If You Have Malignant Mesothelioma

Cancer can start anywhere in the body. Malignant mesothelioma is cancer that begins in the linings of certain parts of the body. This cancer occurs more often in the lining of the chest or abdomen (belly). It occurs when cells in the lining grow out of control and outnumber normal cells. This makes it difficult for the body to function the way it should.

Cancer cells can spread to other parts of the body. Cancer cells in the lining can sometimes travel to nearby organs and tissues and grow there. When cancer cells spread, what is known as a metastasis occurs. For doctors, the cancer cells at the new site are identical to those in the lining.

Cancer is always named after the place where it started. Therefore, when mesothelioma in the chest spreads to the spine (or anywhere else), it is still called mesothelioma. It can only be called bone cancer if it has started from cells in the bones of the spine.

Different types of mesothelioma
  •     Pleural mesothelioma begins in the chest (chest) around the lungs. This is by far the most common type.
  •     Peritoneal mesothelioma begins in the lining of the abdomen or belly.
  •     Pericardial mesothelioma begins in the lining that covers the heart.
  •     Vaginal tunic mesothelioma begins in the covering around the testicles.

Mesothelioma is also grouped into 1 of 3 types based on the appearance of the cancer cells:
  •     About half of all mesotheliomas are epithelioids and tend to have a better prognosis.
  •     Sarcomatoid or fibrous tumors are about 1 in 10 mesotheliomas.
  •     Mixed or biphasic tumors have parts that look like the other two types. Approximately 3 or 4 out of 10 cases are of this type.

Questions for the doctor
  •     Why do you think I have mesothelioma?
  •     Where is it located?
  •     Is there any chance it is not cancer?
  •     Can you write down the type of mesothelioma that you think I might have?
  •     What's next

General Information about Malignant Mesothelioma

Malignant mesothelioma is a disease in which malignant (cancerous) cells form in the lining of the chest or abdomen. Malignant mesothelioma is a disease in which malignant (cancer) cells are found in the pleura (the thin layer of tissue that lines the chest cavity and covers the lungs) or the peritoneum (the thin layer of tissue that lines the abdomen and covers most of the organs of the abdomen). Malignant mesothelioma can form in the heart or testicles, but this is not common Exposure to asbestos can influence the risk of malignant mesothelioma. Anything that increases the risk of getting a disease is called a risk factor. Having a risk factor does not mean you are going to have cancer; Having no risk factors does not mean you will not have cancer. Talk to your doctor if you think you may be at risk. Most people with malignant mesothelioma have worked or lived in places where they inhaled or swallowed asbestos. After exposure to asbestos, it usually takes a lon...

Mesothelioma Treatment

Mesothelioma treatment depends on the stage of the disease is, and you can tell that there is no standard treatments because of the smallness of their impact. The following therapies are currently used: Surgery Surgery with curative intent is, in theory, the best choice for the treatment of mesothelioma, however, complete resection (with large and negative margins) is rarely achieved. Less than 25% of the operated patients remain alive at 5 years. We have the following options:   Extrapleural pneumonectomy: is bloc resection of the parietal pleura and visceral, along with the lung infiltrated by the tumor, mediastinal lymph nodes, diaphragm and pericardium. All this is reconstructed meshes. It is a very complicated technique that is not done in all centers and having a high perioperative morbidity and mortality (in highly selected cases and expert hands is 4%). It has an average survival between 9 and 19 months and a survival rate at two years between 9...

What is Mesothelioma and Causes

Mesothelioma is a tumor derived from mesothelial cells of the pleura, peritoneum, pericardium and tunica albuginea. The mesothelium is a membrane that covers all our cavities inside. Pleural is the most common location (80%), affecting the pleura diffusely. The pleura is the membrane that covers the rib cage and the surface of the lungs. It is a rare tumor. It occurs between the 5th and 7th decade of life due to prior occupational exposure to asbestos or asbestos (a mineral) in youth. The incidence is highest in Australia, Belgium and Britain (with more than 20 cases per million inhabitants). The incidence is higher in men than in women. The mean survival of those affected by malignant mesothelioma is between six and 18 months. Causes of Mesothelioma The trade-name asbestos mineral formed by silica, magnesium oxide ferroso- lime and is the leading cause of mesothelioma, having proven carcinogenic potential in animals. In humans it has been shown that the risk is prop...
