What Are the Benefits of 3D Mammography (Digital Breast Tomosynthesis)

Do you have an upcoming appointment for a mammogram screening? It is understandable if you feel a bit nervous, especially if it is your first time. You might have heard about 3D mammography, also known as digital breast tomosynthesis, which is already used in screening centers worldwide. With 3D mammography, low-dose X-ray images are taken in an arc around the breast, which a computer then reconstructs into thin slices, allowing for more precise visualization of the breast tissue. This advanced technology allows for detecting any abnormalities present, making it an essential tool in breast cancer screening and diagnosis. Rest assured that this process is designed to provide you with the most accurate and comprehensive results possible.

In the past, 2D mammography was the only option available for breast cancer screening. However, with the advancement of medical technology, 3D mammography has been developed to provide more comprehensive and accurate testing. This makes it particularly beneficial for women as it can detect abnormalities more accurately.

With 2D mammography, only 2 x-ray images are taken from different angles (front and side), while 3D mammography captures multiple x-ray images from various angles, creating a 3D image of the breast that is sharper, clearer and shows much more detail of the breast. This allows doctors to examine each captured image in detail, identifying even the tiniest details that may indicate cancer. As 3D mammography takes more images, it is easier to spot small details that may be hidden or blocked by overlapping breast tissue. So, while the process may seem overwhelming, 3D mammography can provide a more thorough and accurate examination.

Understandably, many individuals may feel anxious or concerned about the accuracy and process of breast cancer screenings. Several studies have shown that this new mammography method has high sensitivity, specificity, and cancer detection rates. This means fewer individuals may need to undergo follow-up exams, which can relieve those who may have been nervous about the process. Additionally, studies exploring 3D and 2D mammography have shown even better results than either method alone. Even better, synthetic 2D images, which can be created from 3D mammography, could eliminate the need for digital 2D mammography and the associated radiation exposure. Other studies have found that 3D mammography offers fewer false positives, in women of all ages. This can prevent false alarms and unnecessary stress from an inaccurate test.

It is reassuring to see advancements in medical technologies like 3D mammography focused on detecting breast cancer early. Such progress is bound to significantly impact individuals' lives, giving them access to simpler treatment options and increasing their chances of survival. These developments signify a step forward in the fight against breast cancer and bring hope to those affected by this illness.
