Preliminary Estimates of SEER Incidence Through 2023
SEER*Explorer now includes preliminary estimates of age-adjusted rates and trends through 2023 based on delay-adjustment modeling of SEER Incidence data. These series preview patterns expected in the upcoming April 2026 data release. These estimates will be removed from the application in April when the official SEER estimates through 2023 are released. See Preliminary Cancer Incidence Rates and Trends, 2000-2023 for more details.
Preliminary estimates of SEER Incidence data are available for the following cancer sites:
