Oregon State Cancer Registry (OSCaR)

Cancer is a Reportable Disease in Oregon


Every year, thousands of Oregonians are diagnosed with cancer. The Oregon State Cancer Registry (OSCaR) was established in August 1995, after the Oregon Legislature unanimously passed legislation making cancer a reportable disease.

OSCaR is a statewide, population-based registry that collects and analyzes information about cancer cases occurring in Oregon. The mission of the Oregon State Cancer Registry is to collect complete, quality cancer data that supports cancer research and public health practices designed to improve efforts in the screening, treatment and survivorship of all people in Oregon affected by cancer.
