Frequently asked questions
Does a goitre always need surgery?
No. Many are small and just monitored, or treated by fixing the thyroid problem. Surgery is for large glands, pressure symptoms or suspicion of cancer.
Is a goitre dangerous?
Most are not, but a growing lump, swallowing or breathing trouble, or a hard fixed lump needs prompt assessment to rule out serious causes.
