Incidence pattern of thyroid cancer in norway: Influence of birth cohort and time period
Abstract The incidence of thyroid cancer in Norway increased about 2‐fold for both sexes during the period 1955 to 1989 (4691 cases). In the last 5‐year period, however, a decline was observed, especially among females. The ratio between age‐ adjusted incidence rates in Northern Norway compared with...
