mortality/aging
• most mice die by 11 to 12 weeks of age due to overgrowth of the poorly differentiated and invasive carcinoma and lung metastases
• all mice die prior to 18 weeks of age

neoplasm
• mice develop progressive parotid gland carcinomas beginning after 3 weeks of age that occur earlier in male mice
• by week 3, female mice exhibit multifocal hyperplastic foci that progress into in situ lobular carcinoma and invasive carcinoma in mice that survive beyond 14 weeks of age
• mice exhibit lung metastases

endocrine/exocrine glands
• mice develop progressive parotid gland carcinomas beginning after 3 weeks of age that occur earlier in male mice
• by week 3, female mice exhibit multifocal hyperplastic foci that progress into in situ lobular carcinoma and invasive carcinoma in mice that survive beyond 14 weeks of age

digestive/alimentary system
• mice develop progressive parotid gland carcinomas beginning after 3 weeks of age that occur earlier in male mice

integument
• by week 3, female mice exhibit multifocal hyperplastic foci that progress into in situ lobular carcinoma and invasive carcinoma in mice that survive beyond 14 weeks of age

respiratory system

growth/size/body
• mice develop progressive parotid gland carcinomas beginning after 3 weeks of age that occur earlier in male mice
