Mammography is a safe, low-dose x-ray picture of the breast that allows early detection of breast cancer. Specific CDI locations offer screening and/or diagnostic mammography. In a screening mammogram, images are taken of each breast from two angles. A diagnostic mammogram may take longer as it requires more images and different angles to rule out any abnormalities, or under special circumstances such as breast implants.

Exam preparation

• A CDI representative will call you prior to your appointment to provide specific instructions, and review health and insurance information.
  
• Do not use deodorant, talcum powder, or lotion under your arms or near your breasts on the day of your mammogram.
  
• Wear a two-piece outfit so you will have to remove only your top.
  
• Notify a member of CDI’s staff if you are nursing of if there is a chance you could be pregnant.
  
• Bring with you the name, address, and phone number of any facility where you have had a prior mammogram and bring previous films. (The radiologist needs your previous films for comparison in order to make an accurate assessment. Failure to bring your films may result in a delay of the physician's report.)
  
• Please arrive 15 minutes early to verify your registration.

During your exam – what to expect

• You will be positioned in front of a special x-ray machine, warmed for your comfort.
  
• One at a time, each of your breasts are pressed momentarily between an adjustable platform and a clear plate. Some brief pressure is necessary to flatten the breast in order to get the clearest picture.
  
• The entire exam typically takes about 10-15 minutes.

What happens after the exam?

• A radiologist who specializes in breast imaging will review your mammography pictures. The radiologist prepares a diagnostic report to share with your doctor.
  
• Your doctor will consider this information in context of your overall care, and talk with you about the results.
