Diallylnitrosamine: a potent respiratory carcinogen in Syrian golden hamsters: brief communication.

Diallylnitrosamine (DAN), one of the few nitrosamines tested thus far that has not induced neoplasms in rats, caused a high incidence of respiratory tract tumors in Syrian golden hamsters treated sc with single or weekly doses of the compound. The effect was dose-dependent. The nasal cavity, larynx, and trachea were the most affected by DAN; most drug-induced tumors at those sites were adenocarcinomas and papillary polyps.
