Oral cancer is a malignant tumor in the oral, collectively, can occur in any part of the oral cavity including the lips, tongue, mouth floor, buccal mucosa, gums, and palate ace tabular bone teeth after area site. Among them, the most common oral mucosal epithelial cell carcinoma after squamous cell carcinoma, the ratio is over 90%, other malignancies, including lymphoma, melanoma, sarcoma, are rare.
Occupies a very high proportion of oral cancer in men cause of death, and smoking, bad habit of drinking has a close relationship. Carcinogenic factors in tobacco are a chemical substance benzopyrene. Tobacco carcinogens, especially oral cancer and lung cancer has almost become conclusive. Is generally believed that long-term smokers, the likelihood of cancer is much higher than non-smokers; prone to lung cancer, smoking cigarettes, smoking bucket, cigars or chewing tobacco cause mouth cancer; alcohol because of its toxicity to normal cells damage the liver and immuno-suppression increases the risk of oral cancer, its incidence increased with increasing alcohol consumption.
More serious is that alcohol and tobacco are the hobby that are at higher risk of oral cancer, 2 to 3 times higher than the single, tobacco or alcohol. Generally considered the possibility of smoking more than 1 pack / day or drinking more than 25 g / day who, suffering from oral cancer or other parts of the cancer is Night toothache what is the reason much higher than the non-smoking non-drinkers.
The long-term nutritional deficiencies, poor oral hygiene, sharp tooth decay, and root and produced inappropriate or broken prosthesis (such as dentures, cap, etc.) cause chronic damage to the tongue, gums or pharynx, buccal, are oral cancer may occur . Sometimes lack of vitamins or other nutrients caused by the change of the oral mucosa can also induce the occurrence of cancer.
Some oral cancer will ask: “lump in my mouth, not pain, it should not matter right?” The risk of oral cancer will not hurt? Doctor’s answer may not be pain. Because of malignant tumors of the oral mucosa, early often do not violations of the nervous, so most will not pain; But when the tumor is too large nerve tissue of the tumor to the deep tissues of violating the nervous, the pain will be generated.
Outside in addition to pain, oral cancer tumor a little careless to come into contact with particularly vulnerable to bleeding. Because cancer cells are abnormal rapidly proliferating cells, the demand for nutrition than normal cells is much higher because of this very powerful, tumor angiogenesis, the face of external trauma the case of bleeding than normal cells is more evident. Compete for nutrients between the tumor cells, some distance from blood vessels for lost distant cells can not get enough nutrients and gangrene death of tissue necrosis in the oral cavity will lead to bad breath, the stench of such unpleasant and sometimes is one of the main reasons for patients at the doctor’s.
Oral ulceration is a common situation in daily life, general, oral ulcers; they do not continue to be subject to external trauma after appropriate treatment, usually heals within two to three weeks. If the same at the mouth ulcers, the wound healed over more than three weeks is not improved will have to pay attention to these difficult to heal ulcers or prominent ulcers most likely is the warning signs of oral cancer.
Neck mass is also a common symptom of oral cancer, some patients will be questioned: why oral cancer with a neck mass in a relationship? “According to current theory, early oral cancer, the cancer cells confined to the primary tumor region and, if not treated in time, the oral cancer cells will move with the flow of lymph, when transferred to the neck lymph nodes, it will form a hard texture and a fixed neck surrounding toothache incurable consequences soft tissue mass. One can imagine that when neck lump, the tumor in addition to primary oral position, also in cervical lymph nodes form the other malignant tissue rallying point not only increases the difficulty of treatment, the effects of treatment are relatively poor.
Early diagnosis, early treatment is often the only way to achieve the best effect. Oral cancer patients are 45-year-old male patient is often an important economic pillar in the home, oral cancer is not only the health of family members direct impact, but also washed away the family economy.
Therefore, maintain their own oral habits do not easily ignore. Discomfort teeth or dentures, some friction to the surrounding tissue, and should ask the dentist correction; normal diet, food and nutrition should be balanced; frequent mouth brush your teeth, maintain oral health, oral lumps of fat, peeling drop crumbs or color changes, more than two weeks without improvement, consult a doctor as soon as possible.
