The Colorado Cancer Plan has guided the prevention, treatment and control of cancer statewide for more than 20 years. The 2016-20 state cancer plan continues in that tradition, providing a five-year framework to reduce the risk, incidence and mortality associated with cancer in Colorado. This plan represents a shared approach to over-coming Colorado's cancer challenges through primary prevention, early detection, effective treatment and support for survivors from the time of diagnosis until the end of life.
