Mesothelioma cancer is a type of cancer that attacks the lungs and chest cavity. Also known as asbestos lung cancer, and forms a deadly cancer, where malignant mesothelial cells as a form of protective lining of the lungs, heart and abdominal organs. This is a type of lung cancer that takes many years to develop and produce symptoms. Roughly 3,000 cases per year (mostly men over 40 years) have been reported. It is estimated that about 300,000 more women in cases before the 2030th
Types of Asbestos Cancer Mesothelioma
Epithelial mesothelioma is a rare and deadly form of cancer affecting the membranes lining the chest cavity, heart, lungs, and abdomen. There are three forms of epithelial mesothelioma: pleural mesothelioma, the most common, is the second most common, peritoneal mesothelioma (accounting for only a quarter of the cases), and the rarest form, pericardial mesothelioma.
Pleural mesothelioma, the disease most commonly involves the pleura, a thin membrane located between the lungs and chest cavity. Provides a lubricated surface of the pleura, so the lungs do not rub and chafe against the chest wall. There are two types of pleural mesothelioma is the first that “the fugitive, and malicious.” This type of cancer and is usually fatal within a year of diagnosis. The second type is the “local and benign” and are usually not life threatening. It is usually removed through surgery.
Lung Lining Cancer is not to be confused with lung cancer. The lining of lung cancer, carried out in the area of the body in the mesothelium, a thin membrane that covers many internal organs of the body. The mesothelium of the lungs called the pleura. Lining Mesothelioma Lung cancer is known as an area where there.
This thin membrane is composed of two layers – which surrounds the organ and another that forms an outer shell around the first layer. Between the layers of the mesothelium is a liquid, allowing the vital organs to glide easily against objects that come into contact with them.
Localized pleural mesothelioma is not always caused by asbestos exposure. If, however, has spread to other parts of the body, such as the lymph nodes, lungs, chest wall, or abdominal organs, it is malicious and more often than not the exposure to asbestos.
Peritoneal mesothelioma is a tumor of the peritoneum membrane of the abdomen. This type of mesothelioma is very rare, representing less than one-quarter of all known disease. There is no effective treatment for this condition, and most people live on less than a year after diagnosis.
Mesentery can be compared to cancer, peritoneal cancer (mesothelioma). This cancer mainly affects the phases of the peritoneum that attach to the wall of various organs in the abdominal cavity (ie mesogastrium the stomach, jejunum mesojejunum). Mesentery cancer includes all abdominal peritoneal extensions. Tumors rarely originate in the mesentery of the actual, though often the spread of mesothelioma through the intraperitoneal route.
Pericardial mesothelioma is the rarest form of mesothelioma affects the membrane around the heart (called the pericardium or pericardial sac). In this disease, solid masses and fluid (liquid) to develop the pericardium. Not all the fluid is strictly linked to mesothelioma.
The reasons
Mesothelioma cancer is caused by exposure to asbestos fibers or dust. Workers in the asbestos industry’s primary target is to attract the deadly disease. Asbestos fibers enter the body, or a little breathing or swallowing asbestos fibers in them. Cause the fibers in healthy cells mutate into cancer. Since the body is unable to remove these fibers in the inflamed lung (asbestosis). This condition is deteriorating and eventually become malignant. Exposure to asbestos is thought to be responsible for approximately 75% of all cases of lung cancer in the lining.
Symptoms
Mesothelioma is a very difficult to detect the cancer early. Early symptoms are usually general and non-existent in some cases and it can take up to 15 to 50 years after exposure to develop. The first symptom is usually a constant pain in the chest by coughing, lung damage, and shortness of breath. Patients who have peritoneal mesothelioma (mesothelioma of the less common form) usually experience abdominal pain, anorexia, nausea, and abdominal distension, too often the symptoms of pleural mesothelioma. They may also develop bowel obstruction or other breathing barrier.
Stages and Diagnosis of Mesothelioma
Three temporary system used to determine treatment of mesothelioma: Butchart system, TNM system and the Brigham System
Butchart Staging System
The Butchart System is the oldest and the most common system. This system focuses on determining the extent of the primary tumor mass and divides mesothelioma in four stages.
I section of the Butchart System is the presence of mesothelioma in the lining of the right or left lung and also involve the diaphragm on the same side. Stage II involves the progression of mesothelioma in the chest wall, esophagus or lung lining on bother sides. There may also be nodes in the chest. The initial phase III begins when mesothelioma is superior to the membrane lining the abdominal cavity or peritoneum. At this stage, the cancer may also affect the lymph nodes beyond the chest. Doctors identify Stage IV, the last stage, when evidence of the spread of cancer to other organs (metastasis) confirmed this.
TNM system
I TNM stage of the scheme involves the lining of the right or left lung, pericardium, or diaphragm on the same page. At this stage, no lymph nodes involved. Stage II begins when mesothelioma spreads to the lining of the lung on one side of a lymph node on the same page. At this stage the cancer has spread to the lungs, pericardium, or diaphragm on the same page. Stage III begins when mesothelioma is present in the chest wall, muscles, ribs, heart, esophagus and other organs in the chest on the same side as the primary tumor. In the final stage, Stage IV Mesothelioma traveled to the lymph nodes in the chest on the side opposite the primary tumor of the lung, compared to the primary tumor, or directly to the organs in the abdominal cavity or neck. Metastasis to the final result in this section.
Brigham System
The Brigham system determines resectability (the ability to surgically remove) the mesothelioma mass. I rate of inoperable cancer of the lymph nodes are not affected. In Stage II the tumor is respectable, but a mesothelioma affects the lymph nodes. In Stage III the tumor becomes inoperable. It penetrated through the diaphragm, or peritoneum. Stage III can occur with or without lymph node involvement and extends to the chest wall and heart. Stage IV occurs when doctors discovered metastatic disease, which is distant organs.
Once the doctors determine the stage of a patient’s malignant mesothelioma, the patient and the doctor examines the different treatment options available. Mesothelioma treatment programs are dependent on many factors, including the stage of the cancer, the location of the cancer, mesothelioma cancer spread, the characteristics of the cancer cells under a microscope, and the patient’s age and concerns.
