Early Intervention Strategies for Lung Cancer

This trial is testing whether a structured early intervention strategy — including low-dose CT screening and follow-up care — can help detect lung cancer earlier in community health centers in Guangzhou, China. You may be eligible (as a patient) if: you are between 40 and 75 years old; you have lived in the study community for a long time; you have no known history of lung cancer and have not had lung cancer screening in the past 3 months; and you are willing and able to sign consent and participate in follow-up. You may NOT be eligible if: you have already been diagnosed with lung cancer; you have severe health conditions that make CT imaging unsafe; you cannot understand the study or give informed consent; or you are in another trial that may affect results. Talk to your doctor to see if this trial is right for you.
