Years after he quit smoking, a lung cancer scan saved his life

Key Points:

• Lung cancer remains the leading cause of cancer deaths in the U.S., with about 125,000 fatalities expected in 2024, despite declines in smoking rates and the availability of effective screening methods.
• Lung cancer screening with low-dose CT scans, recommended by the U.S. Preventive Services Task Force since 2013, significantly reduces mortality but is underutilized, with only about a quarter of eligible patients up to date on screenings.
• Screening eligibility criteria—such as age range, smoking history measured in pack-years, and smoking cessation within 15 years—are complex and contribute to low screening rates, alongside stigma and variability in insurance coverage.
• Experts and organizations like the American Cancer Society advocate for expanding screening eligibility by removing the 15-year cessation requirement to catch more cases early and improve survival rates, but the task force has yet to revise its guidelines.
• While screening and early treatment improve outcomes, quitting smoking remains crucial, as risk decreases the longer one abstains, but never fully returns to zero.
