註釋We investigate the relationship between cell phones and brain cancer using brain cancer death rates for 86 countries between 1990 and 2014 from the World Health Organization and country-level mobile phone subscription rates from the World Bank. We estimate difference-in-difference models including country and year fixed effects and time-varying country covariates. We find that mobile phone subscription rates are positively and statistically significantly associated with death rates from brain cancer 15-20 years later. As a falsification test, we find few positive associations between mobile phone subscription rates and deaths from rectal, pancreatic, stomach, breast or lung cancer or ischemic heart disease.
