Cancer Intervention and Surveillance Modeling Network
(KAN-ser IN-ter-VEN-shun … ser-VAY-lents MAH-duh-ling NET-wurk)
A group of researchers supported by the National Cancer Institute (NCI) who use statistical models to help understand how cancer prevention, screening, and treatment programs can affect the number of new cases of cancer diagnosed each year and the number of deaths from cancer each year. The Cancer Intervention and Surveillance Modeling Network is now studying breast, colorectal, esophageal, lung, and prostate cancers. The models they create help guide future cancer control strategies, research priorities, policies, and decision making. Also called CISNET.
