What to Expect at Your Mammogram

After age 40, having periodic mammograms is one of the most important things a woman can do for her health. A mammogram is an X-ray of the breast. It can find changes in the breast when a lump is too small for you or your doctor to feel. Some women put off getting a mammogram because they think it will be painful, harmful or costly. But this screening is safe, quick and effective. And it could save your life.

How Does the Screening Work?

To be prepared, ask your health care provider to explain what will happen before you start the mammogram. In order to get a clear picture, a health care provider gently compresses each breast against an X-ray plate and takes the X-rays. The mammogram lasts only a few minutes.

You will feel some pressure and perhaps some discomfort during the mammogram. But most women find the exam does not hurt. If you are still having periods, schedule your mammogram a few days after your period ends. Your breasts are less sensitive at this time. There is a small but finite risk associated with exposure to radiation. 

What Happens if They Find a Lump?

If a mammogram shows a lump, you will need further tests to find out if the lump is cancerous. Like most tests, mammograms are not perfect. In some cases, the mammogram may find something that is not cancer. But getting the screening is worth it. Mammograms can find cancer at an early stage, when treatment is more effective.
