Can I have breast reduction to become flat chested?

In order to make you flat chested, you would likely require a free nipple graft breast reduction that involves removing the nipples completely, performing the reduction, and replacing the nipples as a skin graft.  When performing a standard breast reduction, we are limited on how small we can make a patient's breast because we have to keep enough breast tissue to keep the blood supply to the nipples intact.  Two of the large drawbacks to performing a free nipple graft breast reduction is guaranteed loss of nipple sensation and ability to breast feed in the future.  You do not have to make a patient flat chested to dramatically improve back/neck/shoulder discomfort and rashes under breasts.  You will likely be very pleasantly surprised how much your symptoms improve with a standard breast reduction.  Basically think of how much easier it is to carry a half gallon of milk against your chest than a full gallon of milk with your arms stretched straight out as an analogy.  I wish you the best with your plastic surgery journey!

It sounds like you are talking about almost having a mastectomy. While this can be done, it is not recommended.
