Head and Neck Cancer

There are various types of head and neck cancers. The risk of developing these cancers are more for patients who are exposed to certain environmental factors or it depends on individual lifestyles such as tobacco, and alcohol consumption. 85% of head and neck cancers are due to tobacco and alcohol. People infected with the papillomavirus (HPV) have a higher risk of throat and mouth cancers.

Very common intraocular cancers in adults are melanoma and lymphoma and in children, it is retinoblastoma which starts in the cells of the retina.



Risk factors for head and neck cancer are:

Tobacco smoking is the largest risk factor for head and neck cancer. Secondhand smoke will also increase cancer risk. Tobacco chewing is related to mouth cancer or oral cavity cancer. Excessive alcohol consumption is another largest factor for cancers related to mouth, pharynx, larynx, and esophagus. Men are more likely to get affected than women to develop these cancers. Age also plays an important role; these type of cancers affect people who are above 50 years. Certain types of illness are also related to head and neck cancer such as Epstein-Barr virus (EBV), HPV and two inherited genetic syndromes are Fanconi anemia and dyskeratosis congenital. Long hours of sun exposure may cause lip and oral cancer. Radiation therapy given in high doses particularly done in the head or neck region may increase the risk of developing cancer. Poor nutrition and vitamin deficiency will increase cancer risk.
