[Thyroid cancer in Poland in 1980-2000].

The objective of this paper was to assess the occurrence of thyroid cancer in Poland between 1980 and 2000 concerning incidence, hospitalisation and mortality. The frequency of thyroid cancer is relatively low - 0.5% in men and above 2% in women among all malignant. Mortality of thyroid cancer is on the low, stable level - 0.45 death per 100 000 in men and 1.05 in women. Hospital morbidity caused by thyroid cancer is almost three-fold higher then incidence. In the framework of 1980-2000 the substantial increase of incidence was observed especially since 1991 in women and in 1992-1993 and 1999-2000 in men. It could be associated with the pause in iodine prophylactic in 1980. Factors such radiation from medical treatment, ionising radiation as well as environmental, nutrition and genetic conditions may play role as a risk factors. In the last years slightly increase of incidence of thyroid cancer was observed in the population of 0-15. It could be possible caused by radiation after accident of the Chernobyl.
