing to know up front. A callback means the radiologist wants more images of one area. Most callbacks turn out not to be cancer. It is a request for a clearer picture, not a verdict.
Why callbacks happen
A callback means the radiologist saw an area on your screening mammogram that needs more imaging. In NCI's BI-RADS system, this is category 0, "need additional imaging evaluation." Radiologists also compare your newest mammogram with past ones to check for changes. If you can, tell the new facility where your earlier images are kept. Your team can explain what they saw in your case.
What happens at the callback
A callback usually means a diagnostic mammogram. NCI says it takes images from more angles than a screening mammogram, so the radiation dose is higher. Your team may add other tests. Depending on the result, they may suggest a follow-up mammogram in 6 months (BI-RADS category 3) or a biopsy (categories 4 and 5). Ask when you will hear results.
Keeping it in perspective
NCI says most people who are called back are not found to have breast cancer. It is completely natural to feel anxious in the meantime. Try to hold the appointment as a step toward a clearer answer, not as bad news. The extra views and the comparison with past images help the team decide what happens next.
When to get help sooner
A callback itself is not an emergency. Still, a few things should not wait for the appointment.
- Call your care team the same day if you notice a new lump, bloody or clear fluid from the nipple, skin that dimples or thickens, a nipple that turns inward, a breast that is red, hot, and swollen, or any other change in your breasts. NCI says to contact your doctor about any change.
- Call your care team within a day or two if you cannot get a callback appointment within a few weeks, or if you have not been told your callback results by the date you were given.
Do not skip or delay a callback because you feel well.
What to ask
Ask why you are being called back. Ask what extra tests you will have. Ask whether you will get results the same day, and what the next steps could be. Your care team can walk you through the plan, which is what applies to your situation.
