Hi there, I hope somebody can give me a bit of enlightenment, my left side of thyroid is swollen (right side taken out in 2004 due to adenoma) my blood tests are still showing up as normal so I'm neither under or over active. I'm waiting to hear from the endocrine clinic. My question is, is the growth more likely to be another adenoma.. I was told it could happen in 2004 or am I worrying unnecessarily? Many thanks.
