As we evaluated the smoking habits, we found that 102(41.6%) patients were smoker and 143(58.4%) patients were non-smoker at the time of diagnosis. Among the non-smoker group, only 31(21.7%) patients never smoked and 112(78.3%) patients stopped smoking before the diagnosis of BC. Of the 102 smokers, 34(33.3%) patients stopped smoking after diagnosis whereas 68(66.7%) patients were still smokers. The median smoking cessation time was 1.5 months ranging between 1 to 96 months. A total of 22(64.7%) patients were able to stop smoking in the first 6 months of the diagnosis. Postoperative smoking cessation times of each patient are shown in Figure 1.
