There is still a consensus about systematic surgery for solitary isolate nodules in case of suspicious nodules larger than 4 cm. In view of the increasingly frequent possibility of recurrence, this policy may now be made more flexible by the results of cytological puncture, leading to the removal of malignant or suspicious nodules and of those with follicular cytology. Better knowledge of the populations at cancer risks (subjects younger than 30 or older than 60, male subjects, history of cervical radiation therapy), allows setting up follow-up for women from 30 to 50 years of age.
