Mammography

What is a Mammogram?

Mammograms can detect breast cancers while they are very small, sometimes 2 years earlier than they can be felt by a woman or her doctor. A mammogram is an examination in which a low dose of radiation (an x-ray) is passed through the compressed breast. Compression of the breast tissue is necessary to ensure the highest quality image. Compression is not dangerous to your breast tissue, and any mild discomfort you experience should be temporary. "Routine" or "screening" mammograms are for patients without symptoms. If your mammogram is routine, a radiologist may not look at the mammogram before you leave the office. Sometimes the radiologist needs to clarify findings on the mammogram, and you may be asked to return for additional views or procedures soon after your initial screening. A follow-up exam may be scheduled 3 to 6 months after your mammogram. Follow-up is common and doesn't necessarily mean that cancer is suspected. "Nonroutine" mammograms are scheduled for patients who have known abnormalities or conditions, such as a lump, dimpling, or nipple discharge, for the first year following breast cancer diagnosis or breast surgery. If you are one of these patients, a radiologist reviews films before you leave, reducing the chance of being called back for additional views.
