The Nodule On My Thyroid Is Over 1 Cm And

The nodule on my thyroid is over 1 cm and biopsy shows it's the fellicular type (hope I have that word/sp correct). Surgery to remove half the tyroid is recommended due to this type, size and that this type has a 15% chance of milignancy. I suppose I'd rather know and be gone with it even if it proved out to be benign than live with the what if. So, I wonder then, what will life be like with half a thyroid? What difficulties may I expect if any? Presently, I have just been diagnosed with hypothyroidism. thank you.
