Who qualifies for lung cancer screening under current guidelines
Lung cancer screening can reduce deaths by 20%, according to a thoracic surgeon at Yale University.
Current US guidelines recommend an annual low-dose CT scan for people aged 50 to 80 who smoke now or have a significant smoking history.
Early-stage lung cancer often has no symptoms, though a persistent cough, shortness of breath or coughing up blood can occur.
There is no set screening guideline for people who never smoked, although those with a direct family history of lung cancer and some higher-risk groups may consider annual scans.
People should discuss the scan’s benefits, limits and possible harms with a health care provider; screening may not suit those unlikely to live long enough to benefit or receive treatment.
Doctors expect clearer guidance for never-smokers within a year or two, while one surgeon hopes blood tests could help determine who needs a CT scan in four or five years.
Current guidelines recommend annual low-dose CT scans for people aged 50 to 80 who currently smoke or have a smoking history of at least 20 pack-years.
People with serious health problems likely to limit their lifespan, or who could not receive treatment if cancer is found, should not be screened, according to the American Cancer Society.
There is no set screening guideline for people who have never smoked.
Daniel J. Boffa said people who never smoked but have a direct family history of lung cancer should consider annual screening.

What people are saying
one of the most powerful ways
It reduces the chance of people dying of lung cancer by 20%
I would anticipate that in the next year or two, we will have better guidance for people who are at risk for lung cancer, but never smoked
