MESOTHELIOMA

The cancer of mesothelioma is a type of cancer which attacks the lungs and the cavity of trunk. Also known as a cancer of asbestos lung, it forms the tumours mortals where the cancer cells mesothelial form a protective lining above the lungs, the heart, and the abdominal bodies. It is a type of cancer of lung which takes many years to develop and produce symptoms. Roughly 3.000 cases per annum (most of the time of the men above the age of 40) are reported. It is estimated it that the number will become approximately 300.000 cases before 2030.

Types of asbestos Cancer of mesothelioma

The epithelial mesothelioma is a rare form and mortal of cancer affecting the lining of membrane of the cavity of trunk, the heart, the lungs, and the abdominal cavity. There are three forms of epithelial mesothelioma: most common is pleural mesothelioma, the second common mesothelioma and p�riton�al (explaining only one quarter of the cases), and the rarest form, pericardial mesothelioma.

The pleural mesothelioma, the most common type of this disease implies the pl�vre, a thin membrane plac between the lungs and the cavity of trunk. The pl�vre provide a lubricated surface so that the lungs do not rub and do not overheat against the thoracic walls. There are two types of pleural mesothelioma first being �diffuse and malignant �. This type is cancerous and is generally mortal in one year of diagnosis. The second type is �localised and benign � and is generally to threaten without life. It can usually be removed by the surgery.

The cancer of lining of lung should not be confused with the cancer of lung. In the cancer of lining of lung, the sector carried out of the body is called the mesothelium, a thin membrane which covers several of the internal bodies of the body. The mesothelium of the lungs is called the pl�vre. The cancer of lining of lung is called also sometimes the mesothelioma after the sector in which it occurs.

This thin membrane is made up of two layers - one which surround the body and another which forms a bag external around the first layer. Between the layers of mesothelium is a fluid which allows the bodies essential to slip easily against the objects which contact them.

The pleural mesothelioma localised is not always caused by asbestos exposure. However, if it deviated with other parts of the body, for example the lymphatic ganglia, the lungs, the thoracic wall, or the abdominal bodies, then is considered to him malignant and is generally the result of the asbestos exposure.

The mesothelioma p�riton�al seems tumour in the membrane of peritoneum of the abdomen. This type of mesothelioma is very rare, comprising less than one quarter of all the known cases of the disease. There is no effective cure for this condition, and the majority of the patients live less than one year after diagnosis.

The Cancer of Mesentery is compared with cancer p�riton�al (mesothelioma). This cancer affects mainly the sections of the peritoneum which attach various bodies to the wall of the abdominal cavity, (C. - with-D. mesogastrium for the stomach, mesojejunum for the jejunum). The cancer of Mesentery includes all the abdominal p�riton�aux prolongations. The tumours seldom come from the real mesentery, although it is a frequent route for the diffusion of the mesothelioma by the abdominal cavity.

The pericardial mesothelioma is the rarest form of mesothelioma, affecting the membrane around the heart (called the pericardium or the pericardial bag). In this disease, the full masses and overflowing (fluid) develop around the pericardium. Not all overflowings are strictly related to the mesothelioma.

Causes

The cancer of mesothelioma is caused by exposure to fibres or the asbestos dust. The workmen in the asbestos industry are the main targets to attract this fatal disease. The asbestos fibres enter the body, by breathing in tiny asbestos fibres or by swallowing them. The fibres make undergo a change the healthy cells in cancer. Since the body cannot dissipate these fibres, the lungs become ignited (asbestose). This condition worsens and becomes thereafter malignant. The asbestos exposure is probably responsible roughly for 75% of all the cases of cancer of lining of lung.

Symptoms

The mesothelioma is a cancer very difficult to detect with the parts. The symptoms early tend to being generic and even non-existent in certain cases, and it can take not less than 15 to 50 years after exposure to develop. The primary symptom is often pain of trunk constant, followed cough, damage of lung, and brevity of the breath. Patients who generally have the abdominal pain of an experiment p�riton�ale of the mesothelioma (a less common form of mesothelioma), the loss of appetite, nausea, and abdominal swelling, often in addition to the symptoms of the pleural mesothelioma. They can also develop the obstruction of entrails or promote the obstruction of breathing.

Stages and diagnosis of the mesothelioma

There are three systems of presentation employed to determine the treatment for the mesothelioma: System of Butchart, system of TNM, and the system of Brigham

System of scaffolding of Butchart

The system of Butchart is the oldest system and most common. This system concentrates at the time determining the extent of the primary mass of tumour and divides the mesothelioma into four stages.

Stage I of the system of Butchart includes/understands the presence of the mesothelioma in the lining of the right or left lung and can also imply the diaphragm on the same side. Stage II includes the progression of the mesothelioma in the thoracic wall, the oesophagus, or the lining of lung on the sides of trouble. There can also be the lymphatic ganglia in the trunk. The beginning of stage III starts when the mesothelioma exceeds the diaphragm in the lining of the abdominal cavity or the peritoneum. In this stage cancer can also affect the lymphatic ganglia being prolonged beyond those in the trunk. The doctors identify stage IV, the final stage, when the obviousness of the diffusion of cancer to other bodies (metastasis) is confirmed.

System of scaffolding of TNM

Stage I of the system of TNM implies the lining of the lung, the pericardium, or the right or left diaphragm on the same side. At this stage, the lymphatic ganglia are not implied. Stage II starts when
