For the study, international researchers reviewed 245 academic articles from 46 countries to analyze the scale of COVID-19’s disruption on cancer care.

Here are four notes from their analysis:

  1. In addition to the 39% decline in cancer screening, diagnostic procedures declined by 24% and cancer diagnoses declined by 23% compared to prepandemic levels.
  2. Cancer treatment declined by 28% overall, with a 15% decline in radiotherapy treatment and a 35% decline in systemic treatment, compared to prepandemic levels.
  3. Countries with high and very high human-development indexes experienced fewer cancer care reductions compared to countries with medium human-development indexes, while cancer care data from countries with low human-development indexes were “missing,” study authors wrote.
  4. A different, recent study analyzed how the COVID-19 pandemic influenced cancer incidence rates. Between January 2020 and December 2021, the cancer incidence rate in the U.S. was 6% lower than expected, equating to 149,577 potentially missed diagnoses.
