Follow-up After an Abnormal Mammogram
If the results of your screening mammogram show something abnormal, you’ll need follow-up tests to check whether or not the finding is breast cancer.
Most abnormal findings on a screening mammogram are not breast cancer [62].
For most women, follow-up tests will show normal breast tissue. For other women, follow-up tests will show a benign (not cancer) breast condition. A small number of women will have breast cancer.
It’s important to get follow-up without delay if you have an abnormal screening mammogram. That way, if you have breast cancer, it can be treated as soon as possible. With standard treatment, people who have breast cancers found early have a high chance of survival.

Follow-up tests
If you have an abnormal finding on a screening mammogram, the follow-up tests you’ll have depend on the recommendations of the radiologist (the doctor who read and interpreted your mammogram).
Sometimes, a follow-up mammogram (diagnostic mammogram) or a breast ultrasound is done.
If the finding doesn’t look like breast cancer (for example, it’s a cyst), no further testing is needed and you return to your regular schedule of breast cancer screening with mammograms and clinical breast exams.
In some cases, more tests such as a breast MRI, or even a biopsy, may be recommended.

When a breast biopsy is needed
If the finding looks like it might be breast cancer, the next step is a biopsy. A biopsy removes a small amount of tissue in the breast to check for cancer.
If the biopsy shows no cancer, you return to your regular schedule of screening with mammograms and clinical breast exams.
If breast cancer is found, it can be treated. With standard treatment, people who have breast cancers found by screening mammography have a high chance of survival.
If you’re diagnosed with breast cancer, your medical center may have a patient navigator to help you coordinate your care. Komen also offers free, personalized navigation services to patients, caregivers and family members.
