Dear friend, welcome and thanks for entrusting your query here at HCM!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
Your doctor has rightly advised you as colloid goiter
with FNAC and scan proven hormonal
inactivity has proved its benign nature.
However enlargement and long term pressure on the underlying air-pipe (trachea0 can later cause problems.
So surgery to relieve pressure is sometimes needed.
Keep a watch on noisy breathing, breathlessness, hoarseness
of voice etc.
Keep regular follow up.
I hope you are fully satisfied with the guidance I gave.
I would be glad to answer any further queries. May I request you to rate your experience here before you close.
Thank you and Good luck!
