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

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

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
