Computer-aided Mammography: Should You Consider It?
Breast cancer is the most common type of cancer in American women. Chances of successful treatment are the greatest when the cancer is detected in its early stages. Mammography is a screening test which creates images of the breasts so a radiologist can locate suspicious areas. Mammography is not perfect and researchers are working on ways to improve its accuracy. One type of technology to try make mammograms better is computer-aided mammography, also known as computer-aided detection (CAD).
What Is Computer-aided Mammography? TOP
In traditional mammography, a radiologist reviews an x-ray of the breast to locate any suspicious areas and determine whether further diagnostic testing is necessary. With CAD, the radiologist uses a computer program to help detect suspicious areas on a mammogram after the initial review is done.
What Does the Evidence Say? TOP
The evidence does not all agree, but there are a few conclusions that may be drawn.
What Should You Do? TOP
Researchers are continuing to look for ways to improve the accuracy of mammography. CAD is one of the many types of breast imaging technologies available today, including ultrasound, digital mammography, and MRI.
When scheduling your next mammogram, you may want to find out if CAD or another advanced breast imaging technology is available in your area. If it is, you and your doctor can decide if the technology is right for you. If your facility does not offer CAD, remember that the most important consideration for getting a quality mammogram is having a well-trained radiologist read the results.
