Latest report on Cancer in Connecticut.   



The Connecticut Tumor Registry (CTR) is a population-based resource for examining cancer patterns in Connecticut. The registry's computerized databases include all reported cancers diagnosed in Connecticut residents from 1935 to the present, as well as follow-up, treatment and survival data on reported cases. All licensed medical providers in Connecticut, as well as all hospitals and private pathology laboratories, are required by law to report cancer cases to the registry.


The identities of all patients reported are protected by state confidentiality laws.


The registry has been part of the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) program since its inception in 1973. SEER data are reported by 19 geographical areas comprising approximately 34% of the US population, selected for their ability to manage a high quality cancer surveillance system and to provide a representative subset of the nation’s population.
