We have recently shown that exposure of hamsters to N-nitrosodiethylamine and hyperoxia causes a high incidence of this tumor type. In this study, we show that the tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone also causes neuroendocrine lung tumors in hyperoxic hamsters. Animals m...
