Cancer Registry
Data on cancer incidence, type, stage at diagnosis, treatment, and survival is collected by the Cancer Registry and reported to the Delaware State Central Registry. Registry data is also submitted to the National Cancer Data Base, which uses this information to monitor cancer trends, plan cancer prevention programs, help set priorities, and advance medical research efforts.
