Thyroid cancer

Trustworthy information about thyroid cancer, including diagnosis, treatment, side effects and wellbeing

Overview

The thyroid is a small, butterfly-shaped gland at the front of the neck. It makes hormones that help control how your body uses energy. 

Thyroid cancer begins when abnormal cells grow out of control. The most common types are papillary thyroid cancer and follicular thyroid cancer. These cancers usually grow slowly and can be successfully treated. 

A thyroid cancer diagnosis can come as a shock. Find helpful information in Just diagnosed, or call Cancer Connect on 13 11 20 to talk it through with our qualified professionals.
