My dad 70 years had high TSH 54 , low T4 0.4 and enlarged thyroid for 4 years. He has taken eltroxin since then . Can this turn into thyroid cancer?

My dad 70 years had high TSH 54 , low T4 0.4 and enlarged thyroid for 4 years. He has taken eltroxin since then . Can this turn into thyroid cancer?

Unlikely: Goiters due to hypothyroid conditions are benign and should settle down once replacement thyroxine has been used to control the problem. Cancer is rarely a concern in this situation, yet if the thyroid enlargement is substantial then you should consult an ENT doctor who deals with thyroid enlargements(or seek an endocrinologist 's opinion). Good luck. ...Read more

We have case , femal patien , age 60 years, the TSH less than 0.05 while T4 in normal range , and she has not any symptom of thyroidism , is it ok ?

Subclinical hyperthy: A low TSH with a normal T4 and no symptoms is usually subclinical hyperthyroidism. She may have a multinodular goiter that is autonomously functioning, or very early graves disease. A T3 (liothyronine) level and free T4 level should be checked. There is a higher risk of developing atrial fibrillation despite the normal T4 level, but many endocrinologists would just follow her levels for progression. ...Read more

Hypothyroidism.: In hypothyroidism, TSH is high because it is a reaction to thyroid hormone/free thyroid hormone being low. The hypothyroid can be due to many causes, but this is the main effect. Your TSH is slightly high at 5.4 (normal 0.4 - 5.0 mu/l) and your T4 is apparently low (normal 64 - 154 nmol/l), so your dr. Treated you with thyroid replacement. You should visit your dr. Routinely for check-up. ...Read more

Would TSH 5.4 and T4 7.6 be considered mild or severe? What test would my doctor have to do to know what caused my thyroid to be low?

Mild; repeat test: In most assays, the T4 is normal, and TSH slightly elevated. This could be nothing; sometimes a repeat test will come back normal. The question to ask: is your thyroid gland starting to fail? If so, it is early. Family history? Do you have symptoms? Positive anti-tpo antibodies? If you have symptoms and if there is evidence that your thyroid is failing, you should start on levothyroxine. ...Read more
