Mammogram

A mammogram is done by a radiology technologist or mammogram technologist. The X-ray pictures (mammograms) are interpreted by a doctor who specializes in evaluating X-rays (radiologist).

You will need to remove any jewelry that might interfere with the X-ray picture. You will need to take off your clothes above the waist, and you will be given a cloth or paper gown to use during the test. If you are concerned about an area of your breast, show the technologist so that the area can be noted.

You usually stand during a mammogram. One at a time, your breasts will be placed on a flat plate that contains the X-ray film. Another plate is then pressed firmly against your breast to help flatten out the breast tissue. Very firm compression is needed to obtain high-quality pictures. You may be asked to lift your arm. For a few seconds while the X-ray picture is being taken, you will need to hold your breath. Usually at least two pictures are taken of each breast: one from the top and one from the side.

You may be in the mammogram clinic for up to an hour. The mammogram itself takes about 10 to 15 minutes. You will be asked to wait (usually about 5 minutes) until the X-rays are developed, in case repeat pictures need to be taken. In some clinics and hospitals, X-ray pictures can be viewed immediately on a computer screen (digitally).
