Online Communities as Sources of Peer Support for People Living With Cancer: A Commentary

Online communities are virtual spaces dedicated to hosting conversations between individuals with a common interest. Information can be shared and obtained incrementally, as users can periodically post both questions and responses to other users’ questions. Although online communities have been used frequently by patients for a myriad of health issues, much remains to be learned about these resources. In this commentary, we explore the emerging role of online communities as forums for information exchange and sources of support for patients with cancer and caregivers. We discuss selected examples of online communities launched by research institutions, advocacy groups, philanthropic organizations, start-ups, and novel enterprises featuring collaborations between industry, health care professionals, and advocates. We explore the risks and benefits of online communities as perceived by oncology clinicians and provide practical recommendations for improving communication between clinicians and patients about the use of online resources.
