Summary

This study looks at 248 lung cancer patients having surgery to see if the length of time they quit smoking before the operation affects their risk of complications like pneumonia or heart issues. Researchers compare recent quitters and long-term nonsmokers to find the best timing for quitting. The goal is to give clear advice on when to stop smoking to improve recovery after lung cancer surgery.
