Contrasting Fake News in Oncology: The First Declaration of Good Communication.

Purpose: Nowadays, websites, online journals, and social media give access to an extraordinary amount of medical information. Misleading news are often disseminated generating false expectations, exaggerated anxiety, and confusion; in oncology setting, disinformation is perhaps more deleterious than in other fields, with a considerable impact on single patients as well as on families and, more in general, on Public Health. We aimed to promote a better interaction between the health care and the world of communication.
