Cancer Mesothelioma is a type of cancer that attacks the lungs and chest. Although lung cancer asbestos is known, is the deadly form of cancer in which cells of mesothelial cancer, a protective lining of the lungs, heart and abdominal organs. This is a type of lung cancer, which require many years to develop and cause symptoms. About 3,000 cases per year (mostly men aged over 40) are reported. It is estimated that the number will growabout 300,000 cases before 2030.

Types of asbestos cancer mesothelioma

Epithelial mesothelioma is a rare and deadly form of cancer, the lining of the chest cavity, heart, lungs and abdomen. There are three forms of epithelial mesothelioma: The most common is pleural mesothelioma, mesothelioma second most common, peritoneal (with only one quarter of cases), payment and the rarest form, pericardialMesothelioma.

Pleural mesothelioma, the most common form of this disease requires the pleura, a thin membrane between the lungs and rib cage removed. The pleura is a lubricated surface so that the lungs do not rub and rub against the chest wall. There are two types of pleural mesothelioma being the first "widespread and malignant. This guy has cancer and is usually fatal within one year after diagnosis. The second type is located 'and benign' and isusually not life-threatening. Can generally be removed surgically.

Food lung cancer should not be confused with lung cancer. Cancer of the lining of the lung is the effect of area of the body called the mesothelium, a thin membrane that covers many of the internal organs of the body. The mesothelium of the lungs is called pleura. Lung cancer is sometimes called mesothelioma after the feed zone whereoccurs.

This thin membrane is composed of two layers – one that surrounds the body and another, an outer bag is the first layer. Between the layers of the mesothelium is a liquid, vital organs can easily against objects that flow coming into contact with them.

Localized pleural mesothelioma is not always caused by asbestos. However, if it has spread to other parts of the body, such as the lymph nodes, lungs, chest wall, or abdominal organs, then it was considered malignant, and is often the result of exposure to asbestos.

Peritoneal mesothelioma appears as an abdominal tumor in the membrane of the abdomen. This type of mesothelioma is very rare, representing less than one quarter of all known cases of the disease. There is no effective treatment for this disease, and most patients live less than a year after diagnosis.

Peritoneal dialysis and cancer compared MesenteryCancer (mesothelioma). This type of cancer prevalent among sections of the peritoneum that put different bodies on the wall of the abdominal cavity (mesogastrium ie for stomach, mesojejunum) for fasting. Mesentery Cancer includes all extensions abdominal peritoneum. Tumors rarely originate in the mesentery true, but is a frequent route for the spread of mesothelioma through the abdominal cavity.

Pericardial mesothelioma is therarest form of mesothelioma, the membrane around the heart (the so-called pericardium, or pericardial). In this disease develop into solid masses, and slip (liquid) throughout the pericardium. Not all issues should be closely related mesothelioma.

Causes

Mesothelioma cancer is caused by exposure to asbestos fibers or dust. The asbestos industry workers are preferred targets for the attraction of this deadly disease. Asbestos fibers enter the body, eitherbe from breathing asbestos fibers small or ingestion. The fibers induce healthy cells to mutate into cancer. Since the body is able to dispel these fibers, which are inflamed lungs (asbestosis). This condition is deteriorating and will eventually be malicious. Asbestos is thought about 75% of all cases of lung cancer, forage to be responsible.

Symptoms

Mesothelioma is very difficult to detect cancer in early stages.The first symptoms tend to be generic and available in some cases not, and can be up to 15 to 50 years to develop after exposure. The first symptom is often constant chest pain, coughing, shortness of breath and lung damage later. Patients who have peritoneal mesothelioma (a less common form of mesothelioma), usually experience abdominal pain, anorexia, nausea, bloating and, often, in addition to symptoms of pleural mesothelioma. Can also develop bowel obstruction or other respiratory obstruction.

Events and diagnosis of mesothelioma

We determine three staging systems for treatment of mesothelioma: Butchart System, the TNM system and the system of Brigham

Butchart staging system

The Butchart System is the oldest and most commonly used. This system focuses on determining the extent of primary cancer and mesothelioma is divided into four phases.

> Phase I of the Butchart System is the presence of mesothelioma in the lining of the lung left or right and can involve the diaphragm on the same page. Phase II includes the progression of mesothelioma of the chest wall, esophagus, lung or coating on the sides. You can also take care lymph nodes in the chest. The beginning of the third phase begins when you exceed the mesothelioma of the diaphragm in the lining of the abdominal cavity or peritoneum. This Stage of cancer may also extend to the lymph nodes in the chest. Doctors identify Stage IV, the final stage, when the test is confirmed) for the spread of cancer to other organs (metastasis.

TNM

Phase I of the TNM system provides for the right or left lung lining, the pericardium, or diaphragm on the same page. At this stage, the lymph nodes are not involved.> Phase II begins when mesothelioma of the lining of the lung, extends on one side of a lymph node on the same page. At this stage the cancer is lung, pericardium, diaphragm or distributed on the same page. Phase III begins when mesothelioma of the chest wall, muscles, ribs, heart, esophagus or other organs in the chest on the same side, as the presence of the primary tumor. In the last phase, Phase IV, has mesotheliomatraveled to the lymph nodes in the chest on the opposite side of the primary tumor in the lung compared to primary tumor or directly into organs in the abdominal cavity or neck. Metastasis is the final result, at that stage.

Brigham System

The system of Brigham determines resectability (the ability to surgically remove) the mass of mesothelioma. In the first phase of a resectable tumor, leaving the affected lymph nodes. In phase II,the tumor remains respectable but mesothelioma affects the lymph nodes. In phase III, the tumor is inoperable. It has penetrated through the diaphragm or peritoneum. Phase III can occur with or without the involvement of lymph, and extends into the chest wall and heart. Stage IV occurs when doctors discover metastases distant organs.

Once doctors know the stage of malignant mesothelioma, a patient, the patient and doctorconsider the various treatment options available. Mesothelioma treatment programs depend on many factors, including the stage of cancer-related, the location of the tumor, the spread of cancer mesothelioma, the properties of cancer cells under the microscope and the patient's age and concerns.
