Your Guide to Mammogram Testing

Mammography is a screening test for breast cancer which uses special X-ray images to detect abnormal growths or changes in breast tissue.

Using a machine and X-ray film made especially for breast tissue, a technologist compresses the breast and takes pictures from at least two different angles, creating a set of images for each of your breasts. This set of images is called a mammogram. Breast tissue appears white and opaque and fatty tissue appears darker and translucent.

Why Do I Need a Mammogram?

The risk of breast cancer increases as women age. That is why it is very important for all menopausal women to get regular mammograms.

Mammography is your best defense against breast cancer because it can detect the disease in its early stages, before it can be felt during a breast examination. Research has shown that mammography can increase breast cancer survival.

Mammograms are performed as part of a regular physical exam or to evaluate any unusual changes in the breast.

A mammogram can help your doctor decide if a lump, growth or change in your breast needs further testing. The mammogram is also used to look for lumps or other findings that are too small to be felt during a physical exam.

How Often Should a Menopausal Woman Get Mammograms?

If you are over 40, you should get a mammogram every year or as recommended by your doctor. Sometimes your doctor will recommend starting earlier than age 40. This decision depends on your individual risk factors.

How Should I Prepare for a Mammogram?

Inform your doctor or the technologist performing the test if you are pregnant or think that you may be pregnant.

No dietary changes are necessary. Take your medicines as usual.

Do not wear body powder, cream, deodorant or lotion under your arms or on your chest the day of the test. These substances may interfere with the X-rays.
