About head and neck cancer

Head and neck cancer is a broad term for a group of cancers that start in the tissues or lymph nodes in the head and neck area. It can affect the mouth, tongue, palate, gums, salivary glands, tonsils, throat, voice box, nose, and sinuses.

While some tumours in this area may be benign (non-cancerous), only malignant tumours are classified as cancer.

Although these cancers are different, they are treated similarly, so are considered as one group.

Around 800 Queenslanders are diagnosed with head and neck cancer each year, with men three times more likely than women to be affected.

Types of head and neck cancer

Head and neck cancers are classified by the area where they begin.

Oral cancer

Cancer that starts in the mouth is called oral cancer. Cancer can begin in any part of the mouth, which is made up of the lips and oral cavity. The oral cavity includes the gums, inside lining of the cheek and lips, front two-thirds of the tongue, floor of the mouth under the tongue, bony roof of the mouth (hard palate), and the small area behind the wisdom teeth. A common treatment is surgery – particularly in the beginning stages of mouth cancer.

Salivary gland cancer

There are three pairs of major salivary glands – the parotid (in front of the ears), sublingual (under the tongue) and submandibular gland (under the lower jaw). There are also hundreds of smaller glands throughout the lining of the mouth, nose and throat. These are known as minor salivary glands. Cancer can start in the major or minor salivary glands.

Throat cancer

Also called the pharynx, the throat is a hollow tube behind the nose leading to the food pipe (oesophagus) and windpipe (trachea). Cancer can occur in the three parts of the pharynx – the nasopharynx, oropharynx, or hypopharynx, but are treated differently. Symptoms of throat cancer can include a dull pain in the neck, difficulty swallowing or opening the mouth wide, a persistent sore throat or cough, or coughing up bloody mucus.

Voice box (larynx) cancer

The voice box, also known as the larynx, is the entryway to the windpipe. The cancer that starts in the larynx is called ‘laryngeal cancer’.

Nasal cavity or sinus cancer

The nasal cavity is the large, hollow space behind the nose. The bones around the nasal cavity have a group of small, air-filled spaces called the paranasal sinuses. Cancer that starts in the upper part of the throat behind the nose is called nasopharyngeal cancer.

Risk factors

Head and neck cancers are linked to a few key risk factors, with smoking and alcohol consumption and infection with the human papillomavirus (HPV) being three of the biggest. When smoking and alcohol consumption are combined, the likelihood of developing these cancers dramatically increases compared to either just drinking or smoking.

Additional risk factors only account for a small proportion of head and neck cancers, and include:

  • A weakened immune system
  • Poor dental health
  • Having persistent sores or red or white patches in the mouth
  • Being overweight or obese
  • Chewing tobacco, betel nut, areca nut, gutka or paan
  • Sun exposure (for head and neck skin cancer)
  • Having had radiation therapy to the head and neck area in the past
  • Inheriting a condition linked to head and neck cancer such as Fanconi anaemia or Li-Fraumeni syndrome
  • Breathing in asbestos fibres, wood dust or certain chemicals
  • Having a parent, child or sibling with head and neck cancer (possibly because you have similar lifestyle factors)

Symptoms

In the early stages, there may not be any noticeable signs and symptoms of head and neck cancer. When symptoms do occur, the most common symptom is a lump in the neck. These symptoms can also occur with other illnesses and do not necessarily mean you have cancer. Only medical tests can confirm a diagnosis.

Seek medical advice immediately if you experience symptoms including:

Mouth (oral) cancers

  • Mouth pain
  • Pain when swallowing
  • A persistent sore or swelling in the mouth, or the area not healing after having a tooth extracted
  • A sore throat that doesn’t get better

  • Red or white patches on the gums, tongue or mouth
  • Bad breath
  • Changes in speech or trouble pronouncing words
  • Difficulty chewing or swallowing food or moving the tongue
  • Weight loss
  • Loose teeth, or dentures that no longer fit
  • Earache

Throat (pharyngeal) cancers

  • A lump in the neck
  • A persistent sore throat or cough
  • Difficulty swallowing or opening the mouth wide
  • Coughing up bloody mucus
  • Bad breath
  • Weight loss
  • Voice changes or hoarseness
  • Dull pain around the neck
  • Earache
  • Feeling that your air supply is blocked
  • Numb face
  • A blocked nose
  • Hearing loss
  • Headache

Voice Box (laryngeal) cancers

  • A persistent change in the sound of your voice, including hoarseness
  • A sore throat that doesn’t get better
  • Difficulty swallowing or pain when swallowing
  • Coughing all the time
  • Difficulty breathing
  • Weight loss
  • Pain in the ear

Nose (nasal cavity of sinus) cancers

  • Reduced sense of smell
  • A persistent blocked nose or ear
  • Frequent nosebleeds
  • Lots of mucus in the throat or back of nose
  • Frequent headaches or sinus pressure
  • Difficulty swallowing
  • Loose or painful upper teeth
  • A lump on or in the face, nose or mouth
  • Numb face, upper lip or inside mouth
  • Pressure or pain in ears
  • A bulging or watery eye
  • Double vision or complete or partial loss of eyesight

Salivary gland cancers

  • Swelling or a lump near the ear, jaw or lip, or inside the mouth
  • Left and right sides of the face or neck looking different (asymmetry)
  • Drooping, numbness or muscle weakness on one side of the face (palsy)

Diagnosis

If you have concerns, chat to your doctor immediately. You may also mention issues such as mouth sores, swelling or a change of colour in your mouth to your dentist as they are also trained to look for signs of mouth cancer. Your GP or dentist may refer you to a specialist.

Depending on your symptoms, diagnosing head and neck cancer may involve:

  • Physical examination: Your doctor will examine your mouth, throat, nose, neck, ears and/or eyes.
  • Endoscopy: Often used to investigate nasal, larynx and throat cancer symptoms, it involves an examination of the nose and throat area using a thin, flexible tube with a light and camera on the end.
  • Microlaryngoscopy: Performed under general anaesthetic, this allows your doctor to examine your throat and voice box and take a tissue sample (biopsy).
  • Biopsy: Involves removing a sample of cells or tissue from the suspicious sore or lump to check for cancer cells under a microscope.
  • Imaging Tests: such as a CT scan, MRI Scan, PET-CT scan, Ultrasound or X-ray

Waiting for your test results and receiving a diagnosis can be a stressful time. It’s normal to feel a range of emotions. It may help to talk to a friend or family member, a healthcare professional, or call Cancer Council Queensland on 13 11 20.

Treatment

There are a range of treatment options for head and neck cancer, including surgery, radiation therapy, chemotherapy and immunotherapy. These may be used individually or in combination. Your treatment plan will depend on the type, location and stage of the tumour, your general health.

Types of treatment explained

  • Surgery: Removes cancer or repairs a part of the body affected by cancer, it is often used as the main treatment for head and neck cancer.
  • Radiation Therapy: uses targeted radiation to kill or damage cancer cells; sometimes used as the main treatment for head and neck cancer
  • Chemotherapy: Uses drugs to kill cancer cells or slow their growth; usually combined with radiation therapy, which is known as chemoradiation.
  • Targeted therapy: targets specific cancer cell features to stop the cancer growing or spreading
  • Immunotherapy: uses your own immune system to fight cancer.
  • Palliative care: Focuses on improving quality of life by relieving symptoms without trying to cure the disease. It can help manage pain and symptoms and may also slow the spread of cancer.

Prognosis

When we talk about prognosis, we’re talking about the likely or expected outcome of the disease. It is important to remember that not even an expert can predict the exact way a disease will progress. Earlier diagnosis usually leads to better outcomes, but even advanced cases may respond well to treatment.

Factors influencing your prognosis include test results, the type of the cancer, its HPV status, the rate and depth of the cancer’s growth, how likely the cancer is to respond to treatment and other factors such as your overall health, age and level of fitness.

Talking about prognosis and the future can feel stressful. Sharing your concerns with loved ones or seeking support can help. If you’d like more information or some emotional support, you can call Cancer Council Queensland on 13 11 20.

Questions you might have

How is head and neck cancer diagnosed?

An appointment with your GP or dentist is your first step if you have concerns or symptoms that may be related to head and neck cancer. They will perform an initial physical examination and may order further tests. You may also be referred to a specialist.

Diagnostic tools or methods that may be used include an endoscope, surgery, or a needle biopsy, X-Ray, CT scan, MRI or PET-CT scan.

Is an itchy neck a sign of cancer?

An itchy neck is not a typical symptom of head and neck cancer, but if you have symptoms that are unusual for you, it is worth having them checked out by a doctor.

What does throat cancer look like?

In their early stages, head and neck cancers may have no symptoms. When symptoms do occur, the most common symptom is a lump in the neck (caused by cancer that has spread to a lymph node). Other symptoms will depend on the type of head and neck cancer.

How to check for throat cancer at home?

It is important to know what is normal for you, and if you notice anything that has changed, see your doctor. Some things to watch out for include difficulty or pain when swallowing, pain in the ears, a persistent sore throat or cough, headaches or earaches.
