Thyroid Cancer Follow-up
After treatment for thyroid cancer, structured follow-up aims to confirm remission, detect any recurrence early and keep hormone replacement well balanced. Follow-up continues for years, with intervals widening as time passes.
This service provides organised long-term surveillance for thyroid cancer survivors.

What follow-up involves
Follow-up combines clinical review, thyroid function testing to keep replacement and TSH suppression on target, tumour markers such as thyroglobulin, and periodic neck ultrasound. Further imaging is arranged if there is concern.
The intensity of follow-up is matched to the risk of recurrence, being more frequent in higher-risk disease.
Monitoring for recurrence
Thyroglobulin is a sensitive marker for differentiated thyroid cancer — a rising level can signal recurrence before it is visible on scans. Neck ultrasound looks for abnormal lymph nodes or changes in the thyroid bed.
Depending on the initial stage, whole-body scanning may be used at intervals.
Living well after treatment
Follow-up also addresses the long-term effects of treatment: keeping hormone levels comfortable, monitoring bone and heart health if TSH is suppressed, and providing reassurance and clear information.
As the risk of recurrence falls, follow-up intervals are usually extended and TSH targets relaxed.
Frequently asked questions
How long does follow-up last?
Usually for many years, often lifelong at longer intervals. The schedule is individualised to the cancer type, stage and response to treatment.
What is thyroglobulin monitoring?
Thyroglobulin is a protein made by thyroid cells and a sensitive marker for differentiated thyroid cancer. A rising level can indicate recurrence.
Can follow-up be done remotely?
Some aspects can, particularly reviewing results, but neck ultrasound and examination need to be done in person at intervals.
