I had a double mastectomy (cancer only on one side), chemo and radiation. I will soon be having my exchange surgery. I am scheduled for the gummy bear implants with a doctor authorized to use them under the study. I will be a medium B cup but I'm not sure which of the three profiles to choose from. Does anybody have any feedback to help me understand the differences? Additionally, a friend who had the same doctor had the gummy bears and didn't like them and, after 6 months or so, she exchanged them for regular silicone. I need some help and direction. Thank you.
