Wear a two-piece outfit as you will need to undress from the waist up.

Do not use any perfume, deodorant, powder or ointment on your underarms or breasts as this can affect image clarity

 

What happens during my mammogram?

  • During the process, a female radiographer positions your breast between two flat plates and compresses it for a few seconds while an X-ray is taken.

  • The process is performed on one breast at a time.

  • You may experience some discomfort during the process. Be sure to inform your radiographer if you are in pain.

  • Try to relax and breathe calmly during the procedure.

 

How can I be more breast aware?

Monthly self-examination can improve your awareness of your own breasts and help to detect breast cancer early before it spreads.
