Abstract
INTRODUCTION: Breast and cervical cancer are the leading causes of cancer death among women worldwide. Given the growing concern, cervical cancer awareness month (CCAM) in January and Breast cancer awareness month (BCAM) in October occur annually as global health observances to raise public awareness. This infodemiology study aimed to assess trends in public online searches for breast cancer and cervical cancer following the annual BCAM and CCAM from 2008 to 2021. METHODS: Google Trends (GT) was used to investigate online searches for "breast cancer" and "cervical cancer" from January 1, 2008, to December 31, 2021. (168 months). A joinpoint regression analysis was used to identify statistically significant weekly percentage changes (WPCs) and monthly percentage changes (MPCs) trends over time. RESULTS: Breast cancer searches increased in October (BCAM) every year, while cervical cancer searches increased in January (CCAM) in 2013, 2019, and 2020. Joinpoint regression analysis revealed a significant negative trend in "breast cancer" searches from 2008 to 2021 (MPC: -0.2%, 95% CI: -0.3 to -0.1) and an upward trend in "cervical cancer" searches from May 2017 to December 2021 (MPC: 0.5%, 95% CI: 0.2 to 0.7). CONCLUSION: Online searches on "breast cancer" remain consistently high only during BCAM, and "cervical cancer" has increased by 0.5% MPC since May 2017. Our findings can inform online interventions like event-based opportunities (BCAM and CCAM) and Google Ads to raise public awareness of breast and cervical cancer.
