Frequently Asked Questions about Mammography

What are the benefits of screening mammography?

Today's high-quality screening mammography is the most effective tool available to doctors for detecting breast cancer before lumps can be felt or symptoms of cancer appear. Early detection of breast cancer not only helps provide you with more options, but also increases the chance of a good prognosis (outlook).

Is there a risk of radiation exposure from having regular mammograms?

The risk of harm from radiation exposure is extremely small. The risk decreases as you get older. The actual exposure of radiation during a mammogram is about equivalent to that of having a dental x-ray. The U.S. Food and Drug Administration (FDA) regulates mammograms so that they do not exceed 2 rads (radiation absorbed dose), the unit of measure for radiation exposure. Most mammograms actually deliver a small fraction of that amount. You must carefully weigh the risks of not having mammograms against the risk of this small radiation exposure.

What should I expect when having a mammogram?

On the day of your mammogram, wear two-piece clothing, and do not use any deodorant or lotions. A specially trained radiation technologist will perform the mammogram. This person will ask you to undress and stand next to the machine. Two flat surfaces, or plates, are lowered. They compress your breasts for a few seconds. This compression is necessary to produce the best pictures using as little radiation as possible.

Are mammograms painful?

Some women find the pressure of the plates on their breasts to be uncomfortable or even somewhat painful. Timing your mammogram when your breasts are not tender is important. In premenopausal women, this is usually 1 week after your menstrual period. If you do have discomfort or pain, remember that each x-ray takes just a few moments and could save your life.

Who pays for mammography?

Medicare covers mammography screening for women aged 65 or older every year. Most states now require that health insurance policies offer mammography screening reimbursement. In addition, many mammography facilities also offer special programs and lower fees during National Breast Cancer Awareness Month in October.
