My TSH level is 42.62 do I have thyroid cancer?

My TSH level is 42.62 do I have thyroid cancer?

Not really.: This is very high level. The normal range is around 0.4 - 5.0 mu/l, so this is very high. This, first and foremost, suggests low thyroid hormone production, and is a sign of hypothyroidism. The cause of this might be linked to thyroid cancer, as cancerous nodules are usually "cold" or produce no thyroid hormone, but, on its own, does not point to cancer. ...Read more

My TSH level was 0.215 on 12/17/13 and was 0.584 on 5/21/13. I've been taking my meds the same. Could this mean my thyroid cancer has returned?

No, don't worry!: Tsh is not made by thryoid cancer! it's made by your body to stimulate your thyroid to produce hormones. Tsh can stimulate thyroid cancer cells, too, so the medicine you take is to keep your TSH level as low as possible. The fact that your TSH has risen might be a sign that you need to take a higher dose of your medication. This is something you should ask your doctor about! ...Read more

I'm just wondering, if you have thyroid cancer will your TSH level in your blood test be off?

I'm just wondering, if you have thyroid cancer will your TSH level in your blood test be off?

Not necessarily: Tsh stands for thyroid stimulating hormone. It does exactly that-- tells your thyroid to make thyroid hormone. If your thyroid isn't making enough hormone, your TSH will increase. And if your thyroid is making too much hormone, your TSH will go down. But cancer is usually not the cause for a high or low tsh. And you can have a completely normal TSH and still have thyroid cancer. Hope that helps! ...Read more

Could an elevation in one's TSH level be indicative of hyper/hypo thyroidism?

Could an elevation in one's TSH level be indicative of hyper/hypo thyroidism?

Hypothyroidism: When the thyroid makes too little hormone (t4 and t3), the pituitary makes more TSH to try to compensate. So an elevated TSH is indicative of a thyroid that has failed or is failing, and you may need to take levothyroxine. See your doctor. ...Read more
