The 2021 Cancer Incidence was High

The Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute (NCI) reports on cancer statistics, and the SEER 12 version shows a big jump in cancer in 2021:

While some of the increase could merely be late cancer detection in previously-missed cases from 2020, the Z-score on 2021 — using the mean and standard deviation from 2007-2019 — was a whopping 3.92.

Such a high Z-score invites follow-up research to determine if the COVID shots — given out en masse in 2021 — led to a steep rise in cancer incidence. Using a lagged percentage increase — i.e., the percentage change in the rate, compared to 3 years ago — 2021 was over 6% higher than 2018:

A typical increase in cancer incidence from 3 years prior is under 4%, but for 2021, that increase was over 6%. This ramped-up increase should trigger an investigation. A seven-year upward trend in cancer incidence from 2012-2018 shows that a typical yearly increase in cancer incidence is +4.2 per 100,000 — not +9.8 like for 2021 (from 2018).
