Mr Jonathan Bernstein is one of the high volume thyroid cancer surgeons in the UK. Based at The Royal Marsden cancer centre in London, he undertakes routine, complex and reoperative thyroid cancer surgery, in addition to surgery for head and neck malignancies. He also undertakes diagnostics for thyroid nodules. He works in conjunction with leading thyroid oncologist, Dr Kate Newbold at the Royal Marsden. In this article, Mr Bernstein explains the basics of thyroid cancer.

What is the thyroid?

The thyroid is a butterfly-shaped endocrine gland found in the middle of the neck. It is responsible for making thyroid hormone, which is essential for regulating the body’s metabolism.

Most thyroid nodules are benign and not of concern, but cancer of the thyroid gland has been getting more common, probably because of increased detection with imaging. The majority of this increase is accounted for by small, low-risk papillary thyroid carcinomas. Thyroid cancer can also occur in more advanced forms, with a firm mass in the neck or with spread to lymph nodes.

 

Thyroid cancer: 4 top facts

  1. Thyroid cancer is three times more common in women than men.
  2. There are four main types of thyroid cancer: papillary (most frequent), follicular, medullary and anaplastic (least frequent). Lymphoma can also occur in the thyroid but this is very rare.
  3. Thyroid cancer can be more aggressive over the age of 55.
  4. Thyroid cancer accounts for over 3% of all new cancer diagnoses each year.

 

Four types

  1. Papillary thyroid carcinoma – 8 out of 10 thyroid malignancies are papillary thyroid carcinoma. Most papillary thyroid carcinoma is low-risk. When solitary and under 4 cm, this form of thyroid cancer can sometimes be treated by only removing the affected half of the thyroid gland. It is important to tailor the treatment to the individual.
  2. Follicular thyroid carcinoma – 1 out of 10 thyroid cancers are follicular carcinoma. This and the Hurthle cell carcinoma variant can be higher risk.
  3. Medullary thyroid carcinoma – This type of thyroid cancer usually occurs sporadically, but medullary carcinoma can run in families and can be part of a condition called MEN type II.
  4. Anaplastic thyroid carcinoma – This is a fast-growing and very aggressive form of thyroid cancer, accounting for less than 1% of thyroid cancers.

Lymphoma can also be found in the thyroid. Lymphoma is a cancer that develops in the lymph system (part of the immune system).

 

What are the causes of thyroid cancer?

Usually there is no cause to be found for thyroid cancer; thyroid cancer is usually spontaneous. The risk factors associated with thyroid cancers include radiation exposure, a family history of thyroid cancer in a first-degree relative, and certain rare syndromes, such as Cowden syndrome. The incidence is much higher in women than in men.

 

What are the symptoms of thyroid cancer?

Most thyroid cancer, and low-risk papillary thyroid carcinoma in particular, cause no symptoms. Thyroid cancer symptoms can include:

  • A firm lump around the middle of the neck which moves upwards on swallowing
  • Firm lumps in the outer neck
  • Weakness of the voice lasting several weeks

The keys to diagnosis are ultrasound and fine needle aspiration cytology (biopsy). Sometimes a contrast-enhanced CT scan is needed because CT can show more extensive disease very clearly. Radioactive iodine therapy is frequently an essential part of treatment, and radiotherapy can be needed in certain more advanced cases.

Where can I go for thyroid cancer treatment?
