"Brain cancer incidence and mortality have been increasing in many industrialized countries," said Tongzhang Zheng, associate professor of epidemiology and environmental health at Yale School of Medicine and principal investigator of the study published in a recent issue of the journal Cancer Epidemiology, Biomarkers & Prevention. "Some have suggested that cigarette smoking and other tobacco product use may increase the risk of brain tumors because tobacco product use is considered to be the greatest source for human exposure to N-nitroso compounds, which are potent nervous system carcinogens in animal studies. Our investigation, however, did not find a positive association between cigarette smoking, or with use of other tobacco products, and risk of brain cancer."
