Aim: Thyroid cancers are the most commonly encountered endocrine system malignancies. The incidencecontinues to rise worldwide. Our aim in this study is to investigate the frequency and histopathologicalsubtypes of thyroid cancer in our clinic. Methods: The present study was conducted with 3614 patients who were followed up in our endocrinologyand general surgery clinic and operated with the diagnosis of multinodular and/or nodular goiter between 2015and 2021. The histopathological types and information of patients diagnosed with thyroid cancer were obtainedretrospectively from the pathology reports. Among the patients included in the study, a total of 570 peoplewho were reported to have thyroid cancer due to histopathology were included in the study. Results: The data of a total of 3614 biopsy reports were examined for the study. Among these patients, 570(421 females, 149 males) were operated and whose pathology reports were accessed were included in thestudy. The mean age of the patients was 49.12±10.4 years. As a result of the operations, malign postoperativetissue histopathology was 98.9% (n=564), and uncertain malignancy potential was reported to be 1.0% (n=6).In our study, the histopathological distribution of thyroid cancers was as follows; thyroid papillary cancer89.4% (n=510), follicular cancer 7.3% (n=42), medullary cancer 2.1% (n=12), and malignancy potentialuncertain 1.0% (n=6). Conclusion: The results of our study suggest that thyroid cancers are more common in women in our country,in parallel with the similar rates reported in the literature, with the increase worldwide.
