 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 report it, just like bilateral mastectomies for their high family risk or have some mutation and then get their prostheses or they just get enhancements so they get like bilateral prostheses, 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 often unsolicited but my unsolicited recommendation to patients looking for augmentation is that retro pectoral 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 displaced. So on top of the pecs you're saying that it does impair but if you get augmentation below, you get it under the pecs.
