My Breast Reduction Surgery is on the 28th of June (2017).
I prefer patients stopping at least 2-4 weeks prior to surgery and to stay off during the healing process. You are best to review this with your surgeon.
Most surgeons would want you to be completely off nicotine and cigarettes for at least 4 weeks prior to surgery. Reduction of blood flow to you nipple can lead to you losing that tissue. That is a nightmare for patient and surgeon. My advice is that you reschedule. Hope this helps.-JGH
