DevCan - Probability of Developing or Dying of Cancer. Statistical models are used to compute the probability of being diagnosed or dying of cancer from birth or conditional on a certain age. DevCan takes cross-sectional counts of incident cases from the standard areas of the Surveillance, Epidemiology, and End Results (SEER) ProgramExternal Website Policy conducted by the National Cancer Institute, and mortality counts for the same areas from data collected by the National Center for Health StatisticsExternal Website Policy, and uses them to calculate incidence and mortality rates using population estimates from census data for these areas. These rates are converted to the probabilities of developing or dying from cancer for a hypothetical population. Please note that when the program refers to cancer or incidence, it is referring only to the cancer site that you requested.
