Becoming of mouth cavity cancer because of

Although there is no accurate proof showing that single factor will cause the creation of mouth cavity cancer,many researches show that the multiple factor will raise the incidence rate of mouth cavity cancer.The chronic incitement is general accept one of more important reasons, include a machine incitement and chemistry incitement.
The form of chronic incitement contains many kinds, being more subjected to among them chewing a betel nut, smoking cigarette, drinking is advertent, the syphilis, sunlight irradiation and nourishment lack, project a line treatment, bad oral hygiene and mend thing, and occupation...etc. possible reason;Another age, sex and race and geography district will as well influence the incidence rate of mouth cavity cancer.Choose and summarize as follows:
(1)betel nut
Relevant betel nut the relationship with of mouth cavity cancer be widespreadly valued by many scholars recently, in addition to Taiwan, with the mouth cavity cancer incidence rate and death rate the all tallest India but talk, many people as well have the habit that chew the food betel nut more.In addition to mouth cavity cancer, many that love a food betel nuts will as well produce mouth cavity to expect the pathological changes,such as white spot disease, mouth cavity mucosa, descend a fiber to turn before the cancer, the tooth bite to match noodles to seriously wear, tooth week far-gone and serious disease.
(2)tobacco
Smoke as well is the important factor of mouth cavity cancer occurrence, particularly is a cigar smoke and smoke with the pipe.In a research, take out a cigar or get the opportunity right and wrong of mouth cavity cancer to smoke with the pipe it 400%;If smoke more than 35 everyday, then get the opportunity of mouth cavity cancer and take out a cigar or look like with the pipe opportunity to smoke.
Someone thinks tobacco not the start factor of mouth cavity cancer, but have the influence that promote sex on mouth cavity cancer, particularly is smoking and chew the betel nut two kinds of bad habits to all have, permit the "manufacturing" export chamber cancer most ;Discover in another research at smoke of 102 mouth cavities for curing or swallow a cancer, the patient wins, after six years, the one who continue to smoke has 32% occurrence again the second"smoke area" cancer, but stop smoking however 5% delivers the second mouth cavity cancer again.
The one who take out cigar particularly takes out with the pipe, this kind of habitual person also easily suffers from a mouth cavity cancer, particularly is a lips cancer.The person in some places in India is the cigarette or the cigar spark of on carrying and putting and absorbing in the mouth, as a result increase a cancerous incidence rate, this includes nicotian chemical effect among them and also pluses a hot incitement function.Moreover the one who have to chew a tobacco habit, spoil Wu to put tobacco in a certain mastication inside, here will develop a white spot disease gradually, after around 1, 20 but formation cancer.
(3)alcohol
In the Europe and America on taking, strong drink and mouth cavity cancer is germane, 50% mouth cavity cancer sufferers have already drunk to excess a habit;Drink to excess the opportunity of mouth cavity cancer for at times drink it 1500%, but the smoke wine habitually all have the comparison is higher.
Although the alcohol probably has some directly cancer-causing functions,is a more likely to be indirect alcohol to cause cancer function, its function machine becomes not clear.But the alcohol too much then results in cirrhosis' having already had a hard conclusion.
(4)syphilis
Syphilis is result in lips and before the tongue 2/3 part cancer of important factor, the cancer pathological changes mainly blazes to cause because of the syphilis tongue;Once the scholar discovered, in the sufferer of syphilis, 3% has inside before the cancer the pathological changes white spot disease, among them, the white spot disease of 10% finally turned into a mouth cavity cancer.
(5)the sunlight project light upon
The sunlight projects light upon for the lips cancer, particularly is an important factor of the lower lip cancer.Think currently that the sunlight will increase the incidence rate of lower lip cancer, especially farmer, seaman and outdoor worker;And the incidence rate of lips cancer is also more than northern nation in the southern nation.On the other hand, the lips cancer of the black and the incidence rate of the skin cancer are also less than white man, may have protection effect because of its melanin cell to.
(6)the nourishment lack
In regard to women, the serious iron lacks anemic swallow with to glue a film to atrophy and swallow a difficulty relevant allied.Among them at Peterson-Brown-Kelly the sufferer of the symptoms, may also can increase a mouth cavity cancer incidence rate.
Moreover the habit smoke wine betel nut, whether will as well because its decrease normal food it take, but make malnutrition or immunity ability lowered but cause cancer the creation of disease, need further study.
(7)project a line treatment
There are some reports suggesting, the cancer of head neck has been projected line after projecting light upon the treatment when the long term tracks, discover in minority of cases to show the situation of the hair mouth cavity cancer creation once, among them, the knish lump was mostly;May be the mutation that projects line to result in normal cell to.
(8)bad oral hygiene and mend a thing
Many clinical doctors believe that the mouth cavity cancer a little bit often takes place a worse sufferer the body is in the oral hygiene up, but in learning statistics hard proof, because inside most populations or many or little sharp sides that all have decayed tooth and badly mend a thing or split a tooth.
(9)occupation
In addition to outdoor worker, the metal worker contracts the ratio of mouth cavity cancer to seem to be also higher.When the cause of disease that in addition studies a mouth cavity cancer learned, as well need in consideration of the mouth cavity cancer delivers sexually transmitted disease more to change to produce of possibility;Because inside the mouth cavity if have some district to easily deliver a cancer pathological changes, probably also have the quite a few the district to have same impressibility in the meantime;It dissects position to mutually separate, or simultaneous with, or partition a period just take place behind, its incidence rate invite at 6.39-11%.In addition to mouth cavity cancer, the whole stomach and intestines way of deliver sex cancer more to as well have same increment tendency.
