Head & Neck Cancer

Head and neck cancers are a broad category of cancers that occur in the head and neck region.
Head and neck cancer treatment depends on the type, location and size of your cancer. Treatment for head and neck cancers often involves surgery, radiation therapy and chemotherapy. Treatments may be combined.
After treatment, recovery from head and neck cancers may involve working with rehabilitation specialists and other experts to cope with side effects, such as hearing loss, difficulty eating, dental problems, thyroid issues, difficulty breathing or difficulty speaking.


Symptoms -

Head and neck cancer can be hard to diagnose, because symptoms are often mild and can mimic less serious conditions such as a cold or sore throat. These symptoms include:
- A mouth or tongue sore that does not heal.
- A white or red patch on the gums, tongue, or lining of the mouth.
- A persistent sore throat.
- Hoarseness.
- Swelling in the jaw, neck or side of the face. This may cause dentures to fit poorly.
- Frequent sinus infections that don’t respond to antibiotics.
- Neck pain that won't go away.
- Frequent headaches.
- Pain in the upper teeth.
- Bleeding through the nose or in the mouth, or blood in the saliva.
- Trouble swallowing.
- Persistent earaches.
- Trouble breathing or speaking.

If you notice any of these symptoms, it is important to check with your physician immediately. They may be signs of less serious conditions, but a thorough exam should be done.



Causes -

Alcohol and tobacco use (including smokeless tobacco, sometimes called "chewing tobacco" or "snuff") are the two most important risk factors for head and neck cancers, especially cancers of the oral cavity, oropharynx, hypopharynx, and larynx. At least 75% of head and neck cancers are caused by tobacco and alcohol use. People who use both tobacco and alcohol are at greater risk of developing these cancers than people who use either tobacco or alcohol alone. Tobacco and alcohol use are not risk factors for salivary gland cancers.
Infection with cancer-causing types of human papillomavirus (HPV), especially HPV type 16, is a risk factor for some types of head and neck cancers, particularly oropharyngeal cancers that involve the tonsils or the base of the tongue. In the United States, the incidence of oropharyngeal cancers caused by HPV infection is increasing, while the incidence of oropharyngeal cancers related to other causes is falling.

Other risk factors for cancers of the head and neck include the following:
1) Paan (betel quid) - Immigrants from Southeast Asia who use paan (betel quid) in the mouth should be aware that this habit has been strongly associated with an increased risk of oral cancer.

2) Preserved or salted foods - Consumption of certain preserved or salted foods during childhood is a risk factor for nasopharyngeal cancer.

3) Oral health - Poor oral hygiene and missing teeth may be weak risk factors for cancers of the oral cavity. Use of mouthwash that has a high alcohol content is a possible, but not proven, risk factor for cancers of the oral cavity.

4) Occupational exposure - Occupational exposure to wood dust is a risk factor for nasopharyngeal cancer. Certain industrial exposures, including exposures to asbestos and synthetic fibers, have been associated with cancer of the larynx, but the increase in risk remains controversial. People working in certain jobs in the construction, metal, textile, ceramic, logging, and food industries may have an increased risk of cancer of the larynx. Industrial exposure to wood or nickel dust or formaldehyde is a risk factor for cancers of the paranasal sinuses and nasal cavity.

5) Radiation exposure - Radiation to the head and neck, for noncancerous conditions or cancer, is a risk factor for cancer of the salivary glands.

6) Epstein-Barr virus infection - Infection with the Epstein-Barr virus is a risk factor for nasopharyngeal cancer and cancer of the salivary glands.

7) Ancestry - Asian ancestry, particularly Chinese ancestry, is a risk factor for nasopharyngeal cancer.
