Delhi doctors see GI cancer patients as young as 15; could air pollution be a hidden risk?
Oncologists in Delhi are observing an increase in gastrointestinal cancer cases among teenagers, prompting researchers to investigate potential links to air pollution. While studies show a statistical association between PM2.5 exposure and cancer mortality, experts caution that a direct causal link for these specific cases has not been proven.
