The TSH (thyroid stimulating hormone) is an essential hormone to follow up for a thyroid dysfunction suspicion. This dosage will also be essential to check an abnormal thyroid function, and also after total thyroidectomy in a thyroid cancer. It is a very simple and routine sample which will help correct certain biological thyroid disorders, and it will be useful for the replacement therapy after a total thyroidectomy for thyroid cancer.
What is the TSH ?
- T3: tri-iodothyronine or T3
- T4: tetra-iodothyronine or thyroxine, a reserve hormone produced in greater quantities than T3. So, if thyroid hormones are needed, T4 can be converted to T3 and become active.

TSH : what’s the use after a cancer ?
Every treatment for cancer will start on the first intention with a thyroid surgery. Surgery is in most of the cases full, which leads to a definitive hypothyroidism necessitating a lifetime hormone replacement therapy.
After a thyroidectomy, a hormonal substitute treatment will be needed. The TSH test will show us if the substitutive treatment is adapted or if is not. The TSH level will be checked 6 weeks to 2 months after a replacement therapy to adapt the treatment the best as possible.
In that case, the level of T3 or T4 hormones won’t have any interest. T3 should stay normal. Once we have the perfect hormone therapy, an annual or biannual TSH blood test should be enough.
A diet rich in iodine to overcome hypothyroidism?
A rich iodine diet may be beneficial for hypothyroidism in order to overcome certain hypothyroidism symptoms such as weight gain or fatigue. This diet must be rich in iodine and nutrients to produce more thyroid hormones: selenium, vitamin B12 and vitamin D. It will be interesting to eat fish, seafood, eggs, Brazil nuts, dairy products…
Thyroid hormone supplementation after total thyroidectomy for thyroid cancer is essential, TSH level is important to adjust the therapy replacement and for the patient’s comfort.
