I have a 2 cm thyroid nodule. my doctor is willing to remove it without a gna what're the risks and complications of taking out part of my th?

Some: But not many. You will do just fine if they remove a small amount of tissue. If they have to remove all of it, you may need thryroid replacement but that is a simple thing for your doctor to follow and prescribe.

Why remove?: Surgery has a long list of potential complications particularly around the thyroid. Most nodules are harmless, but fna is necessary to help determine that. Having a 2cm thyroid nodule is not reason enough for surgery unless it looks suspicious for some reason. Please see an endocrinologist. Most 2 cm nodules can just be followed over time provided they aren't suspicious.
