Digital Mammography and 3D Mammography

What is Mammography?

Mammography is an X-ray technique used to visualize the internal structures of the breast. Approximately 2 million women in the United States have mammograms each year. Mammography performed by an accredited and FDA certified mammographic imaging provided is the most reliable method currently used to detect breast cancer and compliments physical examination for screening women who have no symptoms. Our mammographic imaging program is FDA certified and as such follows all FDA guidelines. These guidelines include the proper use of breast compression, which increase the visibility of the small details in the image, and reduces the amount of X-ray radiation needed to produce the image.

What is the difference between a traditional 2-D Mammogram and a 3-D Mammogram?

We now offer 3-D Mammograms, also called tomosynthesis. 3-D Mammograms use the same X-ray technology and method as a 2-D Mammogram but there are some differences. With 2-D Mammograms images are only taken from the front and side and the advanced 3-D imaging takes many pictures from several angles. A computer then produces a 3-D image that can be sliced and scrolled through, like pages in a book. This means that the radiologist can examine your breast tissue layer by layer and makes it easier to find potentially worrisome abnormalities.

When and where will the mammography be done?

DMS Mobile Imaging Service performs Digital Mammograms at North Valley Health Center every other Wednesday.

How long will the Mammogram take?

The exam will last approximately 20 minutes. We ask that you check in at the reception desk 10 minutes prior to your exam.

How safe is Mammography?

Mammography is very safe. Radiation exposure during the mammogram is extremely low. The procedure involves no injections or invasive procedures.

Will insurance cover a Mammogram?

Most insurances cover Mammograms. However, it is best to call your insurance in advance to see if a 3-D Mammogram will be covered. If you wish to not have a 3-D Mammogram or if your insurance doesn’t fully cover them, 2-D is still available.

Breast Care Screening

A complete breast care program includes monthly breast exams, and mammograms.


Checking your breasts is called a breast self-exam. You should examine your breasts every month, about one week after your menstrual period ends. If you do not have regular periods, examine your breasts on the first day of each month.


This is a breast exam by your health care professional to make sure you haven’t missed anything during your breast self-exams. This is a good opportunity to ask any questions you want and to request a demonstration of breast self-exam, if needed.


A mammogram is the most effective way to detect breast lumps too small to be felt or seen. It usually consists of two or more low-dose X-rays. Mammography is not painful, although it may feel slightly uncomfortable because the breast is compressed for a few moments.
