Main Cancer: Causes, Symptoms and Treatment

There are different types of cancer crops in the head and neck that can spread in the throat, salivary glands, tongue, pharynx, mouth, sinus and other sinuses, and their survival without treatment for these tumors can spread to the lymph nodes, bones and other tissues in the rest of the body, and the head and neck are usually after exposure to Carcinogens, it is the exposure to Carcinogens. Since the carcinogine is the then, it is exposed to Karcinogens, as the carcinogine is the then. to IT Cancer causes. Types of head cancer, neck, head cancer and neck are classified as follows according to the most important source of the crop: the tumors in the upper airway and the esophagus area of ​​cancer crops in these areas include lips, mouth, throat, pharynx and vocal tendons. The crops of these organs are the most common of all types of head and neck cancer, and the source of these crops is often the epithelial cells. These distinctive cells are devoted to head and neck tissue and are mainly concentrated there. This type of cancer is not classified as a learning cancer, although the source is epithelial cells, and this cancer is often diagnosed with people older than 45 years, and the chances of men being infection with this type of cancer infection are more than four times the appearance of women. More than 90% of this type of crop is related to smoking, alcohol consumption increases the risk of cancer crops in these organs, especially if consumption is excessive and chronic. Saliva tumors occur less frequently, and their percentage among all types of cancer in the head and neck is relatively low. There are different types of salivary glands, and the intensity of the disease and the spread of the crop varies. Radiation exposure increases the risk of head and neck cancer in the salivary glands, and smoking also plays an important role in cancer rise in these tissues. Crops at the back of the throat and at the tip of the meeting between the pharynx and nose caves. This type of cancer, and unlike other head and neck cancer, has nothing to do with smoking and excessive alcohol consumption. This distinctive material is more sensitive to chemotherapy and radiotherapy than the rest of the cancers growing in the head and neck. The main cause of these crops has not yet been found, but in the areas where cancer of this type is spread, there is an assumption that this tumor is caused by the viral infection, which is responsible for causing kissual mononucleosis, which is the Epstein -Barr virus -EBV. Sinus and nasal system crops that most crops are in these tissues of the type of paving, and the type of cancer is rarely cancer. In most cases, these crops are diagnosed relatively late because the nasal cavity contains enough space to grow the tumor without causing special symptoms.
