Head and Neck Cancers

Head and Neck Cancers

Cancers of the head and neck are quite common with a range of different cancers a person can develop. The cancers that affect the head and neck often begin in the squamous cells that line the moist, mucosal surface inside the head and neck, cancer cells can also develop in the salivary glands, however, this is quite uncommon.

When cancers develop in the squamous cells, it’s often referred to as squamous cell carcinomas. Often, cancers of the head or neck are often categorised by the area in which they develop.

Oral Cancer

Oral or mouth cancer can develop anywhere on, or in the mouth. Lips, tongue, floor of mouth and inside the cheek are the most common places for oral cancer.

Throat Cancer

Doctors use different names to describe the area in which the cancer affects such as:

  • – Cancer of the Nasopharynx- the Highest part of the throat behind the nose
  • – Cancer of the Oropharynx- Part of the throat directly behind the mouth
  • – Cancer of the Larynx- Better known as the ‘voice box’, this is the second most common head and neck cancer

The use of alcohol and tobacco are the two biggest risk factors for head and neck cancers causing an estimated 75% of cases.

Other risks are:
