Breast Tomosynthesis

What is Breast Tomosynthesis?

Tomosynthesis creates a three-dimensional image of a part of the body, usually the breast, to detect any abnormalities. You may often hear it referred to as '3D mammography'.

Understanding the Tomosynthesis process

Tomosynthesis is similar to a regular mammogram. The breast is compressed and several images are taken from different angles. These images are then combined to create a detailed, 3D image. What makes this method superior is its ability to deliver deeper insights into the breast tissue, ensuring that even the smallest anomalies can be detected early.

During the scan, you'll be asked to stand still while the machine takes multiple images from different angles. The scan typically takes about 10 to 20 minutes, and your images will be reviewed by a radiologist who will then share the results with your doctor.

Why might you need a Tomosynthesis?

1. Early Detection: Tomosynthesis  can help detect breast cancer even in its earliest stages by revealing small tumours that could otherwise be missed in a 2D mammography.
2. Reduced False Positives: Unlike traditional mammography, a 3D scan can provide a clear and comprehensive view of the breast tissue, which helps in reducing false positives.
3. Dense Breasts: Women with dense breast tissue may be advised to undergo tomosynthesis because it produces improved images, increasing the likelihood of detecting cancer.

Tomosynthesis is often prescribed for women who have dense breast tissue. This is due to the fact that dense breast tissue can sometimes obscure or mimic cancers on a regular mammogram, making it harder to establish clear results. A tomosynthesis scan is also recommended for those with a higher risk of breast cancer due to personal or family history, lifestyle factors, or age.

How to prepare for Tomosynthesis?

Preparation for tomosynthesis is similar to that of a conventional mammogram. You'll need to avoid applying any lotions, creams, powders, or deodorants on your chest area on the day of the test, as these can affect the imaging. Wearing a two-piece outfit might be more convenient, as you'll be asked to undress from the waist up during the procedure.
