About Head and Neck Cancer
A diagnosis of head and neck cancer is a life-changing event. Many people find that learning more about the details of their cancer type and treatment gives them a feeling of empowerment and helps them cope with the changes that follow a cancer diagnosis. This website includes detailed articles about specific cancer types, but the information contained on this web site is from research and personal experience and not from medical practitioners and the information should not be used as medical advice. The information contained on this website is general information and should be used as such.
Head and Neck cancers do not attract a lot of publicity. The general population is largely unaware of the causes, symptoms, treatments and consequences of head and neck cancer until they or someone they know is diagnosed with one of these cancers.
Head and neck cancer, and the treatments used to combat it (surgery, radiotherapy and chemotherapy), may have a significant impact on a person’s appearance, ability to eat and/or communicate both short and long term.
What is Head and Neck Cancer?
Head and neck cancer are a general term that refers to a range of different cancers that start developing in the head and neck region of the body. This includes the oral cavity, tongue, palate, jaw, salivary glands, throat (larynx) and the nose.
Most head and neck cancers start in the squamous cells that line the mouth, nose or throat. These are called Squamous Cell Carcinomas (SCCs).
Cancer can occur when abnormal cells grow and spread quickly, forming a mass called a tumour. Tumours can be non-cancerous (benign) or cancerous (malignant). Sometimes cancer cells break away from the original tumour and travel to other areas of the body, where they keep growing and go on to form new tumours. This is called metastasis.
Cancer can occur in any tissue or organ in the head and neck. Head and neck cancer are a term used to describe a range of malignant tumours that can appear in the mouth, throat, larynx (voice box), nose, sinuses and around the eyes. Cancers are treated according to the location of the primary tumour, or where the cancer started in the body. It is important to know the exact medical name of the cancer you have so you can find the right information. The treatment for sinus cancer is not the same as for oropharyngeal cancer, for example. If you are not sure what your cancer is called, you can ask your doctor or nurse to write it down for you.
Incidence Rate
In 2017 the Western Australian incidence rate for Head & Neck Cancer was 584 people. Of those 584 people unfortunately the mortality rate was 115.
In 2019 there were 5,212 new cases of Head & Neck Cancer diagnosed in Australia and this accounts for 3.4% of all cancers diagnosed. That number is expected to increase in 2020. In 2019 it is estimated that there are 17,000 people living with Head & Neck Cancer in Australia.
On the plus side the survivability rate for Head & Neck Cancer has increased from 63% in 2015 to 71% in 2019.
According to Cancer Council statistics, approximately 4,000 Australian people (2,920 men and 1,080 women) are diagnosed with a head and neck cancer each year.
While worldwide, head and neck cancer are the sixth most frequently occurring cancer. Men are two to three times more likely to develop this type of cancer than women. However, the incidence of head and neck cancer in women is now increasing.
Head and neck cancer are most common in people over the age of 40, but there has been a recent increase in younger people developing the disease.
What are the risk factors for Head and Neck Cancer?
A risk factor is any factor that is associated with increasing someone’s chances of developing a certain condition, such as cancer.
Some risk factors are modifiable, such as lifestyle or environmental risk factors, and others cannot be changed, such as genetic or inherited factors.
Having one or more risk factors does not mean that you will develop cancer. Many people have at least one risk factor but will never develop cancer, while others with cancer may have had no known risk factors. Even if a person with cancer has a risk factor, it is usually hard to know how much that risk factor contributed to the development of their disease.
The main factors that are associated with a higher risk of developing head and neck cancer are:
- Smoking and alcohol consumption - Smoking and alcohol consumption are the main risk factors for most types of head and neck cancers, except for salivary gland cancer. Research indicates that at least 75% of head and neck cancers are caused by a combination of cigarette smoking and alcohol consumption.
- Smoking - Smoking cigarettes, cigars or pipes is associated with an increased risk of head and neck cancer, especially of the larynx.
- Alcohol use - Alcohol use may lead to an increased risk especially in heavy drinkers (three or more drinks per day). Smoking and using alcohol greatly increase your risk.
- Infection with some types of human papillomavirus (HPV) (Oral Sex with Females) - Infection with some types of human papillomavirus (HPV), especially for cancers involving the tonsils, the tongue including the base of the tongue, the paranasal sinuses and the nasal cavity.
- Infection with Epstein–Barr virus (the virus that causes glandular fever), for nasopharyngeal cancer and salivary gland cancer.
