A Low Selenium Level Is Associated with Lung and Laryngeal Cancers

It has been suggested that selenium deficiency is a risk factor for several cancer types. We conducted a case-control study in Szczecin, a region of northwestern Poland, on 95 cases of lung cancer, 113 cases of laryngeal cancer and corresponding healthy controls.). Selenium levels in the cases were measured after diagnosis but before treatment. We calculated the odds of being diagnosed with lung or laryngeal cancer, conditional on selenium level and genotype. with the risk of lung and laryngeal cancers.A selenium level below 60 µg/l is associated with a high risk of both lung and laryngeal cancer
