Summary
Brief summary (as posted)
The study is a multi-center prospective cohort study of active surveillance in papillary thyroid cancer with low risk. The purpose of the study is to observe natural course of low risk papillary thyroid cancer in Korean population, and comparison of prognosis between active surveillance group and conventional surgery group. Patient will be well informed about their choice of active surveillance or surgery.
