AB OBJECTIVE To analyze the incidence rate and trend of thyroid cancer in Tianjin over a recent 20-year period.METHODS A method of descriptive epidemiology was used to study the occurrence of thyroid cancer.RESULTS During 1981 ∼2001, the average incidence rate of thyroid cancer was 1.770 per 100,000 with a male to female incidence ratio of 1:2.74, the occurrence being higher in females than in males. Thyroid cancer incidence increased gradually with time over the 20 years in both males and females, especially the incidence peaked in females of 35∼50CONCLUSION The rapid increase in the incidence rate of thyroid canInstitute and cer, especially in females, suggests that further research on the risk factors and preventive efforts related to high -risk women should be con ducted.
