 New federal guidelines have nearly doubled the number of Americans eligible for lung cancer screening. Insurance companies are required to cover these tests for those ages 50 to 80 who currently smoke or used to smoke. Along with new treatments, lung cancer screening saves lives. If you are 50 to 80 years old and smoke or used to smoke, talk to your doctor about lung cancer screening. For more information and to find a screening center near you, visit the National Lung Cancer Roundtable at nlcrt.org.
