Trends in Cancer incidence rates, 1975-2019. US.

The Surveillance, Epidemiology, and End Results (SEER) Program provides information on cancer statistics in an effort to reduce the cancer burden among the U.S. population. SEER is supported by the Surveillance Research Program (SRP) in the National Cancer Institute's Division of Cancer Control and Population Sciences. As per its website claim, SRP provides national leadership in the science of cancer surveillance as well as analytical tools and methodological expertise in collecting, analyzing, interpreting, and disseminating reliable population-based statistics. And SEER is an authoritative source for cancer statistics in the United States. We would agree, it is perhaps one of the most robust cancer registries worldwide.

A cursory observation of information on trends and incidence rates (1975-2019), would suggest that the incidence rates per 100,000 population have not changed drastically. In the year 2019, it stood at 451.2 (2019) compared with the historical figure of 444.6 (1986). Did I miss something? Has the mechanism/analysis of input data into the disease registries improved? Has the pathophysiological and risk character of cancer undergone changes? Expectedly there has been an improvement overall in detection and treatment outcomes.
