Natural large breasts are congenital or sometimes acquired as one one put on weight over time. Large breasts are normally saggy or droopy with large stretched nipples and they do not appear aesthetic. Large and heavy breasts will cause back and neck aches. They will cause bra strap tension and pain. Also the spaces between the breasts and the chest skin are prone to infections and often causes irritating itch and chronic skin changes.
Therefore reduction of the large breasts with reduction of the nipples and placing the nipple to their natural position can be considered because of all the trouble and problems.
However due to the complex shiftings of tissues there will be some degree of scaring but this can be managed with post-operative scar prevention to minimise these scars. For information most patients are most happy to get rid of their problems.
