Mesothelioma

Most of malignant mesothelioma is due to long-term asbestos work in an environment of incoming asbestos or asbestos exposure to live in the family environment caused. In rare cases, exposure to asbestos or even one month may also lead to mesothelioma.
National Association of mesothelioma cancer is the definition: Mesothelioma is a rare find in the mesothelial cells of malignant cancer. Most of the patients suffering from mesothelioma due to asbestos floating work environment, thus arising from the inhalation of asbestos particles.

Mesothelioma often in the lung or abdominal membrane. Although the disease usually takes several decades in the post-exposure to asbestos form, but once there mesothelioma, it will spread very quickly and deteriorate.

Because mesothelioma and other symptoms of the disease is less Xiang Xiang, coupled with the onset of the disease for a long time interval, mesothelioma patients generally have to wait until after onset of disease symptoms can be felt. .


What is mesothelioma »


Pleural mesothelioma is pleural primary tumor, there are limitations of (mostly benign) and diffuse (all malignant) points. Which diffuse malignant mesothelioma to the chest tumor one of the worst prognosis.
The first symptoms of chest pain, coughing and shortness of breath was the most common. Have a fever, sweating or joint pain mainly v. symptoms. About half of patients over a large number of pleural effusion with severe shortness of breath. No large pleural effusion, chest pain often even more, common weight loss. Ordinary X-ray found that pleural effusion, and lung tumor was wrapped, and so on, have advanced cases can cause the heart pericardium exudate video to expand and soft tissue damage, such as video and ribs.

For suspicious of malignant pleural mesothelioma patients, CT check the most useful. Hydrothorax cytology also contribute to the diagnosis. Routine laboratory tests, some patients may have more platelets, serum carcinoembryonic antigen (CEA), such as elevated. For routine examination not clear diagnosis can be done pleural thoracoscopic biopsy. General most patients can have access diagnosis.

The treatment of malignant pleural mesothelioma, is still no effective cure methods. Treatment, a surgical treatment, chemotherapy and radiation treatment, the tumor is generally believed that the relative limitations of the stage I patients, so radical that the pleural pneumonectomy. For Ⅱ, Ⅲ, Ⅳ of patients, radical surgery has no meaning, only the purposes of palliative surgery

Most of morbidity in patients between the ages of 40-70, men more than women.

Mesothelioma causes


Is the main cause of mesothelioma patients to asbestos exposure. Approximately 70 - 80% of the diagnosis of mesothelioma patients exposed to asbestos at work in history. However, there are some mesothelioma patients do not have any records of contact with asbestos.
Asbestos fibers can be a lot to be dispersed into the air and minerals. Asbestos was widely used in many industrial products, including cement, gates lining, roof-tile, textiles and insulation materials.

If tiny asbestos particles floating in the air, particularly in the manufacturing process, they will be inhaled and cause serious health problems.

In addition to mesothelioma, the asbestos exposure increased lung cancer, asbestos calmly disease (noncancerous, chronic lung disease) risk, and other cancers, such as jets and kidney cancer.

The combination of smoking and asbestos greatly increased air access with the risk of disease.

Mesothelioma exposure


Asbestos manufacturers as early as the 1970s ago to understand exposure to asbestos could lead to the risk of mesothelioma cancer, but they will this information as trade secrets to strictly control. The first exposure to asbestos on the reports in the mid-1960s. Even today, asbestos manufacturers are still long as possible hide the fact that the asbestos risk.

People long-term exposure to asbestos in the environment caused by inhaling asbestos mesothelioma of the risk to increase dramatically, but recent study found that even very short-term exposure to asbestos can also lead to the disease. In general, mesothelioma need 20 to 40 years before symptoms show, people usually aged between 50 to 70 were diagnosed with this disease.

Although the reported rate in the past 20 years has increased, mesothelioma is still a relatively rare cancer. The United States each year there are about 2,000 new mesothelioma was diagnosed cases.
