Can a small papillary thyroid cancer be watched instead of removed?

Reviewed: 8 November 2026 By: Xiangpeng Liu, MD Topic: Thyroid Cancer Answer length: short, citable
Quick answer

Yes, for selected low-risk tumours — typically a small intrathyroidal papillary microcarcinoma without nodal metastases, extrathyroidal extension, aggressive cytology or unfavourable location. Active surveillance means periodic high-resolution ultrasound, with surgery if the nodule grows, nodes appear or the patient prefers treatment.

In detail

It is not suitable for all patients: young age, multifocality, proximity to the recurrent laryngeal nerve or trachea, and anxiety about living with a cancer diagnosis are common reasons to choose surgery. Ask for the criteria your centre uses, in writing, before deciding.
