Thyroid cancer incidence in women and proximity to industrial air pollution sources: A spatial analysis in a middle size city in Colombia

Ecological regression models showed that, for women, smoothed standardized incidence ratio (sSIR) increase in 15% [95% credibility interval: 3-27%] and 63% [95%CI: 18-125%] per one standard deviation increase in EI for dichloromethane and PCDDs/Fs, respectively. Point-data analysis confirmed a cluster of female cases close to an industry emitting chlorinated solvents. These results suggest that dichloromethane and PCDDs/Fs emitted from industrial sources might be suspected as thyroid cancer risk factors.
