Exposure to radiotherapy for first primary cancer as a risk factor for second primary thyroid cancer: A case-control study.

Background: Second primary neoplasms are associated with high mortality and morbidity rates in cancer survivors successfully treated for the first malignancy. Studies suggested an association between the type of first neoplasm and risk of subsequent thyroid cancer, with part of this risk attributable to exposure to radiotherapy during treatment of the first primary tumor. This study aimed to determine whether radiotherapy is a risk factor for thyroid cancer in patients previously treated for another neoplasm.
