My TSH level is 12.87, I got put on sythroid, how do I know it's not thyroid cancer?
My dr. did not run any other blood test (he's my GP). He says I do not need to go to an endocrinologist. How do I know the level is n ot from a thyroid cancer? I'm 38, female, have had 3 children. I'm a bit paranoid because my brother in law (no blood relation) is my age and has thyroid cancer.

- If you feel strongly about this, ask your Dr. to do a thyroid ultra sound.
I have had several done, it is painless, and will show exactly what is going on in there.
- You're female, of the right age, and most likely it's a dying thyroid. If the next blood test comes out fine, that's your indication it's not cancer -- and this test is way cheaper to run.
My own GP does a similar thing - if he thinks but is not certain it is something, he gives me meds for it and if it works, he has a diagnosis. It's way cheaper in the long run and keeps insurance prices down -- a good thing from my perspective.
- It makes sense to get a second opinion. I would. It'll make you feel better and you'll have two view points. If there is a difference, then you get a THIRD... OR go with a biopsy.... but just go for a second opinion, at this point....
- The thyroid functions as a negative feedback loop: if the thyroid hormones (T3, T4) get too high they will suppress the production of TSH from the Pituitary. Too low of levels will allow TSH to be released. A level of over five is too high, so you will probably benefit from synthroid. A thyroid malignancy would be unlikely to produce too little of thyroid hormones and , therefore, unlikely to cause an elevated TSH. My impression is that your doc has done ok so far and that you'll feel better after being on Synthroid for a while (it takes a few days to work.)
- If you are on synthroid, it is not likely that you have cancer. Did they do any further tests other than a blood test? If not, I would get back to the doctor and ask for further results. I know many people who are on med for their thyroid, my sister, son, and myself. It seems hereditary. Relax...you should be fine!
