Is it true that they remove tissue and fat during a breast lift?

Typically, a breast lift only has some skin removed, and all of the breast tissue is retained, as the goal of a breast lift is to keep all the volume, but reposition the breast to a higher position on the chest. A breast reduction has both skin and breast tissue removed because the goal is to reduce the size of the breast. Occasionally, depending upon the persons individual anatomy, small areas of breast tissue are removed with a breast lift in order to maximize the aesthetic breast shape. Best wishes.

Dear Cheerful141788,
in case of breast lift your surgeon will remove excess skin but will not reduce breast tissue. If you are considering surgery, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.
