BOSTON, Sept. 14 (UPI) -- U.S. scientists say they've found that in human breast cancer cell tumors in mice, a diabetes drug worked better than chemotherapy in prolonging remission.
Researchers led by Harvard Medical School Professor Kevin Struhl said the mice appeared tumor-free for two months after treatment before the end of the experiment. The drug, metformin, appears to selectively kill cancer stem cells in culture dishes and in mice.
