Associations have been observed between socio-economic level and health related variables including mortality and to a lesser extent morbidity. Various studies have related lower socio-economic level with higher cancer incidence and mortality risk. However, in most cases these associations have not been considered causal because the socio-economic factors are also related with exposures to environmental risks. There is very little research on the association between cancer incidence and socio-economic conditions.
