2D & 3D MAMMOGRAPHY
SCREENING FOR BREAST CANCER
Doctors and scientists agree that early detection is the best defense against breast cancer. Successful treatment and survival rates for breast cancer patients are dramatically affected by early detection of breast cancers. If we find cancer in its earliest stages, the chances of surviving is good. Until now, the best way to do that has been with digital mammography.
Digital Mammography uses a specially designed digital camera and a computer to produce an image that is displayed on a high-resolution computer monitor.
While digital mammography is still one of the most advanced technologies available today, it is only a two-dimensional picture of the breast. Since the breast is composed of pockets of dense tissue surrounded by fat, when x-rayed, it creates an image that looks something like a smoky haze. The overlapping tissue in the image makes it difficult to see tiny “spots”, called micro calcifications, and other subtle signs of early cancer.
In some cases, our radiologist may ask you to come back for a follow-up examination such as a diagnostic mammogram to rule out any suspicious areas.
3D MAMMOGRAPHY: An additional screening tool
For decades, doctors have been searching for a technology to help them find very small cancers or rule out “false positives” and reduce the number of women who are called back for a diagnostic mammogram.
Scientists have developed a new technology called breast tomosynthesis (or 3D), which has been shown in clinical studies to be superior to digital mammography.
Breast tomosynthesis (3D) allows doctors to examine breast tissue one layer at a time. This exciting new technology is leading the way in the fight against breast cancer. Breast tomosynthesis may be used in conjunction with traditional digital mammography as part of your annual screening mammogram to capture more breast images. Very low X-ray energy is used during the screening examination so your radiation exposure is safely below the American College of Radiology (ACR) guidelines. Using breast tomosynthesis and digital mammography together for screening has been proven to reduce “call-backs”.
Breast tomosynthesis may also be used for a diagnostic mammogram if you happen to be called back for this type of exam.
