Introduction to focused issue on mHealth and social media interventions for cancer

Rapid advances in mHealth and social media technologies are contributing to a burgeoning number of novel clinical and public health interventions for preventing, controlling, diagnosing, and treating cancer (1,2). Exciting innovations in mHealth and social media applications are occurring across the cancer spectrum, from primary prevention to screening, early diagnosis, treatment, survivorship, and end-of-life care. Additional innovations in technologies are enhancing research data collection and patient recruitment and treatment adherence in oncology trials (2,3). The articles included in this focused issue of the journal highlight many of these important developments and future directions.
