When a person is exposed to asbestos, he or she inhales tiny asbestos fibres which are suspended in the air. These fibres pass into the respiratory system and end up becoming lodged in the lungs. An accumulation of asbestos fibres in the lining of the lungs like this can cause nearby cells to deform and eventually leads to what is known as pleural mesothelioma. Accumulation of asbestos fibres in the peritoneum (lining of the abdomen) can lead to peritoneal mesothelioma and build up of fibres around the tissue of the heart can cause pericardial mesothelioma. Asbestos fibres reach these places over time or because they have been transported there by the lymphatic system.
Mesothelioma has a very large latency period (time between getting the cancer and feeling the symptoms of it). This period is usually between 30 – 50 years and so a person who bears mesothelioma is unlikely to know that they have got it. This is why mesothelioma is so hard to diagnose in its early stages because it shows no symptoms and the few symptoms that it does show such as wheezing and shortness of breath are typical of far more common diseases such as pneumonia. The likelihood of being cured depends largely on how early and how aggressively the cancer is treated. If it is treated when it has fully developed and matured then it is extremely difficult to cure.
In this way, those at risk are those who have worked amongst asbestos. Construction workers, asbestos manufacturers or those who have lived within a mile of an asbestos factory are the people who have the largest contact with asbestos. Those who are in contact with these people are also at risk because asbestos fibres can stick to clothes and hair. The majority of people who are discovering that they have mesothelioma are elderly men of about 60 – 70. This was the generation which worked with asbestos a lot without sufficient protection. Many of these men are now lodging multi million dollar lawsuits against the companies who exposed them to the dangers of asbestos.

The Biological Behavior of mesothelioma
The biological behavior of the mesotheliomas can be predicted by their gross look, those shape and structures .
solitary, discrete masses are generally benign, whereas those, which grow diffusely, are usually malignant. Mesothelioma is a tumor emerging from mesothelial lining of serous cavities, most often covering of lungs (the pleural cavity) , rarely, in coverings of abdomen (peritoneal cavity) and covering the heart (pericardial sac).
They are two types benign and malignant.
Mesothelioma – Benign or Solitary.Benign or solitary can also called by pleural fibroma. Exposures of asbestos play no role on the e etiology of benign mesothelioma. Entirely it consists of a solitary, circumscribed, small, firm mass and generally less than one inch in diameter. Dense fibrous tissues can be seen by cut the surface. The tumor is composed by predominantly of collage fibers and reticulin with interspersed fibroblasts. Unusual, mesothelial lined clefts are seen in the tumor. Benign mesothelioma causes tumor is associated with systemic syndrome of osteoarthropathy or hypoglycemia. Removal of the tumor is generally curative.
Mesothelioma – Malignant or diffuse.It is a highly malignant tumor with high mortality and it is rare. Usually after 20 to 40 years exposure to asbestos the tumor can be detected. Almost 90 percent of malignant mesotheliomas are asbestos related.

Mesothelioma Search For Hope
Mesothelioma research mean to the discovering studies new facts or information about mesothelioma cancers, Mesothelioma is a life threatening cancerous disease , It affects the lining of abdominal organs and lungs , Only known reason of this disease is exposure to asbestos particles. Diagnosis of mesothelioma is a difficult process. This is mainly because asbestos particles may lie dormant in the body for up to 50 years before appearance of symptoms. Average survival time of mesothelioma patients is 1-2 years. Mesothelioma research is important considering the increasing number of mesothelioma patients every year.
Key Points of Mesothelioma Research
Most of the mesothelioma research going on today is focused towards the effects of asbestos particles on human cells. Scientists undertaking mesothelioma research are studying the process through which asbestos corrupts the healthy cells of the body. Ongoing research about mesothelioma provides a ray of hope that sometime in the future it may become possible to prevent the damaging effects of asbestos particles on human cells.
During the course of mesothelioma research, experts are also performing clinical trials on the mesothelioma patients. They are conducting clinical trials on the patients who are diagnosed for mesothelioma cancers on early stages as well as later stages. Doctors emphasize on trials on both types of patients because both of them equally require relief from mesothelioma cancers. Ongoing mesothelioma research and newer information every day provides hope to mesothelioma victims that any trial can result into the discovery of an effective treatment for mesothelioma cancers.
Sponsors of Mesothelioma Research
Many organizations including the companies responsible for the exposure to asbestos particles are sponsoring mesothelioma research. It is the moral duty of those companies because many people are on brink of death because of their negligence. Law firms are also keeping a close watch on mesothelioma research because many patients are adopting legal course for seeking mesothelioma compensation. A mesothelioma law firm has better chances for getting compensation for its client if they better information about this dangerous disease.

Mesothelioma Surgery
Mesothelioma is a rare, deadly form of cancer which can occur in a number of types. Mesothelioma is caused by exposure to asbestos, a group of natural fibres which are extremely dangerous if inhaled as fibres. When fibres are inhaled they become lodged in the alveoli of the lungs and over a period of time these fibres make tissue and cells abnormal and cause mesothelioma cancer. Pleural mesothelioma is the most common form of mesothelioma cancer, accounting for approximately 75% of all mesothelioma cases. The next most common form, peritoneal mesothelioma, accounts for 20% of all mesothelioma cases and pericardial mesothelioma accounts for the remaining 5%. Pleural mesothelioma affects the lining of the lungs, peritoneal mesothelioma attacks the peritoneum, which is the lining of the abdomen and pericardial mesothelioma affects the tissue surrounding the heart. All three of these types of cancer occur in extremely important areas of the human body and this is one of the reasons why it is so difficult to treat. Treatment methods such as radiation therapy can only be conducted with strict radiation dosage restrictions due to the possibility of damaging a vital organ such as the lungs or the heart.
Aggressive mesothelioma surgery is undertaken only by the strongest of mesothelioma patients because weaker patients are at risk of death within the first month after the operation. An experienced doctor will evaluate a patient before deciding that surgery is the best treatment method. He will take into account age, medical record, disabilities, allergies, sex, even weight. The operation will then take place. Mesothelioma surgery consists of cutting open a patient and removing the majority of cancerous cells from either the lining of the lungs, abdomen or heart in an attempt to gain long term control over the cancer. Due to the proximity of the cancer to major organs of the body, the operation can only be performed by extremely skilled surgeons. There is a chance that a patient will die during the operation.
A second type of mesothelioma surgery is called palliative procedures. This is a far less dangerous and aggressive form of surgery which does not attempt to gain long term control over the cancer. Palliative procedures are designed to lessen the symptoms for a patient when it is almost certain that the patient will die inevitably from the cancer.
Mesothelioma surgery can also be coupled with radiation therapy and chemotherapy in what is known as dual therapy. Patients would undergo surgery to get rid of the majority of the cancerous mesothelioma cells and then chemotherapy and radiation therapy would be used to kill off any remaining cells. This combination of treatments has proved to be effective and has one of the highest success rates for treatments of mesothelioma cancer.
