Abstract: Much literature acknowledges the importance of political systems for population health. People living in democratic countries tend to have higher life expectancies and lower rates of infant mortality compared to those in other countries. However, few quantitative comparative studies explore the political origins of chronic disease. To address this gap, this study examines the impact of political democracy on cancer risk. Using data from the Global Cancer Observatory (GLOBOCAN), regression models test differences in age‐adjusted cancer rates across 170 countries. Counter to study hypotheses, overall incidence of cancer is not any lower in democratic countries. This is evident even when removing the confounding influence of economic and several other factors. However, among children and adolescents, cancer mortality rates and leukemia incidence are exceptions since these are lower in democratic countries in some models. Results otherwise do not support the view that political regime type alone prevents cancer. Overall findings appear robust to threats of endogeneity, higher average age in developed countries, comparative differences in the ability to diagnose cases, and several other threats. The broader literature indicates that democratic countries have better health overall. However, findings are that democratic countries have higher cancer incidence on average, which is likely due to having higher levels of economic prosperity compared to more autocratic countries. Economic policy is likely to be an important consideration for preventing cancer. Longitudinal analysis was not possible for these data, which is reason for caution when interpreting these findings.
