Takeaways from Dr. Cohen’s “Advancements in Breast Imaging” Live Chat

Thank you to everyone who joined us for last week’s live web chat on “Advancements in Imaging for Early Breast Cancer Detection.” Dr. Michael Cohen, director, Division of Breast Imaging for Emory’s Department of Radiology, discussed the latest in breast imaging screening and technology.

Questions varied from ,“What are the current breast screening guidelines?” to “What is tomosynthesis and when is it the right choice for screening?” Below are just a few of the questions and answers from the chat. Make sure to view the chat transcript for the whole discussion.

Question: What are the current breast cancer screening guidelines?

Michael Cohen, MDAnswer:
Women aged 40 and younger should have a clinical breast exam at least every 3 years. All women aged 40 and over should get a yearly screening mammogram, clinical breast exam and perform a monthly breast self-examination.

 

Question:
When is breast tomosynthesis the right choice for screening? And how does tomosynthesis compare to an MRI in diagnosing cancer?

Michael Cohen, MDAnswer:
Digital Tomosynthesis (3D mammography) is an improvement on traditional 2D mammography. Rather than the traditional single view of a breast in 2D mammography, 3D mammography obtains a series of very thin 1 mm sections of the breast. This allows us to look at the breast as if we were viewing pages of a book and gives a much more accurate look inside. If tomosynthesis is available at your breast imaging facility, it is an excellent way to screen.

Studies have shown that 3D mammography permits detections of more cancers, while at the same time reducing the number of unnecessary call-backs to evaluate lesions that are not cancer. This is a win-win for the patient. MRI screening is reserved for a limited number of patients at high risk.

Question:
What about the radiation exposure for these types of test [tomosynthesis]; is it different from traditional mammograms?

Michael Cohen, MDAnswer:
With current technology, a patient receives both a 2D and a 3D mammogram at the same time. The addition of 3D about doubles the radiation exposure compared to 2D alone, but is still within FDA guidelines for mammography.

Also, some very exciting technology is on the horizon that will permit us to create a 2D mammogram from a 3D mammogram using sophisticated computers. When that becomes available, we will only need to do a 3D mammogram, thereby reducing the radiation exposure to the original level.

Advancements in Imaging for Early Breast Cancer Detection

Advancements in Breast Imaging ChatBreast cancer is the most common cancer among American women, according to the Centers for Disease Control and Prevention (CDC). October is Breast Cancer Awareness month and the breast care specialists across Emory Healthcare want you to know the importance of screening and early detection.

The American Cancer Society recommends that women (without breast cancer symptoms), age 40 and older should have a mammogram every year as long as they are in good health. Getting yearly screening mammograms increases the chance of detecting cancers in the early stages, before they start to cause symptoms. By detecting cancer early, screening exams also help increase the chance of survival and lower the risk of mortality.

At Emory Healthcare, we are proud to offer patients with leading breast screening techniques, including the latest in breast imaging technology, called tomosynthesis, or 3D mammography.

Learn more about breast screening guidelines and advancements in breast imaging by joining us on Tuesday, October 21 at 12:00 pm EST for a live web chat on “Advancements in Imaging for Early Breast Cancer Detection.” Dr. Michael Cohen, Director, Division of Breast Imaging for Emory’s Department of Radiology, will be available to answer questions such as: what is the latest in breast imaging technology? When should I start getting screened? To register for the chat, click here.

Also, during October, the Emory Breast Imaging Centers are offering extended and weekend hours for women needing a screening mammogram. Dates and details are below:

Extended Hours: Thursday, October 9, Tuesday, October 21, Thrusday October 23; 7:30 a.m – 7:00 p.m. at the Emory Breast Imaging Center on Clifton Road.

3D Mammography: A New View on Breast Cancer Prevention

3D Mammogram vs 2D mammogramBreast cancer ranks as the second leading cause of cancer-related death among women in the U.S., behind lung cancer, according to the American Cancer Society.

However, the ACS also notes that the rate of deaths caused by breast cancer has been declining since the late 80s, with larger decreases in women younger than 50. The trend is attributed to increased awareness, improved treatments and earlier detection through screening.

Mammograms, which were introduced in the 70s and have transitioned from film to digital, are still the only screening tool approved by the Food and Drug Administration (FDA).

No technology is perfect, and mammograms can miss some breast cancer cases. Since research has found that early detection significantly enhances the success of breast cancer treatment, the healthcare industry is in constant pursuit of better ways to see inside the breast.

Enter 3D mammography. Also called breast tomosynthesis, this relatively new breast imaging technology was approved for use in combination with conventional 2D mammography by the FDA in 2011.

“Breast tomosynthesis allows us to see the inside of the breast from many different angles, and it also gives us the ability to view breast tissue layer by layer, in 1 millimeter increments, or slices,” says, Dr. Maria Piraner,  breast imager (radiologist) for the Center for Breast Care at Emory Johns Creek Hospital.

During a 3D mammogram, the X-ray arm of the mammography machine passes over the breast in a slight arc, taking numerous low-dose images at multiple angles. A computer software program then combines those images into a 3D rendering of the entire breast. For patients who have had previous mammograms, the procedure is nearly identical to conventional mammograms, except each compression takes about 4 seconds longer.

3D mammography does not replace conventional 2D mammography; rather, the two procedures are done in combination on the same machine. The addition of the 3D component can help reduce the chance that a patient will need to be called back for additional images. Since conventional 2D mammograms produce single, flat images of the breast, a cancer can sometimes hide in the overlapping tissue, or overlapping tissue can give the appearance of an abnormality that isn’t there.

While women 40 and older should have a screening mammogram every year for as long as they are healthy, the choice to add 3D to their conventional 2D mammogram depends on personal factors, such as:

  • Family history of breast cancer
  • Having a high risk factor for breast cancer
  • Frequency of call backs on previous mammograms
  • Having dense breast tissue

Dr. Piraner says the advantages of the combination 2D/3D mammogram are:

  • Fewer patients need to be called back for additional images
  • Allows radiologists to see cancers when they are smaller and less complicated to treat
  • Is particularly useful for patients with dense breast tissue
