Lung cancer screening can help detect cancer early, when treatment may be more effective. Thomas Varghese Jr., MD, explains who may benefit from screening, how smoking history and other risk factors affect eligibility, and what to expect from a low-dose CT scan. He also discusses the potential for false-positive results, why abnormal findings do not always mean cancer, and how experienced medical teams can help patients understand their results and make informed decisions about next steps.
