Breast implants do not cause breast cancer, but they are linked to a rare type of lymphoma
Breast implants can certainly get in the way during a mammography, obstructing the view of breast tissue. This alone could lead to a misconception that they cause breast cancer, but it just means that they could prolong diagnosis.
If you have breast implants and are due to begin mammograms soon, let the facility know. They can provide additional screening so you can get the thorough care you need.
