Carcinoma of the salivary gland are curable
Despite many years of study on cancer, scientists are not too well understood reasons for which a normal cell begins to divide uncontrollably, affecting the surrounding tissue, forming a secondary tumor foci in the near and distant organs. It also remains a mystery why some education does not have a tendency to lose tissue, with the sound and others don't.
In trying to find answers to these important questions, scientists continue to study cancer. One of them is a carcinoma of the salivary gland.
Neoplasms of the oral cavity
Tumors that are capable of hitting slizistoi mouth, appear at the location of the salivary glands. They are under the tongue, on the side of the mouth in front of the ear and under the lower jaw, respectively, in these places are different types of tumors. Tumors can be divided into several types:
1.1. Monomorphic adenoma.
1.2. Adeno lymphoma.
2.1. Pleomorphic adenoma that fits the definition of squamous cell carcinoma– histological tumor, the cells of which are practically the same, since due to the degeneration have lost the ability to specialization. This disease is common in the mouth of the rug most often occurs in the parotid gland.
2.2. Mucoepidermoid tumor, fits the definition of undifferentiated cancer is an aggressive tumor with a low specialization of cells, which is very aggressively penetrates tissues, characterized by rapid metastasis and can be located anywhere in the oral cavity.
2.3. Adenokistoznaya carcinoma of the salivary gland, cylindricity cancer, undifferentiated cancers, the slow-growth and aggressive-invasive character, obladayuschaya a tendency to relapse. Since this disease is characterized by active formation of metastasis, penetrating into the closest lymph nodes, it bastard forms a secondary tumor foci in the lungs.
2.4. Carcinoma of the salivary glands, also related to cylindrocladium cancer is localized, in most cases, the minor salivary glands of the palate. It has a wide prevalence and low ability of cells to specialization. The tumor secretes the ability to rapid penetration, and is also characterized by the spread of the metastasis of blood and lymphatic fluid in lungs and bones. In comparison with this type of cancer, carcinoma of the parotid salivary glands affects the body much less frequently.
In the early stages of cancer of the salivary gland occurs without any obvious symptoms. Then there appear such signs of illness:
1. Excessive salivation or constant dryness of the mouth.
2. Swollen glands, bulging to the outside or inside of the oral cavity, which gradually increases.
4. Periodic numbness of the face, where the tumor.
There is no accurate data that can help to formulate a conclusion about the reasons of developing this disease. For example, it was found that this type of tumor is not inherited. Suggested that the emergence of this disease due to a specific gene mutation.
However, the experts were able to isolate the factors contributing to the development Atagi disease:
- High doses of ionizing radiation that could be received as a result of the treatment beams tumors of the head.
- The influence of oncogenic viruses.
- Traumas and inflammatory processes in the mouth that are chronic in nature.
Diagnosis and treatment of disease
Identify the disease help laboratory tests conducted by the doctorbecame suspicious when examining a patient. The patient is prescribed ultrasound of the neck, Magnetic resonance therapy, as well as the test sample of cells taken from mucosal. Efficiency of treatment directly depends on which stage the disease is diagnosed. Treatments also depend on the condition of the tumor.
Upon confirmation of the diagnosis, the patient in the early stages can offer to excise the tumor surgically. The alternative is radiation therapy, which is possible if the tumor size does not allow him to cut, and when the patient's refusal from surgical intervention in fear of damaging the facial nerve and to disfigure the face. After surgery and treatment rays, the patient can be chemotherapy.
