[Diethylstilbestrol intervention in carcinogenesis of breast cancer in wistar rats].

Background & Objective: As a synthesized estrogenic drug, diethylstilbestrol (DES) is generally used to cure diseases like climacteric period syndrome and osteoporosis due to estrogen insufficient, but its effect on mammary gland epithelial cells is still unclear. This study was to observe the effect of DES on dimethylbenzanthracene (DMBA)-induced carcinogenesis of breast cancer in Wistar rats.

Methods: A total of 90 Wistar rats were equally divided into control, DES(1), DMBA, DES(1) plus DMBA, DES(2) plus DMBA, and DES(3) plus DMBA groups.
