Quick facts about head and neck cancer
Most head and neck cancers begin in the thin, flat cells of the lining of the throat, mouth and nose. These cells are known as squamous cells
Not all tumours in the head and neck are cancerous
Each year more than 5,100 people in Australia are diagnosed with head and neck cancer
Head and neck cancers are more common in people over the age of 40
Types of head and neck cancer
Cancers of the head and neck include the following areas:
-
Mouth (oral cavity)
This includes the lining of lips and cheeks, hard palate and the first two thirds of the tongue, as well as the gums and tonsils
-
Larynx
This is also known as the voice box, and contains the vocal cords used for making sound. The larynx connects the windpipe (tube that connects to the lungs) with the lower part of the throat
-
Pharynx
The pharynx is also known as the throat. Cancer can affect any three areas that make up the pharynx including:
Nasopharynx – This is the upper part of the throat, behind the nose
Oropharynx – This includes the base of the tongue to the tonsils in the back of the throat
Hypopharynx – This is the lower region of the throat, including behind the voice box
-
Nasal cavity and sinuses
The nasal cavity is the area inside the nose. The area behind the nose consists of four sinuses which impact on the sound and tone of speech.
-
Salivary glands
This is where saliva is produced to help digest food and protect against infections. Most of the tumours found here are typically benign (non-cancerous).
Cancers of the brain, thyroid gland, eye and oesophagus are not included in the classification under ‘head and neck’ cancer.

Stages of head and neck cancer
The TNM system is used to stage head and neck cancer, and it helps doctors understand what your cancer looks like. The TNM stands for:
Tumour – Describes the size of the tumour and the extend the cancer has spread
Node – Describes whether the tumour has spread to nearby lymph nodes. Nodes can be graded from N0, where the has been no spread, through to N3, where the cancer has spread to other lymph nodes
Metastasis – Describes whether the cancer has spread to other areas of the body outside of the lung. Metastasis can be graded from M0, where there has been no spread through to M1c, where the cancer has spread to other organs of the body and produced additional tumours.
