What happens after an abnormal mammogram? Your questions answered
June 10, 2026
Overview: When an abnormality is found on your mammogram, you’ll be asked to have more testing to decide the next steps.
An annual mammogram is the best way to ensure your breasts are healthy. Don’t panic if you get a “callback” because something on your images looks abnormal.
While it can be scary to think about abnormalities in your breasts, it’s the major reason why mammograms are so important -- to catch anything suspicious earlier than later.
What tests are done after an abnormal mammogram?
The first step will most likely be diagnostic testing to get more focused images or an ultrasound of the specific breast area considered “abnormal.” If everything looks fine or a benign cyst is detected, you’ll return to your normal annual mammogram schedule.
If the abnormality is still concerning, a needle biopsy may be performed to examine small tissue taken from the suspicious spot. A biopsy will determine if a mass is cancerous or benign.
Stay calm, but face your emotions
It’s normal to feel worried and upset if you’re called back for more testing after your mammogram. Remind yourself to take it one day at a time until you know your results and talk with loved ones about your concerns. It’s extremely helpful to talk to someone who has been called back before and find out about their journey.
Remember, most often breast changes or suspicious spots are not cancer and not life-threatening.
What could the breast abnormality be?
There are several benign, or non-cancerous, conditions that may show up on mammogram images, including:
- Cysts: Pockets of tissue filled with fluid
- Adenosis: A lump caused by glands that make breast milk
- Blocked breast ducts: Blocked ducts can become infected and show up as a lump
- Hematoma: Blog clots under the skin
- Lipoma: Painless soft benign tumor made of fat cells
What if it's cancer?
If, unfortunately, you find out you have breast cancer, do your research and make a list of questions to ask our provider. These may include:
- What type of breast cancer do I have?
- What stage of cancer do I have?
- What are my treatment options?
- Has the cancer spread to other areas of my body?
- How do I navigate my insurance coverage?
You’ll want to surround yourself with family and friends who will support you through your treatment plan. The good news: When breast cancer is caught early, treatments are often less invasive and highly effective.
