|
• many tumors are large in size and well vascularized
|
• mice over 18 months of age show enhanced tumor formation in various organ
|
• liver cancer with bridging necrosis, dilated sinus, and congested vessels
• tumors also contain regenerative hepatocytes and active bile duct hyperplasia with mild cholestasis
|
• most uterine tumors are leiomyosarcomas which are well circumscribed but not encapsulated
|
• lung tumors have the highest incidence
|
• most lung tumors are adenocarcinomas in which the tumor cells have crowded, large, hyperchromatic nuclei
