• mice die 14 weeks or less after tamoxifen administration

neoplasm
• at 6-8 weeks of age, animals administered 1dose or 4 doses of tamoxifen develop widespread adenomas in the alveoli by 14 weeks of age, but the bronchoalveolar duct junction remains tumor-free
• at 6-8 weeks of age, animals administered 1dose or 4 doses of tamoxifen develop widespread adenocarcinomas in the alveoli by 14 weeks of age

respiratory system
• at 6-8 weeks of age, animals administered 1dose or 4 doses of tamoxifen develop widespread adenomas in the alveoli by 14 weeks of age, but the bronchoalveolar duct junction remains tumor-free
• at 2 weeks after tamoxifen treatement, brochioalveolar duct junctions (BADJ) appear normal, but small adenomas occur in the alveoli; these progress to adenocarcinoma but the BADJ remain histologically normal
