Outline of Research at the Start

Lung cancer in never smokers (LCINS) is an emerging public health challenge in Japan and globally. Current prevention efforts face significant knowledge gaps, particularly regarding gender- and histology-specific risk factors, partly due to fragmented data sources. This project addresses these gaps by developing an innovative data integration approach, employing advanced analytical techniques to explore LCINS risk factors comprehensively. The results will provide critical insights to support future strategies for lung cancer prevention, screening, and policy improvements in Japan.
