It is a surgical procedure done under general anaesthesia to reduce the breast size and also lift the breast. The excess breast tissue is mostly removed from the inferior half of the breast and the remaining breast tissue is stitched together which lifts breast as well as improves its projection. If only breast lift is desired then only excess breast skin is removed and tightened with minimum or no reduction in breast size. Both these procedures result in one vertical scar extending from the nipple to the breast fold and another scar around the nipple which is hardly visible.
This is the lollipop scar. In very loose breast an additional horizontal scar along the breast fold (anchor scar) may be required.
