Infos

This is a unique book on thyroid neoplasms in that it covers many current topics in the area including tumor development, tumor markers and preclinical treatment for advanced cancer as well as practical approaches (radioiodine, ultrasound, thyroglobulin monitoring and PET scanning). This book will give the general reader and specialist a good foundation for what is currently going on in the area of thyroid neoplasms.

*A translational approach to thyriod neoplasms
*Contributions from national experts in research and clinical medicine
*Current and practical approaches to patients with thyroid neoplasms
