Thank you for the question.
Based on your description you may be a good candidate for breast reduction surgery; it tends to be one of the most patient pleasing operations we perform.
Some of the risks/potential complications associated with breast reduction surgery include: infection, bleeding, seroma, hematoma, wound healing problems, abnormal scarring ( hypertrophic or keloid), loss of sensation, inability to breast-feed, breast asymmetry, necrosis of tissue or skin, unsatisfactory cosmetic results, unpredictability of exact cup size postoperatively, recurrence of the breast hypertrophy, and the potential for further surgery. other risks related to surgery in general include deep venous thrombosis (clots), pulmonary embolism, pneumonia and even death.
Fortunately, the majority of patients who undergo this procedure by well experienced board-certified plastic surgeons and board certified anesthesiologists do very well and complications tend to be relatively minor and treatable. The severe complications are rare.
I hope this helps.
