Abstract
With almost 430 000 new cases each year in France, the incidence of cancer continues to rise, doubling since the early 1990s. While much research focuses on so-called individual behaviours (smoking, alcohol consumption, diet, physical activity), much less attention is paid to occupational factors, which affect millions of employees. We will examine the social, economic and political logics behind the invisibilization of cancers linked to working conditions, both in scientific research and in prevention policies.
