Digital Mammogram: What It Is, Purpose, and Procedure

Mammograms are essential for detecting breast cancer. It is a Diagnostic tool that uses X-rays in low doses to examine breast tissue. Mammograms are used to identify abnormalities that could be early signs of breast cancer before the symptoms begin appearing. When breast cancer is caught early, it greatly increases survival rates.

Mammograms serve both screening and diagnostic purposes.

• Screening mammograms detect early signs of breast cancer when symptoms have not presented themselves yet.
• Diagnostic Mammograms are conducted when symptoms such as lumps, nipple discharge, or breast pain are present.

Types of Mammograms

There are two primary types of mammograms:

1. 2D Mammography: This traditional method captures images of each breast from two angles: top to bottom and side to side.
2. 3D Mammography (Digital Breast Tomosynthesis): A more advanced technique where the breast is compressed once, and multiple X-rays are taken as the machine moves in an arc. The images are combined into “slices,” offering a detailed 3D view of the breast tissue.

Purpose of a Mammogram

A mammogram test is a cornerstone of women’s healthcare and is recommended for routine screening and diagnostic purposes when abnormalities are suspected.

1. Early Detection of Breast Cancer

A mammogram’s primary purpose is to detect breast cancer early on, often before any symptoms, such as a lump or pain, appear. Early detection is crucial as it enhances the likelihood of survival and effective treatment. Mammograms allow for less invasive and more effective therapies by finding cancer while it is still small and localised to the breast tissue.

2. Screening for Asymptomatic Women

When a woman has no symptoms of breast cancer, mammograms are an important screening tool. Regular screening mammography is performed to detect anomalies that clinical breast exams or self-examinations may miss. They may have lumps or microcalcifications (tiny calcium deposits) indicative of cancer or other conditions requiring further investigation. These tests are critical for women who have a family history of breast cancer or a genetic predisposition to the disease.

3. Diagnostic Evaluations

Mammograms are used for diagnostic purposes and routine screening in the event of unexpected findings or complaints. A diagnostic mammogram may be recommended if a woman or her healthcare practitioner discovers a lump, experiences unusual breast pain, or notices changes in the skin or nipple. Compared to a screening mammogram, this type provides more detailed images and focuses on specific areas of concern to help medical experts determine whether more tests or therapies are necessary.

4. Monitoring Breast Health

Mammograms are also useful for monitoring the health of the breasts over time, especially for women who have had benign breast issues or breast cancer previously. By comparing recent photographs to previous ones, doctors may monitor changes in breast tissue, evaluate the efficacy of drugs, and ensure that new concerns are recognised early on.

5. Supporting Personalized Care

The information gathered from mammograms allows healthcare providers to offer personalised care plans. Women with dense breast tissue may require supplemental imaging, like ultrasound or MRI, to improve the accuracy of cancer detection. Similarly, mammograms can guide decisions about preventive measures, such as medications or lifestyle changes, for women at high risk of developing breast cancer.

6. Balancing Benefits and Risks

Although mammograms expose women to a small amount of radiation, the benefits typically outweigh the risks. Technological advancements, including digital mammography and 3D imaging, have reduced radiation doses while enhancing image quality and diagnostic precision.

How Does it Work?

A mammogram is performed using a specialist X-ray machine designed to visualize breast tissue. Compared to routine bone X-rays, mammograms require less radiation.

Throughout the procedure, your breast is supported by a machine-attached plate. A technician uses a paddle to gently squeeze your breast into position. The equipment then emits X-rays that pass through your breast and are detected by a detector on the opposite side. The detector transforms the X-rays into electrical signals, which a computer processes to generate digital mammography images.

Breast compression is required to keep the breast in place and avoid blurry photographs. It also flattens the breast, allowing the X-rays to reach the detector more quickly.

When Will You Receive the Test Results?

You will typically get your mammogram results within a few days, though the timeframe can vary. Radiologists often compare the latest images with previous ones before sending the results to you and your healthcare provider.

If you don’t receive your results within a month, contact your provider or the facility where you had the mammogram.

Preparing for a Mammogram

When scheduling your mammogram, keep the following in mind:

• Pregnancy or breastfeeding: Inform your healthcare provider if you are pregnant, breastfeeding, or suspect you may be pregnant. They may recommend the best time for the mammogram or suggest starting with an ultrasound.
• Menstrual cycle: Avoid scheduling your mammogram during your period or the week before, as your breasts may be more tender, making the procedure uncomfortable.
• Breast implants or recent vaccination: Let the scheduler know if you have breast implants or recently received a vaccine.

On the Day of the Mammogram:

• Stick to your normal routine: You can eat, drink, and take your usual medications.
• Avoid certain products: Do not wear deodorant, perfume, lotion, or body powder, as they may affect the X-ray images.
• Dress comfortably: You’ll need to undress from the waist up for the procedure and will be provided with a medical gown or drape.

What to Expect During a Mammogram?

During a mammogram, you can expect the following steps:

1. Preparation:
   • You will need to remove all clothing and jewelry above your waist.
   • A healthcare provider will give you an open-front hospital gown or drape to wear.
2. Positioning:
   • You will stand in front of the mammography machine.
   • The technologist will position one breast at a time on a support plate.
3. Compression and Imaging:
   • A plastic paddle will gently compress your breast against the support plate.
   • You may feel some pressure or discomfort during compression. If it becomes too uncomfortable, inform the technologist of adjustments.
   • The machine will capture images of the compressed breast.
4. Repetition:
   • If you have two breasts, the process will be repeated for the other breast.
5. After the Procedure:
   • Once the imaging is complete, you can put your clothes back on and leave the facility.
   • Most individuals can return to their normal activities right after the mammogram.

Conclusion

The mammogram is an important tool in modern healthcare since it provides a reliable approach for the early identification, diagnosis, and monitoring of breast health. Mammograms significantly improve treatment outcomes and survival rates by finding potential diseases, such as breast cancer, early. Mammograms let women and healthcare providers make informed decisions about care and prevention, whether for routine screening, symptom assessment, or tracking changes over time. Mammograms’ precision and security continue to improve as technology advances, reinforcing their importance in maintaining women’s health. Along with being a diagnostic tool, regular mammograms play a key role in preserving long-term health and providing peace of mind.
