New cancer diagnoses did not rebound as expected following pandemic

 A recent study appearing in the Journal of the National Cancer Institute indicates "little evidence of a rebound in incidence" with regards to a decline in cancer diagnosis during 2020, the first year of the COVID-19 pandemic.  After scrutinizing 5 major cancer types (breast, prostate, lung, pancreatic, thyroid),  "cancer incidence rates overall [in 2021] for most specific cancers approached pre-pandemic levels", with the exception of breast cancer and pancreatic cancer, which showed an increase, while thyroid cancer diagnoses fell below pre-pandemic levels.  As such, 2021 has been considered "a transition year that was still affected by new variants and new waves of COVID-19 cases."
