A prospective cohort study found that quitting smoking after being diagnosed with early-stage non-small cell lung cancer may slow disease progression and decrease mortality.

The study is published in Annals of Internal Medicine.
How early is the course of COVID-19, mild or severe, determined? In Cell, researchers examined nasal cells sampled from patients at the time of diagnosis, looking for differences between those who developed severe disease and those who experienced a mild illness. Cells from patients who developed severe COVID-19 exhibited a more muted antiviral response. If the early stages of infection can determine disease severity, it opens a path for scientists to develop early therapeutic interventions.
