The effect of menopausal hormone therapy on thyroid cancer survivors from the National Health Insurance Database in South Korea cohort

CONCLUSION: The risk of death in postmenopausal TC survivors who used MHT for > 5 years did not differ from that of their counterparts who did not use MHT. However, postmenopausal TC survivors who used MHT for < 5 years, particularly those who used MHT for < 6 months, had a higher risk of death than their counterparts who did not use MHT.
