Date Time Study shows sharp decline in cancer screenings and diagnoses during first COVID-19 surge Focusing on the largest health care system in the Northeast, the study is among the first to document the pandemic’s impact on cancer screening and diagnosis. Screening and diagnoses rebounded in the months following the first surge of the pandemic. The authors urge those who delayed screenings during the height of the pandemic to contact their health care provider to discuss the potential need to reschedule one. In one of the first studies to examine the impact of the COVID-19 pandemic on cancer diagnoses, researchers at Dana-Farber/Brigham and Women’s Cancer Center document a substantial decline in cancer and precancer diagnoses at the Northeast’s largest health care system during the first peak of the pandemic because of a drop in the number of cancer screening tests performed.
