Papillary thyroid cancer: sporadic or inherited?

Abstract

Background: Papillary thyroid cancer (PTC) is one of the most common thyroid malignancies, with an increase in incidence rates over the past few decades. Although the exact cause of thyroid cancer in most patients is still unclear, the possibility of genetic predisposition to PTC cannot be overlooked. Here, we report a case study of PTC, in which the family was extensively affected, with each family member diagnosed with either benign or malignant thyroid neoplasms, or functional thyroid disorder.
