Follicular thyroid carcinoma

Anaplastic thyroid carcinoma

Papillary thyroid carcinoma

Question Category:

Radiology

Correct Answer:

Papillary thyroid carcinoma

Description:

The incidence of thyroid carcinomas, predominantly papillary thyroid carcinomas, increases in humans after radiation exposure. There is strong dependence on age at exposure—susceptibility to radiation-induced thyroid cancer is higher in children than adults. There is little evidence for a dose response for individuals exposed during adulthood. Females are 2 to 3 times more susceptible than males to radiogenic and spontaneous thyroid cancers.Reference: White and Pharoah, Oral radiology, ed 8th, pg-92
