Congratulations to Dr Stephen Choi, a postdoctoral cancer researcher in the Urologic Sciences Department at the University of British Columbia, who is earning the Mitacs Award for Outstanding Innovation — Postdoctoral for his work to develop a groundbreaking treatment for prostate cancers. Turning conventional wisdom on its head, Choi discovered that suppressing lactic acid, a byproduct generated by cancer cells, can prevent cancer from spreading. His work is now being used to develop an innovative, low-cost drug therapy.
