Mammography
A 3D mammogram, also known as breast tomosynthesis, is an imaging test that uses a series of X-rays to create a 3D picture of the breast. The latest in breast health procedures, 3D mammography can be used for routine annual screening mammograms or for diagnostic mammograms to evaluate problems such as a lump or pain in the breast.
For many years, 2D digital mammography was the standard approach to breast imaging; however, 3D mammography has been proven to:
- Reduce false positives (when a test result incorrectly indicates cancer is present) by up to 40 percent, because of increased specificity and sensitivity of the detailed image
- Improve the detection of breast cancer by 10 to 30 percent
Screening mammograms: The American College of Radiology recommends screening mammograms beginning at age 40. Screening mammograms are for those who are not experiencing symptoms and are at average risk for breast cancer.
Certain factors impact your risk of breast cancer, including your medical history, age, ethnicity and family history. Talk to your doctor or other health care provider about the screening regimen that’s right for you.
Diagnostic mammograms: These mammograms are performed to diagnose changes in the breast. You may need a diagnostic mammogram if you have an abnormal screening mammogram or if you have breast symptoms (a lump, pain, discharge, rash, dimpling, or changes in shape, size, color or texture). Diagnostic mammograms provide more detailed images of the breast tissue and will give your provider additional information about the area(s) of concern.
If you are experiencing breast symptoms, please schedule an appointment with your provider for a physical exam first. They will then determine the most appropriate testing for you.
Self-schedule your 3D mammogram
Scheduling your screening mammogram is now easier than ever. As an established patient, you can now self-schedule your mammogram at our Covington, Gig Harbor, Olympia, Spokane, Tacoma and Yakima locations through your MyChart account, 24 hours a day, seven days a week.
Note: Diagnostic mammograms cannot be scheduled through MyChart. Please call to schedule your appointment.
Mammogram FAQ
-
-
Let us know if:
- You have had previous mammograms at other locations so we can compare them to your new images. You may need to request mammogram records directly from the previous facility.
- You are nursing or think you could be pregnant.
- You have breast implants. During your exam, we may need to use special positioning or take additional images.
- You’ve recently had a breast surgery or biopsy.
- You have a personal history of breast cancer.
- You have discovered a lump or are experiencing any other breast symptoms.
-
-
- Schedule your examination one week following your menstrual cycle.
- Eliminate coffee, tea or caffeinated products five days prior to your exam. Caffeine may increase breast sensitivity.
- Take a non-aspirin pain reliever such as Tylenol (acetaminophen), Motrin/Advil (ibuprofen) or Aleve (naproxen) one hour before your examination.

Your 3D mammogram will be performed by a certified technologist with advanced training in mammography. Before your exam, you will undress from the waist up, change into a gown, and remove any powder, deodorant or perfumes from your underarms and breasts using a towelette. Material in these products can interfere with accurate imaging of your breast tissue.

Typically, a routine screening mammogram consists of two views of each breast, one from above and one from the side. Images are obtained by compressing your breast tissue between a compression paddle and plate. Adequate compression is essential to detect subtle abnormalities and reduce radiation exposure. The compression may be briefly uncomfortable, especially if your breasts are tender. Most screening mammograms take approximately 15-30 minutes.

If your radiologist sees something abnormal on your screening mammogram, you will be asked to return for a follow-up diagnostic mammogram. A diagnostic mammogram is more detailed and may take longer than a typical screening mammogram. Depending on the results of the diagnostic mammogram, your doctor or other health care provider may order additional imaging such as an ultrasound or MRI.

A radiologist, a physician who specializes in interpreting medical imaging, will carefully examine your mammogram and any additional studies. The exam results will be sent to your health care provider and available through your MyChart account. A letter briefly explaining the results will also be mailed to you. It is important to follow up with your health care provider.
