The Web-Based Randomized Controlled Intervention as the Enhancer of Cancer Prevention.

Background and Objectives: Cancer is an unresolved public health issue in society. With the advent of the internet and the development in the technological sector, access to basic health-related information has become more frequent among patients and healthy individuals. The aim of this study is to evaluate the impact of educational intervention on the participant's willingness to undergo selected medical procedures in case of suspected cancer. Materials and Methods: From 14 May 2015 to 13 November 2016, a total of 1118 who visited the Polish scientific website were enrolled in the 'Polish Online Randomized Intervention aimed at Neoplasm Avoidance' (PORINA) and randomized into two groups (educational and control). The original Cancer Knowledge Index (CKI) was used for the evaluation of participants' cancer-related knowledge. They were asked to declare whether they would consent to undergo selected medical procedures necessary for cancer diagnosis or treatment. Results: Most participants declared their readiness to undergo abdominal ultrasonography, computed tomography, and a nevi excision. The most noticeable changes were found for potential consent to undergo breast fine needle aspiration, mammography and gastroscopy. Conclusions: The level of oncological knowledge has an impact on individual decision to consent to particular medical procedures. Conducted educational intervention has significantly increased the readiness to undergo selected medical procedures.
