Endometrial evaluation by ultrasonography, hysteroscopy and histopathology in cases of breast carcinoma on Tamoxifen therapy.

Introduction: Tamoxifen, a nonsteroidal antiestrogenic agent, is used widely as adjunctive therapy for women with breast cancer. Most studies have found that the increased relative risk of developing endometrial cancer for women taking Tamoxifen is two to three times higher than that of an age-matched population. So we designed this study to assess the endometrial status in patients taking Tamoxifen for breast carcinoma.
