The simple answer to the risk of losing sensation in the breast and nipple is that your chances of this are very low, somewhere between 1-2%. The incision is made in an area that doesn’t have any sensory nerves as a precautionary measure to minimize any potential risk to loss of sensation. Furthermore, the breast tissue itself is not cut. It is moved aside so that a space can be created for the implant, and then the implant is placed in the newly created opening. There have been some cases where sensation has been increased with the nipple and areola due to the implant pushing them forward.
