Head and neck cancer is a general term for a range of cancers that start
in the tissue or lymph nodes in the head and neck area.
• The main risk factors for head and neck cancer are drinking alcohol and
using tobacco.
• Human papilloma virus (HPV) can increase the risk of cancers in the
tongue, tonsil, and throat (oropharynx).
• The symptoms of head and neck cancer can be different from person to
person. It is important to have your GP or whānau doctor check any
symptoms:
     • A lump (or lumps) in the neck can be the first sign of head and neck
     cancer. These lumps are generally painless and may slowly get bigger.
     • Some head and neck cancers cause pain, coughing, or changes in
     swallowing, hearing, vision, or speaking.

What is head and neck cancer?

Head and neck cancer is a general term for a range of cancers that start in the
tissue or lymph nodes in the head and neck area. It includes cancers of the:
• mouth
• tongue
• throat (nasopharynx, oropharynx, and hypopharynx)
• voice box (larynx)
• nose and sinuses
• salivary glands
• skin of the head and neck (including the scalp and ear)
• thyroid.
Cancer that starts in the brain, eye, oesophagus (food pipe), or bones of the head/spine is not usually considered head and neck cancer.
In this booklet, head, neck, and mouth cancer are referred to as head and neck cancer.

How head and neck cancers get their names

Head and neck cancers are named after the part of the body where they start.

Cancer that starts in the mouth is called oral cancer. The mouth includes the lips, tongue (the front bit you can see), gums, cheeks, roof of your mouth (hard palate) and floor of your mouth (under your tongue).

The tongue has two parts:
• The part you can see (the oral tongue)
• The part that disappears into the back of your throat and that you cannot see (the base of the tongue)
Cancer on the part of the tongue that you can see is called oral cancer.
Cancer on the part of the tongue that you cannot see is called oropharyngeal cancer.

The throat (pharynx) has three main parts:
• Nasopharynx
• Oropharynx
• Hypopharynx

Nasopharynx:

The nasopharynx is the top part of the throat that starts behind the nose. Cancer that starts in this space is called nasopharyngeal cancer.

Oropharynx:

The oropharynx is the middle part of the throat that starts behind the mouth. It includes the soft part of the roof of the mouth (soft palate), the part of the tongue you cannot see (tongue base), the tonsils, and the back and side walls of the throat. Cancer that starts in this space is called oropharyngeal cancer. Many oropharangeal cancers are linked to the Human Papilloma Virus (HPV).

Hypopharynx:

The hypopharynx is the bottom part of the throat that sits behind the voice box (larynx). Cancer that starts in this space is called hypopharyngeal cancer.

Laryngeal cancer affects the larynx. Your larynx is more commonly called your voice box and has two vocal cords inside. When the air you breathe moves past the vocal cords they vibrate—this is how you make different sounds when you speak.

The larynx sits near the entrance to your airway (trachea) in your neck. The epiglottis acts as a flap to cover the trachea when you swallow. This stops the food you eat and drink entering your lungs.

The larynx has three parts:
• Supraglottis—the space above the vocal cords
• Glottis—the middle of the larynx where the vocal cords are
• Subglottis—the space below the vocal cords that attaches to your airway

Cancer that starts inside the nose or in the paranasal sinuses is called nasal and sinus cancer.

The space inside the nose is called the nasal cavity. This space warms, moistens, and filters the air that you breathe.

The bones around the nasal cavity have small, hollow spaces in them called paranasal sinuses. The sinuses affect the tone and sound of your voice.

There are usually four pairs of paranasal sinuses (some may be missing or not fully developed):

• Frontal sinuses—behind the forehead
• Ethmoid sinuses—above the nose and between the eyes
• Sphenoid sinuses—behind the nose and between the eyes
• Maxillary sinuses—under the eyes and in the cheek area

Cancer that starts in any of the salivary glands is called salivary gland cancer.
The salivary glands make saliva (spit), which keeps your mouth moist and makes it easier to swallow food.

There are three main pairs of salivary glands:

• Parotid glands—on each side of the mouth, in front of the ears
• Sublingual glands—under each side of the tongue
• Submandibular glands—under each side of the jawbone

There are many smaller glands in the lining of the mouth and throat. These are known as the minor salivary glands. Most salivary gland cancers start in the parotid glands.

New Zealand has a very high rate of both melanoma and non-melanoma skin cancer. The head and neck area is commonly affected due to regular exposure to the sun, often without any skin protection.

Some skin cancers can spread (metastasise) to other parts of the head and neck, such as the lymph nodes and the parotid gland.

The thyroid gland is located low in the central neck, below the voice box (larynx) and in front of the windpipe. It produces a hormone called thyroxine. Thyroxine helps to regulate your weight, body temperature, growth, and development.

Cancers that start in the thyroid gland are often lower grade and grow more slowly than other head and neck cancers. There are some higher-grade, faster-growing types of thyroid cancer, but these are rare.

Types of head and neck cancer

Cancers of the head and neck are also named by the type of cell where the cancer first started to grow.

 

     
Squamous cell
carcinoma (SCC)
Cancer that starts in the
cells that line the surfaces of
the mouth, nose, throat or
skin.

Most common

(90%)

Lymphoma Cancer that grows in the
lymphatic system (immune
system) and travels to your
lymph nodes in your
head and neck.

Common

information on

Melanoma Cancer that grows in the
cells that give colour to your
skin and eyes. Melanoma can
also start in the cells that
line the mouth.
Uncommon
See more
information on

Adenocarcinoma Cancer that starts in the
glands of the head and neck.
Rare
Sarcoma Cancer that grows in the

muscles in the head and
neck.

What are the risk factors for head and neck cancer?

Anything that can increase your chance of developing cancer is called a risk factor.

Some risk factors can be changed, such as not smoking. Some risk factors cannot be changed, such as having a strong family history of cancer.

Having one or more risk factor does not mean that you or your whānau will develop cancer. Most people have at least one risk factor but will never develop cancer. Others with cancer may have no known risk factors.

Risk factors that we know make some people more at risk than others for head and neck cancer include the following:

  • Chewing tobacco or betel nut (araca and gutka) increases the risk
    of developing mouth cancer.
  • Contact with certain chemicals and dusts through workplaces can
    increase the risk of throat cancer (oropharyngeal).
  • Head and neck cancers are more common in men than in women.
  • Head and neck cancer is more common in people over the age of
    50. However, younger people can be affected too.
  • HPV can increase the risk of cancers in the tongue, tonsil, and
    throat (oropharynx).
  • If you drink a lot of alcohol (more than 10 standard drinks a week)
    you increase your risk of developing head and neck cancer.
    If you smoke and drink alcohol, the risk is even greater.
  • Smoking tobacco is the number one risk factor for head and neck
    cancer. It includes smoking cigarettes, cigars, and pipes. The more
    you smoke, the greater the risk.
    People who do not smoke can also get head and neck cancer, but
    their risk is much lower.
    The long-term health impacts of vaping are unknown.

 

Symptoms of head and neck cancer

The symptoms of head, neck, and mouth cancer depend on where the cancer is. In its early stages, head and neck cancer may have no symptoms. Cancer that begins in the head or neck usually spreads to lymph nodes in the neck before it spreads elsewhere.

A lump (or lumps) in the neck can be the first sign of cancer of the mouth, nose, throat, voice box (larynx), or thyroid gland. These lumps are generally painless and may slowly get bigger. Some people feel very tired (fatigue) when cancer is growing.
