Mammogram

How It Feels

A mammogram is often uncomfortable but rarely extremely painful. If you have sensitive or fragile skin, or a skin condition, let the technician know before you have your exam. If you have menstrual periods, the procedure is more comfortable when done within 2 weeks after your period has ended.

The X-ray plate will feel cold when you place your breast on it. Having your breasts flattened and squeezed is usually uncomfortable. But it is necessary to flatten out the breast tissue to obtain the best pictures.

Risks

A mammogram may help find cancer early. But finding cancer early doesn't always save lives. In some cases the cancer will have already spread to other parts of the body.

A mammogram may appear to detect a cancer even when a cancer is not present (false-positive results). This can occur at any age but is more likely with younger women. False-positive results can lead to emotional distress and unneeded tests and treatments.

A mammogram may miss finding breast cancer even when it is there (false-negative results). This is more likely to happen with young women who have dense breasts. False-negative results can keep a woman from getting treatment and can give her a false sense of security.

Also, mammograms may find certain types of breast cancer that would never cause symptoms or threaten a woman's life. But doctors cannot tell what kinds of cancer will cause problems, so all cancers are treated. This means that women may end up having tests and treatments they don't need. These can cause harm.

There is always a slight risk of damage to cells or tissue from being exposed to any radiation, including the very low levels of radiation used for this test. But the risk of damage from the X-rays is very low compared with the potential benefits of the test.

Results

A mammogram is an X-ray of the breast that is used to screen for breast cancer. Mammogram results are usually available within 10 days. It is not uncommon to be asked to return for another test so an additional view of an area in question can be obtained.
