Educating Cancer on TikTok: Expanding Online Self-Disclosure of Cancer Patients

The article uses the concept of online self-disclosure and examines whether TikTok videos reveal information similar to what is reported in existing research on social media within this field. In addition, the study aims to identify the creators’ motivations and the meanings they attribute to disclosing cancer and asks whether this disclosure challenges or supports the concept of a positive culture defined within the online self-disclosure framework. While similar research typically focuses on posts and is thus limited, this study combines conventional content analysis of 862 videos with in-depth interviews, offering a more nuanced understanding of the users’ lived experience. The findings highlight that TikTok is a platform for negative (e.g., fears, anxiety) and positive self-disclosure (e.g., joyful life events, self-acceptance). What is crucial, though, is that users feel exceedingly competent in educating others. The research debunks positive culture as an overly general category and undermines the traditional understanding of online self-disclosure. It reveals that seeking support is less important for patients than informing and warning others. By focusing on the educational meanings attributed to self-disclosure, this study enriches the body of research on cancer-related content shared on TikTok, including studies on low-quality cancer-related information.
