The disruption of routine cancer screening during the COVID-19 pandemic is a public health priority given documented delays in the diagnosis and treatment of screening-eligible cancers, and future impacts on cancer mortality. Furthermore, COVID-19 has disproportionately affected historically underrepresented populations such as the Hispanic community, who already experience lower cancer screening rates compared to non-Hispanic whites. The purpose of this study was to examine inquiries about cancer screening among Spanish-speaking general public users before and during COVID-19, using data from the National Cancer Institute's Cancer Information Service (CIS). For this analysis, we examined cancer screening inquiries before (February 2019-March 2020) and during (March 2020-January 2021) COVID-19 among Spanish-speaking general public users. We analyzed CIS point of access (email, LiveHelp, social media, telephone), subjects of interaction, and referrals. Cancer sites with low cell sizes (e.g., lung) were combined into the category “other.” We conducted Chi-squared tests to compare counts for cancer screening inquiries before and during COVID-19 across these variables. There were 47.3% (n=691) cancer screening inquiries among English-speaking users before COVID-19 and 52.7% (n=770) during COVID-19. In comparison, among the 300 cancer screening inquiries from Spanish speakers, there were 57% (n=171) before COVID-19 compared to 43% (n=129) during COVID-19. There was a significant difference in patterns between these two groups (p&lt;.002). Cancer site inquiries among Spanish speakers included breast (n=66), general (n=108), and 17 other cancers combined (n=126). The proportion of breast and general cancer inquiries from Spanish speakers increased during COVID-19 compared to pre-COVID (p&lt;.001), whereas other cancer inquiries decreased. Additionally, Spanish-speaking telephone-based inquiries increased during COVID-19 whereas all other points of access decreased (p&lt;.001); subjects of interaction regarding general cancer questions increased, but those on finding healthcare services, screening tests, and other subjects decreased (p&lt;.01); and there was an increase in referrals to national/community organizations and to the CDC National Breast and Cervical Cancer Early Detection Program, although referrals to healthcare providers and other sources decreased during COVID-19 (p&lt;.001). We found that COVID-19 was associated with a significant decrease in cancer screening inquiries among Spanish speakers compared to English speakers using the CIS, with changes in point of access, referrals, subject of interaction, and cancer site for Spanish-speaking CIS users. It is critical to evaluate how these changes in information-seeking may affect screening behaviors post-COVID in Hispanic communities and may potentially widen existing disparities that have worsened during COVID-19. Despite overall inquiry reductions, there was an increase in some cancer screening referrals, hopefully resulting in increased screening behavior among Spanish-speaking CIS users.
