I'm doing a project for school and i am trying to find out treatments for thyroid cancer.is there any standard procedures?

Yes: Surgery is the most important. Depending on the type, radioactive iodine is given. The most common type is papillary. There are other types, medullary, follicular, and anaplastic. Sometimes chemotherapy is given for anaplastic, however, this type commonly occurs in the elderly. Hope this helps.

Guidelines: You might want to read the guidelines from respectable organizations. Here is one from the american association of clinical endocrinologists. It can get very complicated but in general: surgery +/- radioactive iodine, then surveillance and repeat surgery or repeat radioactive iodine as needed, https://www.Aace.Com/files/thyroid-carcinoma.Pdf.
