The symptom of mouth cavity and throat cancer

What lead to larynx cancer and mouth cavity cancer?


Larynx cancer and mouth cavity cancer are more familiar in the male and the old people and the cause be not clear.But smoke cigarette and drink more severe person, especially these two kinds of habit include of person, the opportunity to suffer from these two kinds of cancers wants to greatly have to be many.The person who smokes cigarette or absorbs pipe, suffer from tongue cancer and cheeks cancer of the probability also greatly has to be many.In the nation of the widespread mastication tobacco and the betel nut, the outbreak rate of larynx cancer and mouth cavity cancer is very high.The nose back contains a district and call the nose swallow.The nose swallows a cancer very widespread in Chinese the south and Hong Kong, this may be because of 1 kind to call the moxa Pu Tan-Ba Er3 what virus lead to.Although this kind of cancer is more familiar on male and old man's body, it may also occurrence on child and adult's body.


The symptom of mouth cavity and throat cancer


Cancer cell's appearing main symptom is in the mouth cavity or the throat to appear ulcer or lump, usually keep on for a few weeks and generally say that come, these ulcer or lump will not result in ache, but some people will feel painful, may also bleed.Even at do not appear any symptom before, the dentist might also notice phenomenons, such as lump and ulcer...etc. while have the tooth routine check.


The problem that these tumors bring often because of appear of place dissimilarity but is different from.If the tip of the tongue is subjected to an infection, will result in pronunciation not clear;If take place in other places of the mouth cavity or the larynx, then will result in to swallow a difficulty.


Another a the symptom of importance of throat and mouth cavity cancer are the lymphoid swelling of gland of the neck big.The lymphatic gland is a lymphoid system of a part, is the natural guard that the human body resists an infection.The lymphoid system constitutes to°from the small lymphatic gland of a series and mainly distribute in neck, armpit and stomach ditch.It is made the leukocyte help of body by the lymphatic gland to resist infection and disease.The lymphatic gland of neck is usually the place that throat cancer and mouth cavity cancer spread first.Some time, the first symptom of throat and mouth cavity cancer is these have no painful lymphatic gland of swollen big, so, when lymphoid swelling of gland is big, should seek a doctor a check, but please to tightly record, many lymphoid swelling of glands greatly is because of other virus infection with the result that, relate to cancer not necessarily.

The research discover that the zinc can prevent°from esophagus and mouth cavity cancer

Recently, the researcher of American hero Fei in Philadelphia, lousy medical college and Kimmel cancer center discover that the zinc can have already helped esophagus and mouth cavity cancer of prevent°from the high Wei individual.Mouth cavity and esophagus cancer have something to do with nourishment zinc lack, and the Mao COX-2 ascension of expression also mutually contact with these cancers.The Louise Fong wait for someone to discover that letting the big rat of lack the zinc take orally zinc can repress a develop of esophagus and the mouth cavity ex- cancer form and still lowered the expression level of COX-2 in the meantime.

These detections express that the complement of zinc may prevent°from the development of esophagus or mouth cavity cancer, these cancers lack in the zinc of the developing country be an outstanding problem.The researcher announce these detections are on the Cancer Institute of the National of the Journal of in January 5, 2005.

The zinc that the mankind absorb usually comes from red meat and seafood article.However, lack zinc about the food of 10% Americans, but then have about 2,000,000,000 people to lack zinc in the developing country.The Epidemiology studies the enunciation recent some years, esophagus and the mouth cavity cancer outbreak rate to be placed in to continuously rise of trend.And, about there are 13000 Americans dying in esophagus and mouth cavity cancer annually.

The Fong Doctor has been concentrate on to study zinc to lack cancerous with esophagus with it of contact, and set up zinc to lack with the animal model of the cancer sensitivity.The zinc lacks the cell that will increase esophagus and mouth cavity to expand and make thus these districts are to the carcinogen sensitive, so increased the risk of cancer development.

The Fong Doctor lacked esophagus and tongue of big rat to organize medium egg whites COX-2s and gene to express a circumstance to carry on a comparison to the normally big rat and the zinc.They discover that the zinc lacked the COX-2 expression level of big rat to increase 10-1500%.The cell expand the level also increases in the meantime.After letting to lack the zinc big rat to take zinc, the expression of COX-2 shows Zhao to lower and the ex- cancer cell propagated to also take place to converse.The researcher also discovers to use depressant COX-2 the big rat of the processing, it COX-2 and cell propagated levels to all descend.

Experimented a certificate a zinc treatment to recover many systems being lack by zinc to influence.Connect down, the researcher return will investigate zinc and low quantity of celcoxib(the living creature note:Depressants COX-2)unite usage's prevention effect for digest way cancer.
