What is mammography?
Mammography is radiography or x-ray of the breast.
Mammography is referred to as
- screening mammography - this is a wellness check
- diagnostic mammography - breast xrays for a woman with a breast concern - a lump, thickness and / or pain.
Two x-ray views are taken when you undergo screening mammography: one downwards from the top of the breast and the other vertically from the side of the breast. In diagnostic mammography additional views to magnify the area of concern may also be taken.
Women are concerned about
- radiation ; The dose of radiation used is very low and less than you would get in a year from natural radiation
- compression : most women find the compression no more than uncomfortable. if you have had recent breast surgery, have breast implants, or found your last mammogram very uncomfortable please discuss this with the mammographer (specialist breast xray technician) prior to your examination as there are ways to help you manage the compression .
Why is it used?
Screening mammography is a wellness test and may detect breast problems before you have any symptoms or concern. Mammography may show changes in the breast up to two years before you or doctor can feel a breast lump, and this early detection of small breast cancers is important as it enables early treatment. Mammography can also be used as a way to diagnose an area of concern already identified by you or your doctor.
When should women undergo screening mammography?
Regular screening mammography is recommended for all women over 40 years of age.
- Women from 40-50 years should have annual mammography.
- Women over 50 years of age may continue to have annual mammography or opt to have two-yearly mammography. If you are unsure which applies to you, discuss this with your doctor.
- Women who have had a previous breast cancer should have annual mammography.
- Women who have a first degree relative (ie: their mother or a sister) who has had breast cancer, should start having mammograms five years in age before their relative was diagnosed.

You will be asked to take off your clothing from the waist up, and given a top to wear. For ease of undressing, you may like to wear a shirt and either a skirt or trousers.
Please don't wear deodorant or talcum powder on your breasts or armpits on the day of your examination. Discuss any breast symptoms or problems with the mammographer before the examination and bring along any previous mammography films to your appointment. It is important for the radiologists interpreting the mammogram to have previous studies for comparison as the Radiologist compares previous films with new images to look for any areas of change. Please remember to also bring the referral note from your doctor. |

The Examination |
|

A skilled mammographer will take at least two pictures of each breast. Each breast is placed on the x-ray machine and compressed with a plastic paddle. This flattening of the breast will reduce the breast thickness and hold the breast still, which optimises image quality and reduces radiation dosage.
Most women would describe the compression as uncomfortable, rather than painful. If you have found the compression painful, please discuss your concerns with the mammographer.
Sometimes further x-ray views may be needed to show an area of the breast more clearly. Don't be concerned if this occurs. An ultrasound scan may also be necessary to complete your examination.
Having a mammogram only takes about 20 minutes.
3 Post Examination
After the images are taken, you will be asked to wait until the mammographer has viewed them to see if any more are needed.
