Mapping the online social network of cancer bloggers.

While social media has the ability to quickly disseminate information and reach large audiences, cancer blogs as a communication platform have not yet been well studied. A social network analysis was conducted on 89 active cancer blogs. Results demonstrated the overall cancer-blog-network was widely distributed and decentralized, with blogs clustered by cancer type, and that breast cancer blogs were the most significant and highly linked blogs. Efforts to disseminate cancer-related information may focus on identifying key breast cancer bloggers or linking key bloggers of various cancers to create a more interconnected network and expand its reach within this online community.
