The cancer occurs due to exposure to asbestos and is the most serious It is a silent and sudden disease that, like many cancers, takes a Time is the killer for mesothelioma, and if one waits on the signs, it may be too late. The first symptoms of mesothelioma include chest or abdominal pain, bloating and shortness of breath, depending on the location of the cancer .Mesothelioma a once rare type of cancer primarily caused by exposure to Mesothelioma Cancer A Slow and Silent Killer vomiting Significant change in bowel habits including sudden onset diarrhea or constipation.
1. What is mesothelioma
The lungs of the chest, heart, abdominal organs, etc. are wrapped in membranes such as the pleura, pericardium, peritoneum and so on. The surface of these membranes. It is “mesothelium” that is covered, and the tumor arising from this mesothelium is called mesothelioma. Therefore mesothelioma, its generation Pleural mesothelioma (80%) · Peritoneal mesothelioma (20%) · Pericardial mesothelioma (rare) · Testicular mesothelioma (rare), etc., depending on the position.
Mesothelioma may be malignant or benign, but in cases where it is generally described as mesothelioma, it means malignancy (It is all in this HP). Malignant mesothelioma is a rare tumor (its frequency is less than 1% compared to lung cancer). More than 80% of mesothelioma is thought to involve asbestos (asbestos), and it has become a very significant trend in recent years.
Mesothelioma occurs even at low exposure levels of asbestos, but roughly 40 years (at least 20 years later) have not elapsed since the initial exposure No, it does not develop. Therefore, even if the exposure amount is small such as neighboring exposure or home exposure, It means that the tumor may develop.
Symptoms are the most frequent breathlessness and chest pain, followed by cough, fever, etc. Malignant mesothelioma is localized in some cases, but it diffusely spreads widely along the pleura or peritoneum in general
to come. In diffuse malignant mesothelioma of the pleura, dyspnea and chest pain occur due to massive pleural effusion. Touch the chest wall lump In rare cases it will become to be. In peritoneal malignant mesothelioma, abdominal distension and abdominal pain due to ascitic fluid retention are many, and in women, it is necessary to differentiate it from ovarian cancer.
Malignant mesothelioma of the pleura is thickening of the pleura which spreads like piercing the entire lungs in chest X-ray photograph or chest CT, It is recognized as a stiffness, and it may accompany a large amount of pleural effusion. However, pleural dissemination such as lung cancer (Kyousai hazu: lung cancer is breast It may be difficult to distinguish it from a state in which it spreads and spreads across the membrane surface).
For mesothelioma that is localized and becomes massive, pleura It is necessary to differentiate it from the lung cancer directly beneath it. For other tests, a method is often used to pierce a needle into the chest and examine pleural effusion. Hyaluronic acid in the collected pleural effusion was 10. There is a possibility of mesothelioma if there are over 10,000 ng / ml. We also examined tumor cells in pleural effusion, biopsies under local anesthesia. Take a tumor on the pleural surface with a thoracoscope etc. to investigate them (histopathological examination).
In general, malignant pleural mesothelioma refers to a diffuse one, but malignant diffuse pleural mesothelioma is very prognostic. It is a bad illness. Treatment for this is surgical therapy, radiation therapy, chemotherapy (anticancer drug therapy) and symptomatic treatment I will do.
5. Stage (stage)
Malignant pleural mesothelioma can be divided into the following four stages depending on the progress of the disease. Staying in the thoracic cavity on one side of stage I.
Stage II chest wall · mediastinum (place where there is a part between right and left lungs, that is, heart, esophagus, large blood vessel, etc) · opposite pleural membraneWhat has advanced. Those involving chest cavity, peritoneal cavity or lymph node outside the thoracic cavity on both sides of III phase advanced.
Stage IV involving metastasis of hematogenous.
6. Treatment by stage (stage)
Surgical therapy may be done for stage I patients. All lesions, including the lungs, are delivered to the pleura, and optionally. Total curectomy is performed to remove the diaphragm and pericardium. However, even with such a big surgical therapy, Sometimes, symptomatic surgical therapy that removes the widest area of the pleura and prevents pleural effusion is another treatment (radiation). It may be done in combination with therapy or chemotherapy. In addition, when pleural effusion is stored in large quantities and it is difficult to breathe. In order to eject pleural effusion outside the body and ease breathing, we will take measures to insert the tube in the chest.
Radiation therapy and chemotherapy are performed if it is difficult to remove all lesions by surgical therapy at stages II and above.
Line therapy is a therapy that irradiates the area where radiation is present in the area where the tumor exists and kills the tumor cells and reduces the tumor. Also, chemotherapy.
The method is a treatment method of administering anticancer drugs to tumor cells, usually by intravenous drip medication to the whole body.
