Estrogen tested as surprising weapon against aggressive breast cancer

NCT ID NCT03941730

Summary

This study is testing whether estradiol, a form of estrogen, can help control advanced triple-negative breast cancer that has a specific biomarker called ER beta. Researchers are giving estradiol pills to 8 postmenopausal women whose cancer has spread and seeing if their tumors shrink or stop growing. The trial aims to determine if targeting this specific biomarker provides a new treatment approach for this difficult-to-treat cancer type.
