Why I Was Recalled After a Mammogram

The Short Answer

A mammogram recall — the notification that you need to return for additional imaging — happens to approximately 10 percent of women after a screening mammogram. The vast majority of callbacks do not result in a cancer diagnosis. They result in a clear additional image, a finding that needs monitoring, or a benign result that requires no treatment. That number — roughly 95 percent of recalls that end without a cancer finding — is the most important piece of information to hold onto between the callback notification and the follow-up appointment.

Being recalled after a mammogram is not a diagnosis. It is a request for more information. The radiologist saw something they want to look at more closely — and in most cases, looking more closely confirms that nothing requires treatment.

What a Mammogram Recall Actually Means

When a radiologist reviews a mammogram and sees something that warrants a closer look — an area that needs additional imaging, a finding that was not present on a previous scan, a density that obscures part of the image — they issue a recall. The notification typically arrives as a letter, a phone call from your imaging center, or a message through a patient portal.

The recall letter or call will usually specify that you need to come back for additional imaging but will often not tell you exactly what was seen or why. This lack of specificity is one of the most anxiety-producing aspects of the experience — the pause between notification and follow-up appointment in which you do not know what category your finding falls into.

Asking the imaging center or your ordering physician to tell you, specifically, what category of finding prompted the recall is completely reasonable and can reduce anxiety significantly. The possibilities range from something as simple as a positioning issue on the original image (which requires only a repeat scan) to calcifications, asymmetry, or a mass that needs characterization by ultrasound or additional mammogram views.

The Most Common Reasons Women Are Recalled

Asymmetry. The most common finding that prompts a callback is asymmetry — an area of tissue that appears different from the corresponding area in the other breast. Breasts are naturally asymmetrical, and most asymmetry is normal variation. The concern arises when asymmetry is new (not present on a previous mammogram) or appears in a pattern — focal, linear, or developing — that warrants a second look. Additional imaging, usually another mammogram view combined with an ultrasound, typically resolves whether the asymmetry represents a real finding or was an artifact of positioning.

Calcifications. Calcium deposits appear in breast tissue for many reasons, most of them benign: previous injury, benign cysts, normal aging changes. Certain patterns of calcifications — specifically very fine, linear, or branching microcalcifications clustered in a specific area — can be associated with ductal changes that warrant biopsy. A recall for calcifications typically leads to magnification mammogram views, which provide more detail about the pattern. Most women recalled for calcifications will not be recommended for biopsy.

A mass or nodule. An area that appears to be a distinct structure — round, oval, or irregular — may prompt a recall for characterization by ultrasound. Ultrasound is particularly useful for determining whether a mass is a cyst (fluid-filled, typically benign) or a solid structure (which has a different likelihood profile and may or may not warrant biopsy). Many solid masses are also benign — fibroadenomas are common benign solid tumors in younger women — but they require characterization to make that determination.

Dense breast tissue. Dense breast tissue is extremely common, affecting roughly 40 to 50 percent of women who have mammograms. Dense tissue appears white on a mammogram — the same color as potential abnormalities — which limits the sensitivity of the standard mammogram. A recall in the context of dense breasts often involves a recommendation for supplemental ultrasound or, in higher-risk women, MRI. Many states now require imaging centers to notify women about their breast density because it affects how thoroughly a standard mammogram can evaluate the breast.

Technical issues. Not all recalls signal a finding of concern. A positioning problem that left part of the breast inadequately imaged, motion blur from movement during the exposure, or equipment-related issues can produce a recall that is purely about repeating the image with better technique. These callbacks are typically the least serious in outcome, though they feel identical to finding-related callbacks when you receive the notification.

What Happens at the Recall Appointment

The follow-up appointment is usually at the same imaging center or hospital. You will typically have additional mammogram views — spot compression views, magnification views, or views from different angles depending on what was seen — followed by ultrasound if indicated.

After the imaging is complete, the radiologist will interpret the results and communicate them, either directly at the appointment or shortly afterward. The results will typically fall into one of several categories: the finding was a normal variation or an imaging artifact (callback resolved, no action needed), a clearly benign finding (no action needed, possibly routine follow-up in 12 months), a probably benign finding (short-interval follow-up imaging, typically in 6 months), or a finding that warrants biopsy (tissue sampling to determine what the finding is).

A recommendation for biopsy is not a cancer diagnosis. A significant proportion of biopsies recommended after mammogram recall find benign tissue. The biopsy determines what the finding actually is, which is the only way to know with certainty.

What to Bring to the Recall Appointment

If your original mammogram was done at a different facility than your recall appointment, bring or arrange the transfer of your prior imaging — previous mammograms are essential for comparison, particularly for finding asymmetry or calcifications that may have been present previously (which is generally more reassuring than something new).

Bring any questions you want to ask the technologist or radiologist about what they are looking at and what the follow-up options might be depending on what they find. And bring whoever helps you feel calm while you wait, because the time between the end of imaging and the radiologist’s interpretation is often the hardest part of the appointment.
