Lung cancer isn't obvious. In fact, symptoms often are subtle or nonexistent until it's too late.
People who smoke have the greatest risk for lung cancer, though it also can occur in people who have never smoked. Get answers and treatment sooner with lung screening and advanced diagnostic technology at Mayo Clinic Health System.
If you're current or former smoker age 50 or older, or have a personal or family history of lung cancer, or other know risk factors, you may benefit from screening.
