The question you should probably ask is why should I quit smoking before breast reduction. I will assume you know all the reasons not to smoke in the long run such as lung disease, heart disease, arterial disease, etc. The reason plastic surgeons have concerns about smoking around breast reduction surgery is to try to limit your chance of complications. Smoking inhibits wound healing by decreasing blood flow to the tissues. During breast reduction surgery, the nipple is routinely moved and to do so the blood flow to the nipple as well as the breast skin is altered. Combine this with the negative effects of tobacco use, the risk of wound healing and nipple complications is significantly increased. Smoking is not good for you hearth and it is expensive. Seek out a smoking cessation program and do your best to stop. Good luck.
