Abstract

A breast implant includes a shell fashioned from one of a group of materials which exhibit radiolucency at those x-ray in-tensities normally encountered for mammographic procedures. The radiolucent shell may be filled with radiolucent fill material as previously taught to thereby comprise a fully radiolucent breast implant.
The radiolucent breast implant enhances the use of mammography in detecting tumors in patients having breast implants to more effectively diagnose and treat cancer.
