Head and neck cancers


Diagnosing head and neck cancers

Page last updated: February 2024

Expert content reviewers:


Tests to diagnose head and neck cancers include biopsies (testing tissue samples) and imaging tests such as ultrasound, CT and MRI scans.

If you notice any symptoms, arrange to see your GP. You can tell your dentist about any mouth sores, swelling or change of colour in your mouth, as they are trained to look for signs of mouth cancer.

Your GP or dentist may do some general tests and then refer you to a specialist.

Your guide to best cancer care

A lot can happen in a hurry when you’re diagnosed with cancer. The guide to best cancer care for head and neck cancer can help you make sense of what should happen.

It will help you with what questions to ask your health professionals to make sure you receive the best care at every step.

Physical examination

Depending on your symptoms, the doctor will examine your mouth, throat, nose, neck, ears and eyes. They may gently press your tongue down to check the mouth or feel the area with a gloved finger. They will also feel your neck to check the lymph nodes.

For hard-to-see areas, the doctor may use specialised equipment (endoscopy), or suggest a procedure under anaesthetic (microlaryngoscopy) to fully examine the area. They may also remove a tissue sample to test (biopsy).

Imaging tests

Imaging tests give more details about where the cancer is and whether it has spread to other parts of your body. You will usually have at least one imaging test done before a biopsy is done.

Before having scans, tell the doctor if you have any allergies or have had a reaction to dyes during previous scans. You should also let them know if you have diabetes or kidney disease, or are pregnant or breastfeeding.

Staging head and neck cancers

Working out how far the cancer has spread is called staging. It helps your doctors recommend the best treatment for you.

In Australia, the TNM (tumour–nodes–metastasis) system is the method most often used for staging head and neck cancers. In this system, each letter is assigned a number to describe the cancer.

Based on the TNM numbers, the doctor then works out the cancer’s overall stage on a scale of 1–4.

Each type of head and neck cancer is staged slightly differently, and oropharyngeal cancers are staged differently depending on whether they are linked to HPV. In general:

  • stages 1–2 mean the cancer is small and hasn’t spread from the primary site (early head and neck cancer).
  • stages 3–4 mean the cancer is larger and has spread (advanced head and neck cancer). It may have spread to nearby tissue or lymph nodes (locally advanced cancer) or to other parts of the body (metastatic cancer).

Ask your doctor to explain what the stage of the cancer means for you.

Prognosis

Prognosis means the expected outcome of a disease. You may wish to discuss your prognosis and treatment options with your doctor, but it is not possible for anyone to predict the exact course of the disease.

Instead, your doctor can give you an idea about the general outlook for people with the same type and stage of cancer as you.

To work out your prognosis and advise you on treatment options, your doctor will consider:

  • your test results
  • the type of head and neck cancer
  • your smoking history
  • the cancer’s HPV status (if relevant)
  • the rate and depth of the cancer’s growth
  • the likelihood of response to treatment
  • other factors such as your age, level of fitness and overall health.

In most cases, the earlier head and neck cancer is diagnosed, the better the outcome, but people with more advanced head and neck cancer may also respond well to treatment. Oropharyngeal cancers linked with HPV also usually have better outcomes.
