    Synthroid treats thyroid cancer by reducing the levels of another hormone called thyroid stimulating hormone (TSH). TSH is made in the pituitary gland, and it functions to make the thyroid gland produce more hormones. TSH stimulates the growth of thyroid cells, which can increase the cells that make up thyroid cancer. Lowering TSH levels will have the opposite effect, reducing the cells that make up thyroid cancer.
