Obesity increases lung cancer risk by weakening immune response

Obesity promotes lung cancer by suppressing the immune system's ability to fight tumors, a new study reveals. Researchers found excess abdominal fat impairs immune cells in the lungs, allowing early-stage lung cancer to grow unchecked. This contradicts previous research suggesting a lower risk for obese individuals. The study analyzed smokers and found higher abdominal fat correlated with increased lung cancer risk. This finding is significant as obesity rates in the U.S. continue to rise.
