Left thyroid papillary carcinoma. Some follicular cells show hurthle cell/oncocytic changes. Is the treatment generally thyroidectomy & rad. Iodine?

Size matters. Depending on size and charevteristics most would recommend a total thyroid and possible radioactive iodine. Speak to your surgeon and endocrinologist.
Generally Yes. Here is good patient resource online: http://www.Cancer.Net/cancer-types/thyroid-cancer.
It depends. It depends on the size of the tumor. Most surgeons agree that total thyroidectomy is preferable, although there are dissenters. This allows treatment with radioactive iodine and gives us the ability to follow a marker in the blood, thyroglobulin. For very small tumors, observation alone is an option.
