Thyroid cancer.

In recent decades, the diagnosis of thyroid cancer, especially the papillary type, has increased significantly due to the use of imaging techniques such as ultrasound. For this reason, it is essential to rationalize diagnosis and treatment, since the behavior of thyroid cancer varies from slow-progressing tumors to highly aggressive ones. The application of risk assessment systems for ultrasound images and the optimization of cytology incorporating molecular studies allows cases to be stratified in order to select therapy on an individual basis. Currently, attempts are being made to avoid overtreatment in low-risk tumors, with active surveillance or minimally invasive techniques. The administration of radioiodine is indicated according to risk, with lower doses, and in advanced cases, oncospecific systemic treatments are being incorporated. The management of thyroid cancer requires a multidisciplinary team and population studies and quality clinical trials are necessary to update treatment guidelines.
