Hi iiaz2015, For many women, the breast continues into the armpit region, without a distinct separation between the two. While this may be axillary breast tissue, it is equally likely to be extra subcutaneous tissue or fat. A breast reduction is typically performed in the face up position, allowing your surgeon access to everything under the armpit that can be reached with you lying flat on your back. An alternate strategy is to start a reduction in the facedown position, allowing a more extensive removal of the axillary and upper back fat, with the back scar leading to the scar underneath the breast from the reduction. The second paradigm, called the bra line lift, allows a 360 degree reshaping of the upper torso, as opposed to only operating on the breast. For insurance purposes, some insurances will cover breast reduction when certain criteria are met. Insurance will not cover the bra line lift extension. Hope this helps.
