Different Types of Mammograms


mammogram screening

There are a few different types of mammograms: there are screening mammograms, used to detect signs of breast cancer, and diagnostic mammograms, used to diagnose abnormal screening mammograms and visible breast cancer symptoms. Both screening and diagnostic mammograms can either be 2D (traditional) mammograms or 3D mammograms, also known as breast tomosynthesis. Learn more about the different types of mammograms below.

Screening Mammograms

  • Used to detect signs of breast cancer in women who have no symptoms
  • The x-ray images make it possible to detect tumors that cannot be felt
  • Should be performed annually at age 40 and older
  • After the test, a radiologist interprets the images and informs the patients of the results within 30 days
  • The current test is compared to previous ones to find tiny abnormalities
  • Most of the time, results are normal

Diagnostic Mammograms

  • Used to diagnose abnormalities found in a screening mammogram or when other symptoms have been found (lumps, nipple pain, discharge)
  • Takes longer to perform than a screening mammogram and the total dose of radiation is higher because more x-ray images are needed
  • A radiologist will be on hand to immediately interpret the results
  • Additional imaging may be necessary, such as an ultrasound or biopsy
  • Results are usually either (1) the abnormal trait turns out to be normal, (2) the abnormal area is not cancerous, but should be monitored, or (3) the abnormal area may be cancerous, and a biopsy is required

2-D Mammograms

  • Traditional digital mammogram
  • Flat, 2-D images
  • Can be limiting due to overlapping layers of tissue, which can sometimes produce unclear results, false alarms, or missed cancer signs

3-D Mammograms (Tomosynthesis)

  • A newer type of digital mammogram in which x-rays take pictures of thin “slices” of the breast from different angles which are then constructed into a 3-D image using computer software
  • Allows your radiologist to examine your breast tissue one layer at a time, resulting in a higher accuracy of breast cancer detection and lower callback rate
  • Better for women with dense breast tissue, since both dense breast tissue and cancer appears white on a mammogram; by viewing the breast as layers, a radiologist is better able to differentiate the two
  • No additional compression is required (same level of discomfort), but takes a few longer seconds for each view compared to 2-D mammograms
  • Can be more expensive than 2-D mammograms, but PURE Mammography offers 3-D mammograms at no extra cost
