Most thyroid nodules are benign, but risk is not determined by size alone. Ultrasound features, TSH, symptoms and possible biopsy are considered together.
A single 1–1.5 cm biopsy threshold does not apply to every nodule. Suspicious lymph nodes, appearance and clinical history change decisions. Benign nodules can still cause pressure or hormone problems. Surveillance, further tests or surgery depend on cytology and clinical context; no 100-percent cure promise applies to all cancers. Report voice change, rapid growth or swallowing and breathing difficulty.
Assessment considers the lump's location, duration and growth. Ultrasound, needle sampling or contrast CT/MRI are selected according to risk; not every lump needs the same operation. Suspected cancer requires multidisciplinary assessment.
In adults, promptly assess a neck lump unexplained by infection that persists for two weeks or has an uncertain duration. Breathing difficulty, rapid growth or swallowing difficulty needs more urgent assessment.
This information does not replace an individual consultation. Diagnosis and treatment depend on a medical assessment.
