Mammogram (3D Tomosynthesis)
A mammogram is an X-ray examination of the breast used to detect and diagnose breast disease. Iswarya Hospital houses the Siemens MAMMOMAT Revelation — a state-of-the-art 3D digital breast tomosynthesis (DBT) system that is the most advanced mammography unit in Chennai. Unlike conventional 2D mammography, 3D tomosynthesis captures multiple thin-layer images of the breast from different angles, creating a detailed three-dimensional reconstruction. This dramatically improves cancer detection rates (up to 40% more invasive cancers detected) while reducing false positives and unnecessary callbacks. The system also features a wide-angle tomosynthesis (50°) for superior image quality, PRIME Technology for ultra-low radiation dose, and Comfort Paddle for a gentler, less painful compression experience.
🔬 How the Procedure Is Performed
- 1
You will be asked to undress from the waist up and wear a hospital gown.
- 2
The mammography technologist positions one breast at a time on the imaging plate.
- 3
A compression paddle gently flattens the breast to spread the tissue evenly — our Siemens Comfort Paddle minimises discomfort.
- 4
The 3D tomosynthesis X-ray tube sweeps in an arc, capturing multiple low-dose images from different angles.
- 5
Each breast is imaged in two views — craniocaudal (top to bottom) and mediolateral oblique (angled side view).
- 6
Images are reconstructed into thin slices by the computer and reviewed by a specialist breast radiologist.
✅ Benefits of Mammogram (3D Tomosynthesis)
- ✓Detects up to 40% more invasive breast cancers compared to conventional 2D mammography
- ✓Reduces false-positive recalls by up to 40% — fewer unnecessary biopsies and anxiety
- ✓Superior visualisation in dense breast tissue — critical for Indian women who often have denser breasts
- ✓Ultra-low radiation dose with Siemens PRIME Technology — as low as a standard 2D mammogram
- ✓Comfortable experience with Siemens Comfort Paddle — less pain during compression
- ✓Rapid exam — complete in about 15 minutes with immediate digital results
- ✓Enables early detection at the most treatable stage — improving 5-year survival to over 95%
📋 How to Prepare
- Schedule your mammogram 1–2 weeks after your period, when breasts are least tender.
- Do not apply deodorant, antiperspirant, powder, or lotion to your breasts or underarms on the day of the exam.
- Wear a two-piece outfit so you only need to remove your top.
- Bring any previous mammogram films or reports for comparison.
- Inform the technologist if you are pregnant, breastfeeding, or have breast implants.
⚠️ Possible Risks & Side Effects
- Very low-dose radiation exposure — the dose from a mammogram is equivalent to about 7 weeks of natural background radiation
- Mild breast discomfort during compression — temporary and lasts only a few seconds per image
- Small possibility of a false-positive result leading to additional imaging or biopsy
- Mammography may miss some cancers (false-negative) — 3D tomosynthesis significantly reduces this limitation
Your surgeon will discuss all risks with you before the procedure and take appropriate precautions to minimise them.
💊 Post-Procedure Care
- No recovery needed — you can resume all normal activities immediately.
- Results are typically reviewed by a specialist breast radiologist and reported within 24 hours.
- If any area needs further evaluation, additional imaging (ultrasound or MRI) or biopsy may be recommended.
- Annual screening mammography is recommended for women aged 40 and above.
- Women with a family history of breast cancer or BRCA gene mutations should start screening earlier — consult your oncologist.
❓ Frequently Asked Questions
What is 3D tomosynthesis and how is it different from a regular mammogram?
3D digital breast tomosynthesis captures multiple images of the breast from different angles and reconstructs them into thin slices. This allows the radiologist to examine breast tissue layer by layer, detecting cancers hidden in overlapping tissue that a standard 2D mammogram might miss. It is especially beneficial for women with dense breasts.
Is the Siemens MAMMOMAT Revelation available at Iswarya Hospital?
Yes. Iswarya Hospital is equipped with the Siemens MAMMOMAT Revelation — one of the most advanced mammography systems in the world. It offers wide-angle 50° tomosynthesis, ultra-low dose imaging, and a unique Comfort Paddle for a more comfortable exam.
At what age should I start getting mammograms?
Women aged 40 and above should have an annual screening mammogram. Women with a strong family history of breast cancer, known BRCA gene mutations, or other high-risk factors may need to start screening in their 30s — consult your oncologist.
Does a mammogram hurt?
There may be mild discomfort during breast compression, which lasts only a few seconds per image. Our Siemens Comfort Paddle is designed to reduce pressure and make the experience as gentle as possible.
How much radiation does a 3D mammogram use?
With Siemens PRIME Technology, the 3D tomosynthesis exam delivers a radiation dose comparable to a conventional 2D mammogram — roughly equivalent to 7 weeks of natural background radiation. It is considered very safe.
How often should I get a mammogram?
For average-risk women aged 40+, annual mammography is recommended. For high-risk women, your oncologist may recommend more frequent screening or additional imaging such as breast MRI.
