Mammography Health Article

Definition

A mammogram is an x-ray picture of the breasts. It is used to find tumors and to help tell the difference between noncancerous (benign) and cancerous (malignant) disease.

Alternative Names

Mammogram

How the test is performed

You will be asked to undress from the waist up and will be given a gown to wear. Depending on the type of equipment used, you will sit or stand.

One breast at a time is rested on a flat surface that contains the x-ray plate. A device called a compressor will be pressed firmly against the breast to help flatten out the breast tissue.

The x-ray pictures are taken from several angles. You may be asked to hold your breath as each picture is taken.

Sometimes you will be asked to come back at a later date for more mammogram images. This does not always mean you have breast cancer. Rather, the doctor may simply need to recheck an area that could not be clearly seen on the first test.

Digital mammography is a newer technique that allows the x-ray image of the breast to be viewed and manipulated on a computer screen. It improves accuracy a little bit, but is not yet availabe everywhere.

How to prepare for the test

Do not wear deodorant, perfume, powders, or ointments under your arms or on your breasts on the day of the mammogram. These substances may obscure the images. Remove all jewelry from your neck and chest area.

Tell your health care provider and the radiologist if you are pregnant or breastfeeding.

How the test will feel

The metal may feel cold. When the breast is compressed, you may have some pain. However, this is necessary in order to obtain good images.
