Sociodemographic characteristics associated with thyroid cancer risk in Canada

Using the 1991 and 2001 Canadian Census Health and Environment Cohorts (CanCHECs), this study examines thyroid cancer incidence over nine years of follow up; presents estimates of the sex-specific relative risk of thyroid cancer according to age, immigrant status, ethnicity, educational attainment and family income; and examines whether these relative risks changed over time.
