This news is based on the following article: Jones RR, DellaValle CT, Weyer PJ, et al. Ingested nitrate, disinfection by-products, and risk of colon and rectal cancers in the Iowa Women's Health Study cohort. Environ Int 2019 ; 126 : 242-51. doi : 10.1016/j.envint.2019.02.010
This analysis of data from a huge cohort of women in Iowa (USA) adds to the sparse literature on the link between colorectal cancer and exposure to nitrates and by-products of water disinfection. Its results suggest essentially that long-term exposure to trihalomethanes influences the risk of rectal cancer.
