Experiments were conducted to study the tumor response of hamster tracheas to N-nitroso-N-methylurea. Tracheas were exposed repeatedly with the use of a tracheal catheter. Ten to 30 exposures were given over a period of 5 to 20 weeks. The carcinoma incidence (including carcinoma in situ) was 0,42, 67, 88, and 94% for 10, 15, 20, 25, and 30 twice-weekly exposures, respectively. With 10 exposures...
