Mesothelioma cancer is a type of cancer that attacks the lungs and chest cavity. Also known as the asbestos lung cancer, deadly form of mésothéliales tumors where cancer cells form a protective coating on the lungs, the heart and the abdominal organs. It is a type of lung cancer, many years for the development and manufacture of symptoms. Around 3000 cases per year (mostly men who are older than 40 years). It is estimated that the number is estimated at about 300000 cases in 2030.
Types of cancer, mesothelioma asbestos
Épithéliales mesothelioma is a rare form of cancer and fatal effects on the mucosa of the chest cavity, heart, lungs and abdominal cavity. There are three forms of epithelial mesothelioma: the most common Pleural Mesothelioma is the second most common, peritoneal mesothelioma (which only a quarter of cases), and the shape that rarely, pericardial mesothelioma.
Mesothelioma pleural effusion, the type of the disease means that the pleura, a thin membrane between the lungs and chest cavity. The pleura lubricated, a surface so that the lungs do not scrub and chafe against the chest walls. There are two types of pleural mesothelioma, the first is “widespread and vicious.” This guy is oncology, and is usually fatal in the year after diagnosis. The second type is “benign and localized” and is usually not his life in danger. It is normally removed by surgery.
Lining of lung cancer, is not to be confused with lung cancer. In the seal of lung cancer, the field of the body, the so-called mésothélium, a thin membrane, based on a variety of internal organs of the body. The mésothélium the lung, the pleura. Lining of lung cancer, is also sometimes called mesothelioma after the region where it occurs.
This thin membrane is composed of two layers, - around the organ and another form, which is on the outer side of the bag to the first layer. Between the layers of the mésothélium is a fluid, one of the vital organs to glide easily against objects that are in contact with them.
City pleural mesothelioma is not always by asbestos exposure. If, however, it has focused on other parts of the body, such as the lymph nodes, lungs, chest or abdominal wall bodies, it is as vicious and is often the result of exposure to asbestos.
Mesothelioma peritoneal appears as a tumour in the peritoneum membrane of the abdomen. This type of mesothelioma is a very rare, with fewer than a quarter of all known cases of the disease. There is no effective treatment for this disease, and most patients live on less than one year after diagnosis.
Mésentère cancer is a cancer peritonealer (mesothelioma). This cancer is concerned mainly with the various bodies peritoneum, which is on the wall of the abdominal cavity, (ie mésogastre for the stomach, mesojejunum for jéjunum). Mésentère abdominal peritoneal cancer contains all extensions. Rare tumors originate in the Mesenteriums, even if it is a common way of the spread Mesothelioms through the abdominal cavity.
Péricardique mesothelioma is the rarest form of mesothelioma, the membrane around the heart (the so-called pericardium, or pericardial bags). In this disease, massive and Erguß (liquid) to develop the pericardium. All martyrdom is not solely related to mesothelioma.
The causes
The Mesothelioma is a cancer resulting from exposure to asbestos fibres or dust. The workers in the asbestos industry are the targets of choice for this deadly disease. Asbestos fibers in the body, either through breathing in the small asbestos fibers or swallowing disorders. The healthy fibers cause cancer cells to mutate. Since the organization is unable to dispel the fibers inspire the lung (asbestosis). This disease is and malicious. Exposure to asbestos is thought to the origin of some 75% of all cases of lung cancer fodder.
Symptoms
It is very difficult mesothelioma, a cancer at an early stage. The first symptoms tend generally, and even in some cases non-existent, and it can take up to 15 to 50 years after exposure to grow. The first symptom is often constant pain in breast, followed by coughing, the injuries of the lungs and shortness of breath. Patients who peritoneal mesothelioma (a rare form of mesothelioma) usually have the experience of abdominal pain, loss of appetite, nausea and abdominal swelling, which is often the symptoms of pleural mesothelioma. You can also create new bowel obstruction or obstruction of the airways.
Diagnostic steps and Mesothelioma
There are three systems of production used to determine the treatment for mesothelioma: Butchart system, TNM system, and the Brigham system
Butchart staging system
The Butchart System is the oldest and most common. This system focuses on determining the size of the primary tumor mass and mesothelioma in four steps.
Step I of the Butchart System consists in the presence of mesothelioma in the wall on the right or left side of the lungs and can also mean that the diaphragm on the same page. Phase II involves the development of mesothelioma in the wall of the breast, esophagus, lung or otherwise coating on both sides. It is also the lymph nodes in the chest. The beginning of the third phase begins when the mesothelioma through the diaphragm into the mucosa of the stomach cavity or peritoneum. At that time, cancer can also count on the lymph nodes go beyond the breast. The doctors of the identification phase IV, the last step if the evidence of the spread of cancer to other organs (metastasis), confirmed.
TNM system, which is in phase I of the TNM system includes the coating of the right or left of the lung, pericardium, or diaphragm on the same page. At that time, the lymph nodes are not involved. Phase II begins when the mesothelioma extends from the wall in the lung, on the one hand to a ganglion on the same page. At this stage the cancer is in the lung, pericardium, or diaphragm on the same page. Phase III will begin when the mesothelioma in the chest wall, muscle, on the coast of the heart, esophagus, or other organs in the chest on the same side as the primary tumor. In the final phase, Phase IV, the mesothelioma travelled to the lymph nodes in the chest on the front of the tumour elementary school, in the lungs compared to the primary tumor, or directly to the organs of the abdominal cavity or neck. Metastasis is the end result of this step.
Brigham system
The system determines the Brigham resectability (the ability to surgically remove), mesothelioma mass. In Phase I of the tumor is resectable, while the lymph nodes are not affected. In Phase II, the tumor still significant, but the mesothelioma affects the lymph nodes. In Phase III is the non-tumour. He went through the membrane or the peritoneum. Phase III can be used with or without the participation and the lymph in the wall prolonged chest and heart function. Stade IV occurs when doctors are discovering the metastatic disease, the remote facilities.
After the doctors to identify the scene of a malignant mesothelioma of the patient, the patient and the doctor is the different ways of treatment. Mesothelioma programs for the treatment depends on many factors, including the stage of cancer, the location of the cancer, the spread of the cancer mesothelioma, the characteristics of the cancer cells under a microscope and the age of patients and concerns.
