Considering the increasing trend of thyroid cancer and increased number of new cases we performed this study to determine the risk factors for thyroid cancer in Kurdistan Province.
80 patients and 80 controls were matched and entered into this case-control study from September 2009 to September 2016 in Kurdistan Province. Data were collected by reviewing the records of the patients, making phone calls and face-to-face interviews. Using SPSS v.20 software, data analysis was performed by chi-square test, T-test and logistic regression.
