| Frequently
Asked Questions: Mammograms
 What
are the benefits of screening mammography?
Today’s high-quality screening mammography is the most effective tool
available to physicians in detecting breast cancer before lumps can be
felt or symptoms of cancer appear. Early detection of breast cancer not
only helps provide a woman with more options, but also increases the
possibility of a favorable prognosis.
Is there a risk of radiation exposure from having regular
mammograms?
The risk of harm from radiation exposure is extremely small, and the risk
decreases significantly as a woman ages. The actual exposure of radiation
during a mammogram is about equivalent to that of having a dental exam.
The US Food and Drug Administration (FDA) regulates that mammograms not
exceed 2 rads (radiation absorbed dose), the unit of measure for radiation
exposure. Most mammograms actually deliver a small fraction of that amount
and a woman must carefully weigh the risks of not having mammograms
against that of this small radiation exposure.
What should a woman expect when having a mammogram?
A woman should avoid using deodorant and lotions and wear two-piece
clothing on the day of her mammogram. A specially-trained radiological
technologist, who will perform the x-ray, will ask the woman to undress
and stand next to the x-ray machine. Two flat surfaces, or plates, are
lowered and compress each breast for a few seconds. This compression is
necessary to produce the best pictures using the lowest amount of
radiation 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 one week after your menstrual period. If you do experience
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 65 and 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.
