The objective of our study was to compare recent secular trends in the morbidity and mortality rates of thyroid cancer among the children and adult populations of West Pomeranian and Pomeranian Voivodeships in 2000 and 2016. The number of thyroid cancer cases and incidence rates were retrieved from the Regional Cancer Registries for the period 2000-2016. The number of deaths and mortality rates was obtained from the cancer mortality database (2000 and 2016 by regions). The increase in the incidence rates among the female population in the Pomeranian Voivodeship was observed (from 11.31 in 2000 to 32.04 per 100,000 persons in 2016). Among the child population, the incidence has increased slightly among girls. The adult mortality rate remained unchanged during the study period and was not recorded among other populations. The highest incidence in West Pomeranian Voivodeship is observed among women in 2016 and stands at 22.46 per 100,000 population. Mortality increased slightly during the study period among the female population. The relative risk of thyroid cancer mortality was increased among the adult population of West Pomeranian Voivodeship. Therefore, both thyroid cancer morbidity and mortality are occurring mainly at the expense of the female population. These trends, combined with overall high mortality and high 15-year increase of morbidity, raise concerns on the extent to which the situation may be taking place.
