Apart from the essential trace element iodine, which is the central constituent of thyroid hormones, a second essential trace element, selenium, is required for appropriate thyroid hormone synthesis, activation and metabolism. The human thyroid gland has the highest selenium content per gram of tissue among all organs.
What is the main cause of thyroid cancer?

What is the main element of thyroxine hormone?
The thyroid hormones, thyroxine (T4) and triiodothyronine (T3), are tyrosine-based hormones produced by the thyroid gland. An important component in the synthesis is iodine.
What is thyroid cancer called?
Papillary carcinoma is the most common type of thyroid cancer, accounting for approximately 80 percent of cases. Papillary carcinomas are slow-growing, differentiated cancers that develop from follicular cells and can develop in one or both lobes of the thyroid gland.
What happens to your body when you have thyroid cancer?

Does Thyroid Cancer kill you?

What mineral is important for thyroid function?
Abstract. Micronutrients, mostly iodine and selenium, are required for thyroid hormone synthesis and function. Iodine is an essential component of thyroid hormones and its deficiency is considered as the most common cause of preventable brain damage in the world.
Which multivitamin is best for thyroid patients?

What are thyroid hormones made of?
Thyroid hormones are two hormones produced and released by the thyroid gland, namely triiodothyronine (T3) and thyroxine (T4). They are tyrosine-based hormones that are primarily responsible for regulation of metabolism. T3 and T4 are partially composed of iodine.
What hormone causes the release of thyroxine?
The hypothalamus secretes thyrotropin-releasing hormone which, in turn, stimulates the pituitary gland to produce thyroid stimulating hormone. This hormone stimulates the production of the thyroid hormones, thyroxine and triiodothyronine, by the thyroid gland.
