| Outline of Final Research Achievements |
Breast cancer has a high incidence in our country and its control is urgently needed. The tupai is a small mammal with genetic information similar to that of humans. Since mammary tumors in tupai have a structure similar to that of human papillary adenocarcinoma, it was expected to be an excellent model for the development of breast cancer. Histopathological examination of spontaneous mammary tumors in Tupai revealed that the mammary gland tumors were often ductal papillary carcinomas, and that the morphology and pathology of the tumors were very similar to those of human papillary adenocarcinomas. Cytological examination confirmed that the tumor was an epithelial malignant tumor.
