Better access to diagnostic tests raises incidence of thyroid cancer in more affluent areas

The incidence of thyroid cancer in São Paulo State, part of Brazil’s relatively developed Southeast region, varies considerably according to socioeconomic status (education, poverty, wealth, income, segregation, mobility, and access to resources and services) and access to screening, but is highest in higher-income areas and the state capital. Mortality rates are similar across regions and income groups, however.
