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

Past thyroid cancer, now years later I have abnormal blood calcium, what to do?

Past thyroid cancer, now years later I have abnormal blood calcium, what to do?

Parathyroids: Presumably, your thyroid cancer treatment involved surgery and radioactive iodine. Usually, this preserves the parathyoid glands, but sometimes they can get damaged. Parathyroids make PTH which maintains blood Ca. If PTH is low, your blood Ca will fall, and cause a number of symptoms. For starters, get an ionized Ca and PTH. See your Endocrinologist. ...Read more

I had thyroid cancer in the past. Now years later I have abnormal blood calcium. Could these be related?

I had thyroid cancer in the past. Now years later I have abnormal blood calcium. Could these be related?

Some relationship: Calcium metabolism is controlled vial the parathyroid glands. There are 4 such glands, 2 on top of the thyroid and 2 at the lower pole. When a total thyroidectomy is performed for Ca some of the glands may be injured and the Ca++ levels drop. If the remaining glands grow post op they produce excess hormone then the level of serum Ca++ becomes elevated. ...Read more

Could you tell me if someone has thyroid cancer wouldn't the CBC blood test show that something was abnormal?

I have a couple of 6mm lymp nodes and my mchc came back low on my blood test. Does one have to do with the other? I also had thyroid cancer last year.

I have a couple of 6mm lymp nodes and my mchc came back low on my blood test. Does one have to do with the other? I also had thyroid cancer last year.

Cannot say: cannot say in your particular case, but generally, 6mm lymph nodes are not necessarily significant. MCHC low implies low iron, but can be wtih a chronic disease (active or recovering from cancer, among many many others). BUt could also theoretically be the beginning of a return of the cancer. ...Read more
