4cm thyroid nodule + high TSH level

[cferreira172]

I had hypothyroidism when I was a kid, but with good blood tests for years, I got myself off of the synthroid. (probably 8-10 years ago) For the past two years, I have had many thyroid syptoms (symptoms) ranging from depression to massive weight gain and alot of fluid retention in my legs. I went back to my endo and my TSH level was 13.3 (it said normal should be 0.34-5.60). They called and told me my hypothyroidism came back and they put me on 50MCG (0.05MG) levothyroxine.
I went for an ultrasound and they called me today to tell me that they found a large 4cm nodule. They are sending me for the radioactive ultrasound test that they do. They told me to stop taking the levothyroxine until after the test. I guess my question is, how uncommon is it to have a 4cm nodule? Does that make it more likely to be cancer, or less likely? I can not find any links online between the size of a nodule and TSH level. I would appreciate any advice you can lend in this matter. Thank you in advance for your help!
