Behavioural and structural interventions in cancer prevention: towards the 2030 SDG horizon.

Traditionally, the prevention of cancer (and other chronic diseases) has been considered primarily linked to personal responsibility, for which interventions must be based on health education information enabling individuals to make knowledge-based decisions to improve their lifestyle. However, lifestyle is conditioned by environmental factors (including dimensions such as the context of economics, transport, urbanism, agriculture or education) that may render healthy behavioural choices either easier or, alternatively, impossible. This article reviews the conceptual underpinnings of the behavioural-structural dichotomy. We believe that it is advisable to opt for multilevel strategies that take into account all the determinants of health, using structural and behavioural approaches, rather than only the latter, as has been done until now.
