Lung cancer screening updates: Impact of 2023 American Cancer Society's guidelines for lung cancer screening.

• The 2023 ACS update removed the 15-years since smoking cessation requirement for lung cancer screening eligibility. • The updated guideline increases the number of eligible patients for LCS. • Up to 61.8% of our patients were LCS-ineligible due to not meeting the 15-year quitting timeline. • Immediate implementation of updated LCS guidelines is complicated. • Coordinated efforts by advocates and healthcare professionals are needed to improve LCS coverage under new ACS guideline.
