Why do you need to cut out the nipple and replace it further up to lift a breast?

Your concept that cutting out skin above the areola will lift the breast is not valid.  If the skin was capable of holding up your breast, you would not need a breast lift it the first place.  Instead, I recommend The Bellesoma Method.  This uses the excess skin to create an internal cone that transfers the weight of the breast to the underlying pectoralis major muscle.  This lifts the breast higher on the chest wall and provides a mechanically stable lift.  Vertical scars are avoided, nipple sensation and the ability to breast feed are maintained.Best Wishes,Gary Horndeski, M.D.

Your question is an excellant one. In most traditional breast lifts, or mastopexy, although there is a scar around the areolae, the nipple is not cut out,  actually, it just moves up with rest of the breast tissue that was sagging. This places it back more centrally on the breast mound where it should be. There are a number of techniques used to accomplish this goal. One could perhaps use a incision located above the breast to perform the procedure, however as you have noted ,this would leave a scar that is not readily covered by many types of clothes, including bathingsuits.

Neither the nipples nor the areolae need to be REMOVED during a breast lift revision.  A breast lift does involve MOVING the areola to a more superior position. The surgical incisions are strategically placed to be as minimally noticeable as is possible. 

Dear adnarim,
my preferred lift is a lollipop lift when a periareolar won't do (ie greater than 2cm lift required). The lollipop technique was created by a Canadian plastic surgeon named Elizabeth Hall-Findley and treats the breast as a three dimensional structure instead of two dimensions (anchor - lift). Most importantly it does not require the horizontal component scars that the anchor-lift requires and breasts appear much more natural, lifted, and less boxy. Lastly, the lift lasts longer because the lollipop doesn't rely on the skin to hold the breast up, its actually breast tissue thats being brought together to support the breast and hence improves longevity. 
If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

Many thanks for posting your question.You are right in principle, in that the techniques for breast lifts and reductions are all based on keeping any scarring below the level of the nipple.However, some of the scars in the lower part of the breast are also a result of techniques that help to re-shape the breast.I hope this answers your question!
