Hi, I hope this puts your mind at ease :-)
TSH = thyroid stimulating hormone
T3 & T4 = thyroid hormones
The thyroid gland can become cancerous like any other tissue in the body but these tests are NOT specific for cancer.
The test is to check the levels of these hormones to see if they are to high or low.
Usually given to rule out thyroid overactivity which can cause weight loss, anxiety and tremor.
Hi,
I'm not a doc, but usually the labs in thy cancer patients are normal or close to normal. So really it usually just shows the hormonal levels.
Just my 2 cents.
