  • Title: Morphological classification of mouse liver tumors based on biological characteristics.
    Author: Becker FF.
    Journal: Cancer Res; 1982 Oct; 42(10):3918-23. PubMed ID: 7104991.
    Abstract:
    Examination of three strains of inbred mice suggested that specific morphological types of hepatic tumors are the result of genetic predisposition while other types of tumors are associated with exposure to chemical carcinogens. A simple classification system is proposed. Additional studies indicated that a putative promoting agent, such as phenobarbital, increased the incidence of those tumor types usually associated with spontaneous appearance and only in strains with a genetic predisposition to spontaneous tumorigenesis. Carcinogens induce an increase in all types of tumors.
