The causes of oral cancer


Oral and oropharyngeal cancer affects close to fifty four thousand individuals (out of which approximately thirteen thousand four hundred lose their lives to it) in the United States of America alone. In most cases, it is discovered in the later stages of its development and thus is a great cause of distress. There are several causes of oral cancer that must be known to aid timely prevention of the condition.

One of the major biological causes of the cancer, apart from bacteria and fungi, is HPV16 or the human papilloma virus number 16, which is responsible for the creation of carcinogenic cells in the oral cavity. HPV16 is the causative agent of the cancer among young non-smoking victims and can also be transmitted sexually. A diet low in nutrition, especially avoiding fruits and vegetables, can be a cause of developing an HPV16 infection.

Age, resulting in a weak immunity(or having an immunity rendered weak due to certain medications like the blood pressure drug "hydrochlrothiazide" in the past), is yet another cause. An individual having the skin disease lichen planus, graft-versus-host disease(GVHD) or certain inherited conditions of the blood is more likely to develop this cancer. The physical factors that may induce the condition are an esxposure to ultraviolet radiation or X-rays. This is the case with individuals exposed to sunlight for several hours, multiple radiographs (say, at the dentist) for a long period of time or those who regularly use certain sunscreen creams. The causes of oral cancer, recognizable or unknown, need to be addressed so as to avoid trying circumstances in the future with efficiency and ease.
