What Happens After an Abnormal or High-Risk Mammogram Result?

Getting called back after a mammogram, or seeing the words "abnormal" or "high risk" on your report, can be frightening. Take a breath. A callback is common, and most of the time it does not mean cancer.¹

This guide explains what these results actually mean, what tests may come next, and how to think about the difference between an abnormal finding and a high-risk score.

These terms are often confused, but they mean different things:

• An abnormal result means the radiologist saw something on your mammogram that needs a closer look. It does not mean cancer was found.¹

• A high-risk result usually refers to a risk score suggesting you have an elevated chance of developing breast cancer in the future. It is a forecast, not a finding on the image.

Understanding which one you received helps you know what comes next.

Radiologists summarize mammogram findings using a standardized score called BI-RADS, ranging from 0 to 6.²

Category 4 is further divided into 4A (low, roughly 2 to 10% chance), 4B (moderate, 10 to 50%), and 4C (high, 50 to 95%).³

Being called back is more common than many people realize. About 10 out of 100 women are asked to return after a screening mammogram for another look, and this is even more common with a first mammogram or in younger women.¹

The reassuring reality: only about 3 out of every 1,000 mammograms lead to a cancer diagnosis.¹ A callback usually just means the radiologist wants clearer images, not that something is wrong.

Depending on your BI-RADS category, the next step may include one or more of the following:

• A diagnostic mammogram. This uses additional, targeted views such as spot compression or magnification to examine the area of concern. Unlike a screening mammogram, it is often read while you wait.⁴

• A breast ultrasound. Sound waves help distinguish a fluid-filled cyst from a solid mass.

• A breast MRI. In some cases, MRI provides more detail about a finding.

• A biopsy. If an area remains suspicious, a small tissue sample is taken and examined under a microscope. This is the only way to know for certain whether a finding is cancer.³

The word "biopsy" can sound alarming, but a recommendation for one does not mean you have cancer. Of the women who return for repeat imaging, only about 8 to 10 out of 100 go on to need a biopsy, and about 80 out of 100 breast biopsies turn out to be benign.¹ A biopsy is simply the most reliable way to get a clear answer.

A high-risk result is different from an abnormal finding. It usually comes from a risk model or an AI tool that estimates your future risk, and it does not mean cancer is present. Newer guidelines flag a 5-year risk of 1.7% or higher as increased risk.⁵ If you receive a high-risk score, your doctor may recommend:

• More frequent or earlier screening

• Adding a breast MRI to your mammograms⁶

• Genetic counseling, if your history warrants it

• A discussion of risk-reducing options

In other words, a high-risk score is a prompt to be proactive, not a diagnosis.

Waiting for additional testing or biopsy results is often the hardest part. It is normal to feel anxious. Leaning on trusted friends or family, asking your care team how and when you will get results, and keeping in mind how often callbacks turn out to be benign can all help you through the wait.

Always follow through on recommended follow-up imaging or biopsies, even when you feel well, since early evaluation is what makes early detection possible. And if you notice a new breast lump, skin changes, or nipple discharge at any time, contact your doctor promptly rather than waiting for your next scheduled mammogram.

No. An abnormal result means the radiologist wants a closer look at something, and most callbacks are not cancer. Only about 3 in 1,000 mammograms lead to a cancer diagnosis.¹

BI-RADS 3 means a finding is probably benign, with under a 2% chance of cancer, and usually calls for short-interval follow-up. BI-RADS 4 means a finding is suspicious enough to recommend a biopsy.⁴

It varies by facility, but results often come within a few days to a week. Ask your care team when and how you will receive them.

No. A high-risk score estimates your future risk of breast cancer, while an abnormal mammogram means something on the current image needs a closer look.

Following through on your results is the most important thing you can do, because early evaluation leads to early detection, when treatment works best. And if your screening mammogram came back clear, that same image may still have more to tell you.

The Clairity Breast™ Cancer 5-Year Risk Assessment, available through Everlywell, uses FDA-authorized AI-driven software to analyze a routine screening mammogram from the last 12 months and estimate your personalized five-year breast cancer risk, giving you the "high risk" side of this article's picture before any abnormal finding appears. Provider-reviewed results are delivered to your My Everly account with guideline-based information to review with your health care provider. Clairity Breast estimates future risk; it does not detect or diagnose cancer, it is not a substitute for follow-up imaging or a biopsy your doctor has recommended, and it is not a replacement for mammograms or ongoing care with your provider.

If you have questions about your mammogram results, bring them to your doctor. Everlywell is here to help you stay proactive about your health.
