Getting a call from your hospital asking you to return after a mammogram can be worrying. Your mind may immediately jump to the worst-case scenario. You may wonder whether you have breast cancer, whether more tests will be painful, or what happens next.

But here is something important to remember: an abnormal mammogram does not automatically mean you have breast cancer.

Many abnormal screening results turn out to be non-cancerous. Sometimes, the radiologist simply needs additional images to understand an area more clearly.

Understanding what happens after an abnormal mammogram can help you approach the next steps with greater confidence and less uncertainty.

At Koshys Hospital, Ramamurthy Nagar, Bengaluru, we believe that breast cancer awareness includes not only knowing when to get screened but also understanding what to expect if further testing is recommended.

A mammogram is an imaging test that uses low-dose X-rays to examine breast tissue. It can identify changes that may not be noticeable during a physical examination.

An abnormal mammogram means that the images show an area that needs further assessment. It does not necessarily mean that cancer is present.

The radiologist may identify:

• An area of increased density
• Small calcium deposits known as calcifications
• A mass or lump
• An area where the breast tissue appears different from the surrounding tissue
• A change compared with an earlier mammogram

Some of these findings are caused by normal variations in breast tissue or benign breast conditions. Others may require more detailed investigation.

The next step depends on the type of finding, its appearance and your medical history.

There are several reasons why you may be asked to return after a mammogram.

1. The Images Need to Be Examined More Closely

Sometimes, the original mammogram does not provide enough information to assess an area clearly. Additional mammographic views may help the radiologist understand whether the finding is significant.

2. A Breast Lump or Mass Needs Further Evaluation

If an area looks different from the surrounding tissue, additional imaging may help determine its characteristics.

A breast ultrasound may be recommended to provide more information about a lump or mass.

3. Small Calcium Deposits Need Assessment

Calcifications are tiny calcium deposits that can appear on mammograms. Many are harmless, but certain patterns may require closer examination.

The radiologist considers their appearance and distribution when deciding whether further testing is needed.

4. There Is a Change Compared with Previous Images

Comparing current images with previous mammograms can help identify whether an area is new, stable or changing over time.

This is one reason why keeping previous breast imaging reports can be helpful.

The next steps depend on the finding. Not everyone needs every test.

Step 1: Additional Mammogram Images

The radiologist may request additional views or specialised mammographic images to examine the area more clearly.

These images can sometimes resolve the concern without the need for more invasive testing.

Step 2: Breast Ultrasound

A breast ultrasound uses sound waves to create images of breast tissue.

It may help determine whether a finding is a fluid-filled cyst or a solid mass and provide additional information about an area seen on mammography.

Ultrasound is also useful when evaluating certain breast symptoms. The choice of test depends on the individual clinical situation.

Step 3: A Breast Biopsy, If Needed

If imaging shows an area that cannot be confidently classified as benign, a biopsy may be recommended.

During a breast biopsy, a healthcare professional collects a small tissue sample from the area of concern. The sample is examined in a laboratory to determine whether cancer cells are present.

A biopsy is the most definitive way to establish whether a suspicious breast abnormality is cancerous.

Important: A recommendation for a biopsy does not mean that cancer has already been confirmed. It means that the tissue needs further examination.

Step 4: Review the Results with Your Doctor

Once the necessary tests are completed, your doctor will explain the findings and discuss what they mean.

Depending on the results, you may be advised to return for routine screening, undergo follow-up imaging, receive treatment for a benign condition or consult a specialist for further care.

No. Many abnormal mammogram results are not cancerous.

Possible explanations include benign cysts, fibroadenomas, overlapping breast tissue and other non-cancerous changes.

However, it is equally important not to ignore an abnormal result simply because many findings turn out to be harmless.

The purpose of further testing is to distinguish between findings that are benign and those that need treatment.

A normal mammogram is reassuring, but it cannot detect every breast cancer.

If you notice a new lump, persistent skin changes, nipple discharge or another unusual breast change after receiving a normal result, consult your doctor.

Depending on your symptoms, the doctor may recommend a clinical examination, ultrasound, diagnostic mammography or another appropriate investigation.

Do not assume that a previous normal mammogram means that a new symptom can be ignored.

Yes. Screening mammography can identify certain breast cancers before they become large enough to feel as a lump or cause other noticeable symptoms.

This is one reason screening is important for people who meet the recommended age and risk criteria.

However, screening is not perfect. Some cancers may not be visible on a mammogram, and some abnormalities detected through screening may not be cancerous.

Regular screening, awareness of breast changes and appropriate follow-up all play different roles in breast health.

If you have been asked to return after an abnormal mammogram, a few practical steps can help.

• Bring your previous mammogram reports and images, if available
• Carry any relevant medical records
• Tell the doctor about any breast symptoms you have noticed
• Share your personal and family history of breast cancer
• Ask why the additional test is recommended and what the possible results could mean
• Confirm when and how you will receive your results

If you are anxious, consider taking a trusted family member or friend to the appointment for support.

Most importantly, do not postpone a recommended follow-up simply because you are afraid of the result.

1. How common are abnormal mammogram results?

Abnormal findings occur in breast screening, and many lead to additional tests that ultimately show no cancer. The likelihood of cancer depends on the specific finding and individual circumstances.

2. How long does it take to receive mammogram results?

The timing varies by facility and the type of examination. Ask the imaging centre when to expect your report and whom to contact if you have not received it.

3. Is a breast biopsy painful?

Many breast biopsies are performed using local anaesthesia. You may feel pressure or temporary discomfort, but the experience varies depending on the procedure. Your healthcare professional can explain what to expect.

4. Can breast ultrasound confirm that a lump is not cancer?

Ultrasound can help characterise a lump, but imaging alone cannot always establish a definitive diagnosis. Further investigation or biopsy may be required when findings are suspicious or uncertain.

5. Should I worry if my report recommends follow-up imaging?

It is understandable to feel worried, but follow-up imaging does not automatically mean cancer is present. It is a way to obtain the information needed to assess the finding properly.

An abnormal mammogram can bring uncertainty, but understanding the process can make the next steps easier to navigate.

The most important thing is to complete the recommended investigations, discuss your results with a qualified healthcare professional and follow the advice provided for your individual situation.

For women in Ramamurthy Nagar and surrounding areas of Bengaluru, Koshys Hospital provides a point of contact for enquiries about relevant breast imaging and diagnostic services.

If you have been advised to undergo a mammogram, breast ultrasound or further evaluation, seek appropriate medical guidance rather than delaying care because of fear.

An abnormal result is a reason to investigate, not a reason to assume the worst.
