Is It Possible to Transfer Breast Tissue from One Breast to the Other?

There are many operations in the realm of plastic surgery that are technically possible to perform, but do not fulfill practical considerations. This would be one of them. Apart from the technical challenges involved with this operation, there are also the oncologic factors that must me considered. Since breast tissue always harbors the ability to transform into breast cancer, you would not want to transfer it to any other part on the body.

Although conceptually it can be done it is not performed in practice. Rarely there is a salvage flap called the Cyclops flap(From the greek monster with one eye in the middle of the forehead because there is one  nipple in the center of the chest ) has been used for reconstructing radiation induced damage.  Nipples and areolas are also commonly shared. Otherwise breasts are not really used for reconstructing the opposite breast.

Technologically, this may be possible. However, as you have read by the multiple informative responses by the other plastic surgeons, there is no reason to do this, it would present with potential oncological risks (cancer), you would deform the donor breast and there are other options. If you are seeking a small amount of volume/deformity correction, fat injections would be reasonable.

Seek an opinion for your problem from a borad certified plastic surgeon.

It would be great to transfer breast tissue from one to the other, but technically this would be  predicament with breast cancer.

It is possible to perform breast enlargement by fat grafting (taking fat from another place on the body).  It would be better to take that fat from your abdomen or legs. Fat grafting is a new technique for breast augmentation and so far we have seen changes in mammograms which are easily identified as benign (not cancerous) but this has not been studied long term.  If you are young, you don't have much fat tissue in your breasts - they are more fibrous so it is difficult to use the other breast as a donor site for fat anyways.  Good luck!
