Thyroid Cancer

Personalised treatments designed to fight cancer while minimising side effects.

What is Thyroid Cancer?

Thyroid cancer develops in the thyroid gland, a small butterfly-shaped organ located at the base of the neck. The thyroid produces hormones that regulate metabolism, heart rate, and body temperature. When abnormal cells in the thyroid grow uncontrollably, they may form nodules or tumours, which can be benign or malignant. Malignant nodules are considered thyroid cancer and require further evaluation and treatment.

How Common is Thyroid Cancer in Singapore?

According to GLOBOCAN 2020, thyroid cancer is among the top 10 cancers in women in Singapore, with over 800 new cases diagnosed annually. It is more common in women than men and often occurs between the ages of 30 and 60.

Signs and Symptoms of Thyroid Cancer

Thyroid cancer may not cause obvious symptoms in its early stages. Some signs and symptoms include:

How is Thyroid Cancer Diagnosed?

Evaluation of suspected thyroid cancer often includes:

  • Neck examination to detect lumps or nodules
  • Ultrasound imaging to assess nodules and surrounding structures
  • Fine needle aspiration (FNA) biopsy to test if a nodule is cancerous
  • Blood tests to measure thyroid hormone levels and thyroid-stimulating hormone (TSH)
  • CT scans or PET scans in selected cases to evaluate spread

Causes and Risk Factors of Thyroid Cancer

While the exact cause is not always clear, certain factors increase risk:

Types of Thyroid Cancer

Papillary thyroid cancer

The most common type, usually slow-growing and treatable

Can spread through the bloodstream to lungs or bones

Less common, can be hereditary, requires genetic testing

A rare but aggressive type that grows rapidly and is more difficult to treat

Stages of Thyroid Cancer

Staging depends on the size of the tumours, whether it has spread to nearby lymph nodes, and if it has metastasized to distant organs:

Localized disease in the thyroid

Spread to nearby lymph nodes or tissues

Spread to distant organssuch as the lungs or bones

Thyroid Cancer Treatments

Treatment is personalised based on type, stage, and patient profile:

Surgery

The main treatment, involving partial or total thyroidectomy, sometimes with removal of nearby lymph nodes

External beam radiation therapy

May be used in selected advanced cases

Thyroid hormone therapy

Lifelong medication to replace hormones and suppress cancer recurrence

Regular follow-up with imaging and blood tests (e.g., thyroglobulin monitoring) is essential after treatment.
