No, you should wait at least a couple months after you quit breast feeding. This is not because of a risk of infection. There is always bacteria in your duct system (just like in your GI tract). It is because of the risk of galactocele.Think of your breast as a collection of grapes on the stem. There are about 20 breast lobules (grapes). They connect to the nipple via a duct system (the stems). While you are lactating, you produce milk in the lobule (grape) and send it via the duct (stem) to the nipple. The duct is just a hose connecting the lobule and the nipple. If you cut into the breast and through a duct and you are breast feeding, then milk will spill out of the duct (stem) and leak into the opened space in the breast where the incision was made. This is called a galactocele (or a collection of milk). It's not dangerous but takes some work to get to go away. Typically, you have to drain it and use medicines to stop the production of milk and then it heals. Theoretically, you could do a transaxillary implant while someone is breast feeding without the risk of galactocele. With the TA augment, the breast tissue is not incised and really never even touched. Practically, I still have patients wait after breast feeding before their breast surgery.Good luck.
