Low-dose CT (LDCT）can detect and treat lung cancer earlier and more quickly, while expanded screening coverage helps reduce the incidence and mortality of respiratory diseases such as lung cancer. This study aims to conduct a single-arm cluster randomized trial of digitally enabled LDCT in Guangzhou to assess its intervention effectiveness and cost-effectiveness.
The community health service center must be located within one of the 11 districts of Guangzhou.
Inclusion Criteria Aged 40-75 years. Residing in the community participating in the study for a long time. No known history of lung cancer and has not undergone lung cancer screening in the past three months.
Exclusion Criteria Individuals diagnosed with lung cancer. Individuals with severe other health issues that make them unsuitable for CT imaging.
