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.
