The short explanation
A mammogram is an X-ray of the breasts. You stand at the machine, and each breast is placed in turn between two flat plates that press it firmly for a few seconds while the picture is taken, usually from two angles. Many women find the pressing uncomfortable and some find it painful, but it lasts only seconds for each image, and the whole test usually takes under half an hour. The radiation dose is low. For women advised to have one, the benefit of finding a problem early is generally considered to outweigh this small exposure.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Booking for the week after your period, when breasts are less tender, can make it more comfortable. Avoid deodorant, powder or cream on the breasts and underarms on the day, as they can show on the image.
- Tell the staff if you could be pregnant, are breastfeeding, have implants or have had breast surgery.
- Sometimes you are called back for more pictures or an ultrasound. This is common and usually because an area needs a clearer view, not because cancer has been found.
- Government hospitals and some screening programmes offer mammograms at lower cost; it is worth asking your doctor where.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether a mammogram is right for you at this point. That depends on why your doctor suggested it, your history and your risk.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Why are you suggesting a mammogram for me now?
- Is this a screening test or are you checking a specific concern?
- How and when will I get the results?
- How often should I have one after this?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Book an appointment soon
- If the mammogram was suggested because of a lump or change, try to have it done within the time your doctor advised.
Raise it at a routine appointment
- Book the mammogram after your period if you can, and ask for a woman radiographer if that would help you feel at ease.
