If you have breast implants, be sure to tell your mammography facility that you have them when you make your appointment. You will need an x-ray radiologic technologist who is trained in x-raying patients with implants. This is important because breast implants can hide some breast tissue, which could make if difficult for the radiologist to see breast cancer when looking at your mammograms. For this reason, to take a mammogram of a breast with an implant, the x-ray technician might gently lift the breast tissue slightly away from the implant.
