Expanding the Risk Profile: Genetic Insights Into Lung Cancer in Non-Smokers

Guest: Paola Marignani, PhD, EMBA While smoking remains a key risk factor for lung cancer, up to 25 percent of cases occur in people who have never smoked, leaving significant gaps in our understanding of causation and diagnostics. Dr. Paola Marignani explores emerging discoveries in gene variants unique to never-smokers, uncovered through single-cell RNA sequencing and machine learning. Dr. Marignani is a Professor in the Department of Biochemistry and Molecular Biology at Dalhousie University in Halifax, Novia Scotia, and she spoke about this topic at the 2025 World Conference on Lung Cancer.
