Correlation is poor between ultrasonographic measurements of endometrial thickness and abnormal pathology in asymptomatic tamoxifen users because of tamoxifen induced subepithelial stromal hypertrophy Other data suggest that low-risk and high-risk groups of postmenopausal patients may be identified before the initiation of tamoxifen therapy for breast cancer Although the concurrent use of progestin reduces the risk of endometrial hyperplasia and cancer in patients receiving unopposed estrogen, the effect of progestin on the course of breast cancer and on the endometrium of women receiving tamoxifen is not known. Increased endometrial changes, including hyperplasia, polyps, cancer, and uterine sarcoma reported; prompt investigation required if abnormal vaginal bleeding including menstrual irregularities, vaginal discharge, and pelvic pain or pressure in those receiving (or who have received) tamoxifen.
