The Ohio Cancer Incidence Surveillance System (OCISS) collects and analyzes cancer incidence data on all Ohio residents. Cancer incidence is defined as newly-diagnosed cases of cancer. All Ohio providers of medical care are required, by law, to report to OCISS all cancers diagnosed and/or treated in Ohio. Cancer is diagnosed each year in more than 60,000 Ohioans and costs billions of dollars in medical expenses and lost productivity.
The collection and analysis of population-based cancer incidence data help determine the burden of cancer in Ohio’s communities, raise awareness about factors that may increase cancer risk and the benefits of early detection, and improve the survival of persons diagnosed with cancer. Ohio’s cancer incidence data are widely used by public health professionals, medical researchers and others to develop, implement and promote many cancer prevention and control activities in Ohio and to support important cancer-related research.
