Abstract: Low-dose spiral computed tomography (LDCT) screening for lung cancer reduced mortality in high-risk groups by 20.0%. The current screening criteria for high-risk groups have limitations and cannot be applied to non-high-risk groups. New specific screening strategies are needed. Now some companies put lung cancer CT screening as a benefit, regardless of age and other factors to do once a year, which is not only a waste of medical resources, but also harmful to physical and mental health. It is recommended to advance the time of the first baseline LDCT to near the age of 30 years, and to extend the follow-up interval from 2 to 10 years according to the findings of baseline CT combined with different age groups and other risk factors. A compromise screening strategy should be adopted for non-high-risk groups to detect lung cancer early and reduce CT radiation exposure.
