thyrogen bloodwork...cancer or "good" thyroid tissue

When taking thyrogen injection before body scan and they take your bloodwork, if it comes back high does that mean that the mass (even though small) they saw in a sonogram is 100% cancerous or could it still be "good" thyroid tissue?

What thyrogen number is considered OK and what is considered high?

    what is your tg level on thyrogen (stimulated tg level)?
    When some tissue is visualized on a sonogram - even if tg is elevated or not, techinically there is no way of knowing if it is regular thyroid tissue or cancerous tissue without a biopsy.

    I remember your tg was 14 and then dropped to 1 or something in the next draw... was one of those tests with thyrogen (stimulated level)?

    Boy, you have a good memory!
    I go for my thyrogen and body scan next week.
    I had a sonogram over a month ago and the sono dr said there was a small mass in my neck. To him it looked like thyroid tissue.
    My endo dr said the next step would be either thyrogen/body scan or biopsy. (He left which one I had up to me.) I asked if one was better than the other for showing if it was cancer or not and he said they were both about the same. He said he would start w/the thyrogen/body scan and could always do the biopsy later. (I don't know if it is because the biopsy is more invasive.)

    So, I opted for the shot/scan. But now I am having second thoughts and wondered if I should have gone the biopsy route. To me, that would be more definitive. Especially since I had a body scan in March and it showed up negative...BUT, the dr I had at that time didn't do the thyrogen bloodwork so even though the scan was negative I never got a precise answer. (I didn't know that until I changed drs.)

    If thyrogen comes back low, then what would the small mass in my neck mean? "Good" thyroid tissue?
    I just hate the waiting!
