Quality and reliability of prostate cancer—Videos on TikTok and Bilibili: Cross-sectional content analysis study

Prostate cancer-related videos on Bilibili are generally of higher quality and reliability than those on TikTok. However, videos produced by urologists consistently demonstrated higher quality and reliability compared to those by patients across both platforms. Social media platforms should enhance the review and regulation of medical content to ensure its authenticity and accuracy, while content creators should aim to improve video quality to better meet the needs of a wider audience.
