This study evaluates whether acupuncture at specific body points before and after surgery can improve sleep quality and reduce long-term postoperative pain in patients undergoing video-assisted thoracoscopic lung cancer resection. Eligible adult patients will be randomly assigned to receive either true acupuncture or sham (placebo) acupuncture in addition to standard care. Chronic pain will be assessed during hospital stay and up to 6 months after surgery.
