Social inequalities and cancer webinar

Thursday 21 January 2021
18:00 CET (Paris/Geneva); 12:00 noon EST
(Friday 22 January 06:00 NZDT)



People who have lower social or socioeconomic status or are from marginalized groups tend to have a higher incidence of and mortality from cancer. 

Several factors may lead individuals from low socioeconomic groups to adopt unhealthy behaviours, to be exposed to a wider range and a higher intensity of cancer risk factors, and to have reduced access to treatment and health-care services, compared with their fellow citizens.

This webinar will provide an overview of how the phenomenon of inequalities in cancer is shaped, and of how social and socioeconomic inequalities affect all countries worldwide and all citizens within each country (with examples from the USA and New Zealand). The experts will also touch on strategies to tackle inequality in cancer.
