Mesothelioma cancer is a type of cancer that attacks the lungs and chest. Also asbestos lung cancer is known, it is deadly tumors that form in which mesothelial cancer cells, a protective lining of the lungs, heart and abdominal organs. It is a type of lung cancer that takes many years to develop and cause symptoms. Approximately 3,000 cases per year (mostly men aged over 40) are reported. It is estimated that number will grow to about 300,000 cases before 2030th
Types of mesothelioma asbestos cancer
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, the second most common, peritoneal mesothelioma (accounting for only one quarter of cases), and the rarest form, pericardial effusion> Mesothelioma.
Pleural mesothelioma, the most common form of this disease requires the pleura, a thin membrane between the lungs and the 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 "diffuse and malignant. This guy has cancer and is usually fatal within one year after diagnosis. The second type is localized 'andbenign and is not life in general. It can be generally removed by surgery.
Lung cancer food is not be confused with lung cancer. Cancer in the lung lining 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 the pleura. Lung cancer is sometimes called mesothelioma feed after the area in which it occurs.
This thin membrane is composed of twoLayers - one that surrounds the body, and another, an outer bag to the first layer is formed. Between the layers of the mesothelium is a liquid, vital organs can easily against objects that slide coming into contact with them, too.
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 is considered malicious and moreoften the result of asbestos exposure.
Peritoneal mesothelioma appears as a tumor in the abdominal 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.
Mesentery cancer is to compare peritoneal cancer (mesothelioma). This cancerconcerns in particular sections of the peritoneum that put different bodies on the wall of the abdominal cavity (ie mesogastrium for the stomach, mesojejunum) for the jejunum. Mesentery cancer includes all the abdominal peritoneal extensions. Tumors rarely originate in the true mesentery, but it is a frequent route for the spread of mesothelioma through the abdominal cavity.
Pericardial mesothelioma is the rarest form of mesothelioma,Effects on the membrane around the heart (the so-called pericardium, or pericardial). In this disease develop into solid masses, and effusion (fluid) around the pericardium. Not all emissions are to be strictly related mesothelioma.
The causes
Mesothelioma cancer is caused by exposure to asbestos fibers or dust. Workers in the asbestos industry are preferred targets for the attraction of this deadly disease. Asbestos fibers enter the body either by breathing in thetiny asbestos fibers or be swallowed. The fibers cause healthy cells to mutate into cancer. Since the body is unable to dispel these fibers, which are inflamed lungs (asbestosis). This condition is deteriorating and will eventually be malignant. Asbestos is thought to approximately 75% of all cases of lung cancer, forage to be responsible.
Symptoms
Mesothelioma is a very difficult to detect cancer at early stages. The first symptoms are usually generic andeven in some cases does not exist, and it can be as much as 15 to 50 years to develop after exposure. The first symptom is often constant pain in the chest, coughing, lung damage and shortness of breath followed. Patients who have peritoneal mesothelioma (a less common form of mesothelioma), usually experience abdominal pain, anorexia, nausea, and abdominal swelling, often in addition to the symptoms of pleural mesothelioma. You can also develop intestinal obstructionobstruction or other breathing.
Events and diagnosis of mesothelioma
There determining three staging systems for treatment of mesothelioma: Butchart system, TNM system and the Brigham System
Butchart staging system
The Butchart System is the oldest and the most commonly used. This system focuses on determining the extent of the primary tumor and mesothelioma is divided into four phases.
StageI of the Butchart System consists of the presence of mesothelioma in the lining of the right or left lung and may involve the diaphragm on the same page. Phase II includes the progression of mesothelioma in the chest wall, esophagus, lung, or food for the trouble site. It can also lymph nodes in the chest. The beginning of the third stage begins when it exceeds the mesothelioma of the diaphragm into the lining of the abdominal cavity or peritoneum. At this stage the cancer ismay also extend to the lymph nodes in the chest. Doctors identify Stage IV, in the final stage, when evidence is confirmed) for the spread of cancer to other organs (metastasis.
TNM system
Phase I of the TNM system includes the lining of the right or left lung, pericardium, or diaphragm on the same page. At this stage, lymph nodes are not involved. Phase II begins when mesothelioma of the lining of the lungs, spreads on one side to a lymph nodeNodes on the same page. At this stage of cancer can also spread to the lung, pericardium, or diaphragm on the same page. Stage III begins when mesothelioma in the chest wall, muscle, ribs, heart, esophagus or other organs in the chest on the same side as the primary tumor is present. In the final stage, Stage IV, the mesothelioma has traveled to the lymph nodes in the chest on the opposite side of the primary tumor in the lung compared to the primary tumor, or directly intothe organs in the abdominal cavity or neck. Metastasis is the final result at that stage.
Brigham System
The Brigham system determines the resectability (the ability to surgically remove) the mesothelioma mass. In Phase I of resectable tumor, while leaving the lymph nodes affected. In Phase II, the tumor remains respectable, but the mesothelioma affects the lymph nodes. In Phase III, the tumor is inoperable. It has penetrated through theDiaphragm or peritoneum. Stage III can occur with or without involvement of the lymph, and extends into the chest wall and heart. Stage IV occurs when doctors discover metastases with distant organs.
After doctors look at the stage of malignant mesothelioma, a patient, the patient and physician to identify the various treatment options available. Mesothelioma treatment programs are dependent on many factors, including the stage of the cancer, the location of theCancer, the spread of mesothelioma cancer, the properties of cancer cells under the microscope and the patient's age and concerns.
