(St. Louis) -- A professor at Washington University's School of Medicine says low-doses of estrogen can help control metastatic breast cancer.
Dr. Mark Ellis found that about a third of participants in a study of breast cancer patients had their tumors stop growing or even shrink.
Ellis says low-dose estrogen therapy is a natural treatment for breast cancer and is much cheaper than chemotherapy, costing less than a dollar a day.
Ellis released the study at the 31st annual San Antonio Breast Cancer Symposium.
