Introduction to special section on digital technology and cancer survivorship.

Technological advances in health care have led to increasing numbers of curable and treatable cancers extending the lives of many people around the world. Alongside these advances, the development and accessibility of modern technology including the internet, social media, smart phones and apps are revolutionising how we communicate and receive information and store and monitor data. This in turn has led to novel methods of supporting people living with and beyond cancer. In this special section of the Journal of Cancer Survivorship, we are pleased to present a collection of seven papers showcasing a variety of technologies and research methodologies. Each demonstrates the utilisation of different digital approaches for either improving our understanding of the lives of people surviving cancer or assisting the management of the consequences of the disease. Collectively, the papers raise a number of important questions for future exploration as we adapt to an ever more digitally focussed society.
