Mammography and breast implants
A woman who has had breast implants should continue to have mammograms. (A woman who has had an implant following breast cancer surgery should ask her doctor whether a mammogram is still necessary.) However, the woman should inform the technologist and radiologist beforehand and make sure they are experienced in x-raying patients with breast implants.
Because silicone implants are not transparent on x-ray, they can block a clear view of the tissues behind them. This is especially true if the implant has been placed in front of, rather than beneath, the chest muscles.
Experienced technologists and radiologists know how to take special care when compressing the breasts to avoid the danger of rupturing the implant. They can also use special techniques to detect abnormalities, sliding the implant backward against the chest wall, and pulling the breast tissue over and in front of it. Interpreting the mammogram can also be difficult, especially if scar tissue has formed around the implant or if silicone has leaked into nearby breast tissues.
