Breast cancer screening using mammogram and breast ultrasound
What Is a Mammogram?
A mammogram is an imaging test used for breast cancer screening. It uses low-dose X-rays to detect changes in breast tissue, often before symptoms such as lumps can be felt.
Key Points:
- Used for early detection of breast cancer
- Can identify changes not noticeable during self-examination
- Often part of routine breast screening
When Should You Get a Mammogram Screening?
Mammogram screening is commonly recommended for women aged 40 and above, though earlier screening may be advised based on individual risk factors.
Guidelines:
- Age 40–49: usually once a year
- Age 50 and above: usually once every 2 years
- Earlier screening may be recommended if there is higher risk
2D vs 3D Mammogram: What’s the Difference?
2D Mammogram
- Standard method for breast cancer screening
- Produces flat X-ray images of the breast
- Widely used and effective for routine screening
3D Mammogram (Tomosynthesis)
- Creates layered images of the breast
- May provide clearer detail, especially in dense breast tissue
- Can reduce the need for additional imaging in some cases
Which One Do You Need?
The choice depends on your age, breast density, and clinical findings. A breast specialist can advise which option is suitable for you.
What Happens During a Mammogram?
A mammogram is a short procedure that typically takes a few minutes per breast.
Steps:
- The breast is positioned on a flat plate
- Gentle compression is applied to keep the breast still
- X-ray images are taken from different angles
- The process is repeated for both breasts
Some discomfort may be felt during compression, but it usually lasts only a few seconds.
What Do Mammogram Results Show?
Mammogram results may show changes in breast tissue that require further evaluation.
Common findings may include:
- Areas of density
- Microcalcifications
- Structural changes in breast tissue
Important Note:
These findings do not necessarily mean cancer, but additional tests such as breast ultrasound or biopsy may be recommended.
How to Prepare for a Mammogram
Before your appointment:
- Avoid scheduling a week before your period if possible
- Do not apply deodorant, powder, or perfume on the day
What to wear:
- Wear a two-piece outfit for easier changing
When Are Additional Tests Needed?
If a mammogram shows an area that needs further evaluation, your doctor may recommend:
- Breast ultrasound
- MRI of the breast
- Biopsy (in selected cases)
Only a small proportion of patients require further procedures.
Who May Benefit from a 3D Mammogram?
- Women with dense breast tissue
- Younger women undergoing screening
- Patients who require more detailed imaging
