 if somebody was to opt for bilateral breast implants, and I know there's two situations somebody may get for whatever reason if they can afford it, just like bilateral mastectomies for the high family risk or have some mutation and then get their prostheses, or they just get enhancements so they get like bilateral prostheses, you know size A, how much literature-wise does that reduce the chance of finding a breast cancer? Let's say they didn't get mastectomies, they just had augmentation bilaterally, is it pretty significant? So my recommendation is that retropectoral implants do not obscure tissue in most women, so your pre-pectoral implants, that's the one that's in front of the muscle, we do know that does significantly impair the ability to perform the mammogram, because in women with implants we're getting minimum four views per breast, we're getting one with the implant in view and one with the implant displays.
