High TSH levels after thyroid cancer.Been on Synthroid (thyroxine) for 3 yrs and has been fine now all the sudden levels out of wack and lump in neck ?

See endocrinologist: Go back to your endocrinologistt or thyroid surgeon. Elevated TSH suggests that you need thyroid replacement meds increased. New lumps may or may not be significant. A good physical examination and ultrasound should be able to help here and a fine needle aspiration may be warranted. Thyroid cancer frequently recurs in lymph nodes and is very curable. ...Read more

Cancer (Definition)

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

Does high TSH indicate cancer?

Does high TSH indicate cancer?

No!: Tsh stands for "thyroid stimulating hormone". It does exactly what it says; stimulates your thyroid to produce hormones! if your thyroid is not producing enough thyroid hormone, your TSH will go up. So a high TSH simply means you have an underactive thyroid gland (hypothyroidism). There are many conditions that cause this, and they are easily treatable. See your health provider! ...Read more

Can a high TSH that is not monitored and controlled stimulate latent cancer to grow?

Can a high TSH that is not monitored and controlled stimulate latent cancer to grow?

Two main concern: Two main concerns are if someone has prior h/o thyroid cancer which was surgically removed; in that case if TSH level goes high it theoretically can place one at higher risk for recurrence as goal of therapy after that type of surgery is to keep TSH low-normal; 2nd is if one has pituitary tumor (that is where TSH is coming from) and usually causes high thyroid levels; that should be managed; ...Read more

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

23 yrs old f; thyroid peroxidase 13 (norm); thyroglobulin, antibody 3.0 (high); TSH 10.850 (high); nomal T3 (liothyronine) & t4. Hashimotos? Possible thyroid cancer

Possible to 1st : Thyroglobulin is a test that is helpful after someone has surgery for the most common thyroid cancer. Thyroid function tests can test how well your thyroid is working.

I have a high TSH but normal T4 levels, what does this mean?

I have a high TSH but normal T4 levels, what does this mean?

Hypothyroidism: The TSH test is10 times more sensitive for the diagnosis of hypothyroidism that the t4. The TSH is reported on a log scale so that small changes in the TSH value are caused by relatively big changes in the blood level. This is a reflection of the pituitary being extremely sensitive to change in the T3 (liothyronine) level if you have symptoms it would be wise to seek treatment. ...Read more

I have high TSH 5.28 and 2 weeks down to 3.4 without meds? Im also hypertensive and I have brugada syndrome. Why my TSH levels drop without meds?

Various possibilitie: There's always potential lab error. Morning determinations are generally most accurate. Tsh is secreted episodically and can vary from one time to the next, also, if you have had a recent bout of thyroiditis, your labs can vary over time. Did they draw any other thyroid tests like free t4? Reheck you level in the future. ...Read more

What is considered a high TSH level?

What is considered a high TSH level?

Above 4.5: In most labs, a value above 4.5 is high. However, symptoms related to low thyroid correlate much better with free T4 levels, rather than tsh. There are many people with elevated tsh, normal free t4, who feel perfectly normal (subclinical hypothyroidism). Persistently high TSH levels is indicative of a failing thyroid. ...Read more

What is a dangerously high TSH level?

What is a dangerously high TSH level?

Hypothyroidism: The actual thyroid hormone is T4 and t3 (liothyronine). When they are low, TSH elevates, but how high is somewhat variable, and "high tsh" per se is not dangerous. A low t4/t3 (liothyronine) can be dangerous; TSH is a good marker of thyroid function, but often it is necessary to measure ft4 or t3 (liothyronine). A mild elevation of TSH (eg. 4-10) is often without any symptoms and a normal ft4. ...Read more

My last blood results showed a high TSH levels but t3andt4 in normal range. Should i see someone regarding hypotyhroidism?

Yes: An elevated TSH indicates that your pituitary gland feels that your thyroid level is somewhat low. The fact that the T4 and T3 (liothyronine) are normal means that the problem is still mild. If you have symptoms of an underactive thyroid, treatment with thyroid hormone is indicated. If you have no symptoms, and the TSH is only mildly high, one can repeat the level in a few months and see if it has changed. ...Read more

33 yr M 6'2 185 pounds. High TSH levels but normal free T4, whst exactly does this mean?

Subclinical hypothyr: Hi. That is commonly seen, now that we screen so well for disorders of thyroid function. It's called subclinical hypothyroidism, meaning that with extra push from the pituitary (TSH), the remaining thyroid tissue is able to make thyroid hormone in the normal range. You should start taking thyroid hormone now, and not wait till your metabolic tank is empty. Good luck! ...Read more
