Suppression vs QoL

Why is TSH suppression so often the sole or primary goal in thyroid cancer treatment with little regard for Quality of Life (QoL)? We are told, over and over, that the vast majority of thyroid cancer patients do just fine for the rest of their lives on synthetic thyroid hormone replacement (THR) therapy evaluated by… Continue reading Suppression vs QoL

As thyroid cancer patients, when things are not going well the first place we tend to look is to our thyroid hormone replacement (THR) meds. Just as our thyroid interacted with every aspect of our physical and mental health, metabolism and daily activity, we need to remain aware of how our overall health works withn… Continue reading What Blood Tests Should I Request?

Quick Thyroid Tour

When T4 and T3 go low, TSH goes high. The hypothalamus senses low circulating levels of thyroid hormone —Triiodothyronine (T3) and Thyroxine (T4) — and responds by releasing thyrotropin-releasing hormone (TRH). TRH - Thyrotropin-releasing hormone is a hormone produced in the hypothalamus that stimulates the release of thyroid-stimulating hormone (TSH) from the anterior pituitary gland.… Continue reading Quick Thyroid Tour

Tg Testing with Antibodies

Thyroglobulin Testing When You Have Positive Antibodies (TgAb} Thyroglobulin (Tg) is produced only by thyroid tissue and is the primary marker for follow up thyroid cancer detection after total thyroidectomy. It is not generally used after a partial or hemi-thyroidectomy as the remaining thyroid lobe will still produce normal levels of thyroglobulin. If you have thyroglobulin… Continue reading Tg Testing with Antibodies
