What is a mammogram?

Mammography is a specific type of breast imaging using a low dose x-ray. It shows the glands, fat and blood vessels of the breast and can find abnormalities in your breast that are too small for you to feel yourself.

 

Understanding your mammogram

Mammography can detect tiny changes in your breasts which you may not have noticed. These changes may be due to cancer and may be smaller than a grain of rice. 90% of breast cancers are detected by mammography. Early detection and treatment of small cancers greatly increases your chances of a better prognosis.

 

On the day of your mammogram:

  • When you arrive, please check in with reception. We’ll make sure your details are correct and ask you to complete any appropriate consent forms. 
  • Please do not use talcum powder or deodorants on the day of your examination as they can show up on the mammogram images.
  • If your breasts are tender or sore before your period, you should try to arrange to have your mammogram just after your period finishes
  • You will be asked to undress from the waist up and put on a gown. 
  • Your visit should take approximately 30 minutes. Please allow plenty of time.

 

During your mammogram:

  • Your mammogram will be performed by a Medical Imaging Technologist (MIT) with specialised training and experience (mammographer). 
  • Two views of each breast are taken, however sometimes further views are required so that all the breast tissue can be clearly demonstrated. There is no need to be concerned if this happens, as we are simply being thorough. 

 

After your mammogram:

  • You can resume normal activities after your mammogram.
  • The images will be interpreted by a radiologist, and your report will be sent to your referring clinician. 

Frequently asked questions

Yearly mammograms are recommended for women 40 – 50 years of age. Women over the age of 50 years should have mammograms every two years (some women may wish to continue with annual mammograms for personal choice). It may be appropriate that women with a family history of breast cancer start mammography at an earlier age or have an annual mammogram. 

If you have any breast concerns, you need to see your GP. Your GP will refer you for the appropriate diagnostic breast imaging service.

Common signs requiring further investigation by your doctor include:

  • A thickening or a lump
  • Skin dimpling or ulceration
  • Nipple discharge
  • Persistent nipple rash
  • Focal pain
  • Change in breast shape or size

A support person may accompany you to your appointment but typically cannot enter the scan room.

It is best not to bring children unless someone can supervise them during your scan.
