Nearly 5 million additional people are recommended to get screened for lung cancer under an updated guideline from the American Cancer Society, which expanded its recommendations to include older adults who smoke or formerly smoked — no matter how long ago they quit smoking.
Previously, the American Cancer Society recommended annual lung cancer screening for adults ages 55 to 74 with at least a 30 pack-year smoking history who either currently smoke or quit smoking less than 15 years ago. Now, the organization says how long ago you quit smoking should no longer be a factor in whether you get screened for lung cancer.
