Surgical Oncology Research

Surgical oncology is one of the integrated disciplines of the oncology service at Colorado State University. Research in this discipline involves retrospective studies, in vitro laboratory experiments, and clinical trials with client-consent. Many facets have been investigated (for the benefit of animal wellness and for improving human health), and our surgical oncologists collaborate with their colleagues from the other disciplines and from human medicine to make this a true integrated and translational approach.
