Mammogram Testing for Breast Cancer

Mammogram Equipment

A mammogram is a test performed with a machine that is specifically designed to create detailed X-ray images of breast tissue using compression and small doses of ionizing radiation. Mammograms often reveal solid tumors, fluid-filled cysts and fatty masses that are otherwise unnoticeable, as well as clusters of calcium called microcalcifications that may or may not be cancerous. As such, a mammogram can be valuable for detecting breast cancer in its earliest stages, when more treatment options are usually available. For this reason, the multispecialty team in the Don & Erika Wallace Comprehensive Breast Program at Moffitt Cancer Center recommends annual screening mammograms beginning at age 40 for most women, and earlier for women who have a heightened risk of developing breast cancer.

There are two main types of mammograms:

  • A screening mammogram is a preventive measure used to check for possible signs of breast cancer in women who do not have any noticeable symptoms.
  • A diagnostic mammogram can be used to take a closer look at an abnormality or cellular change detected in a screening mammogram by producing additional images focused on a suspicious area.

In addition to standard mammography, which produces two-dimensional images, breast tomosynthesis can be used to create a three-dimensional mammogram, which can be especially helpful for evaluating dense breast tissue. During this test, a breast is compressed once while multiple low-dose X-rays are captured from many angles as the machine slowly moves around it. A computer then compiles the images to create a detailed, three-dimensional picture.

It’s important to keep in mind that the results of any mammogram alone cannot conclusively prove that a change in breast tissue is precancerous or cancerous. In fact, most of the abnormalities detected through mammography turn out to be benign (noncancerous). To make this determination, a physician will typically order additional testing, such as more detailed images produced by a breast ultrasound or magnetic resonance imaging (MRI). If further testing reveals a solid mass, a physician may recommend a biopsy to remove a small sample of cells from a suspicious area to check for the presence of cancer.
