People with a higher Body Mass Index (BMI) – i.e., those who are heavy for their height – are at lower risk of lung cancer. However, the effect of BMI on those who do develop lung cancer is less understood. A recent study found that among patients with advanced non-small cell lung cancer (NSCLC), those who were obese had higher survival rates early in the study than normal-weight or merely overweight patients. However, after 16 months on the study, the survival rates of obese patients dropped below those of other patients. Over time, the risk of death from other causes that obesity poses appears to outweigh the protective effect of high body weight against death from lung cancer.
