COVID-19's lingering shadow: The molecular link between SARS-CoV-2 and lung cancer risk

A new study suggests that COVID-19 may slightly increase the risk of lung cancer by triggering a biological chain reaction in the lungs, driven by the virus's spike protein, that promotes inflammation, scarring, and tumor-friendly conditions, especially in higher-risk groups like smokers; while the individual risk remains small, the findings are important because they reveal a plausible mechanism and potential targets for prevention and treatment.
