Mesothelioma cancer is a type of cancer that attacks the lungs and chest cavity. Also known as asbestos lung cancer, it forms deadly tumors where mesothelial cancer cells form a protective lining over the lungs, heart, and abdominal organs. It is a type of lung cancer that takes many years to develop and produce symptoms. Roughly 3,000 cases per year (mostly men over the age of 40) are reported. It is estimated that number will grow to about 300,000 cases before 2030.
Types of Mesothelioma Asbestos Cancer
Epithelial mesothelioma is a rare and fatal form of cancer affecting the membrane lining of the chest cavity, heart, lungs, and abdominal cavity. There are three forms of epithelial mesothelioma: the most common is Pleural Mesothelioma, the second most common, Peritoneal Mesothelioma (accounting for only a quarter of the cases), and the rarest form, pericardial mesothelioma.
Pleural mesothelioma, the most common type of this disease involves the pleura, a thin membrane located between the lungs and the chest cavity. The pleura provide a lubricated surface so that the lungs do not rub and chafe against the chest walls. There are two types of pleural mesothelioma the first being 'diffuse and malignant'. This type is cancerous and is generally fatal within a year of diagnosis. The second type is 'localized and benign' and is generally non-life threatening. It can usually be removed through surgery.
Lung Lining cancer is not to be confused with lung cancer. In lung lining cancer, the effected area of the body is called the mesothelium, a thin membrane that covers many of the internal organs of the body. The mesothelium of the lungs is called the pleura. Lung Lining cancer is also sometimes called mesothelioma after the area in which it occurs.
This thin membrane is comprised of two layers - one that surrounds the organ and another that forms an exterior sac around the first layer. Between the layers of the mesothelium is a fluid that allows vital organs to glide easily against objects that come in contact with them.
Localized pleural mesothelioma is not always caused by asbestos exposure. However, if it has spread to other parts of the body, for instance the lymph nodes, lungs, chest wall, or abdominal organs, then it is considered malignant and is more often than not the result of asbestos exposure.
Peritoneal mesothelioma appears as a tumor in the peritoneum membrane of the abdomen. This type of mesothelioma is very rare, comprising less than a fourth of all known cases of the disease. There are no effective treatments for this condition, and most patients live less than a year after diagnosis.
Mesentery cancer is likened to peritoneal cancer (mesothelioma). This cancer primarily affects the sections of the peritoneum that attach different organs to the wall of the abdominal cavity, (i.e. mesogastrium for the stomach, mesojejunum for the jejunum). Mesentery cancer includes all abdominal peritoneal extensions. Tumors rarely originate in the actual mesentery, though it is a frequent route for the spread of mesothelioma through the abdominal cavity.
Pericardial mesothelioma is the rarest form of mesothelioma, affecting the membrane around the heart (called the pericardium or pericardial sac). In this disease, solid masses and effusion (fluid) develop around the pericardium. Not all effusions are strictly related to mesothelioma.
The Causes
Mesothelioma cancer is caused by exposure to asbestos fibers or dust. Workers in the asbestos industry are prime targets for attracting this deadly disease. Asbestos fibers enter the body, either by breathing in the tiny asbestos fibers or by swallowing them. The fibers cause healthy cells to mutate into cancer. Since the body is unable to dispel these fibers, the lungs become inflamed (asbestosis). This condition worsens and eventually becomes malignant. Asbestos exposure is thought to be responsible for roughly 75% of all cases of lung lining cancer.
Symptoms
Mesothelioma is a very difficult cancer to detect in early stages. The early symptoms tend to be generic and even nonexistent in some cases, and it can take as much as 15 to 50 years after exposure to develop. The first symptom is often constant chest pain, followed by coughing, lung damage, and shortness of breath. Patients who have peritoneal mesothelioma (a less common form of mesothelioma) generally experience abdominal pain, loss of appetite, nausea, and abdominal swelling, often in addition to the symptoms of pleural mesothelioma. They may also develop bowel obstruction or further breathing obstruction.
Stages and Diagnosis of Mesothelioma
There are three staging systems used to determine treatment for mesothelioma: Butchart System, TNM System, and the Brigham System
Butchart Staging System
The Butchart System is the oldest system and the most common. This system concentrates upon determining the extent of primary tumor mass and divides mesothelioma into four stages.
Stage I of the Butchart System consists of the presence of mesothelioma in the lining of the right or left lung and may also involve the diaphragm on the same side. Stage II includes the progression of mesothelioma into the chest wall, esophagus, or lung lining on bother sides. There may also be lymph nodes in the chest. The onset of Stage III begins when the mesothelioma surpasses the diaphragm into the lining of the abdominal cavity or peritoneum. In this stage the cancer may also affect the lymph nodes extending beyond those in the chest. Doctors identify Stage IV, the final stage, when evidence of the spread of cancer to other organs (metastasis) is confirmed.
TNM System
Stage I of the TNM System involves the lining of the right or left lung, pericardium, or diaphragm on the same side. At this stage, lymph nodes are not involved. Stage II begins when mesothelioma spreads from the lining of the lung on one side to a lymph node on the same side. At this stage, the cancer may also spread to the lung, pericardium, or diaphragm on the same side. Stage III begins when mesothelioma is present in the chest wall, muscle, ribs, heart, esophagus, or other organs in the chest on the same side as the primary tumor. In the final stage, Stage IV, the mesothelioma has travelled into the lymph nodes in the chest on the side opposite the primary tumor, into the lung opposite the primary tumor, or directly into the organs in the abdominal cavity or neck. Metastasis is the final result in this stage.
Brigham System
The Brigham System determines the resectability (the ability to surgically remove) the mesothelioma mass. In Stage I the tumor is resectable, while lymph nodes remain unaffected. In Stage II the tumor remains respectable but the mesothelioma affects the lymph nodes. In Stage III the tumor becomes unresectable. It has penetrated through the diaphragm, or peritoneum. Stage III can occur with or without lymph involvement and extends into the chest wall and heart. Stage IV occurs when doctors discover metastatic disease involving distant organs.
After doctors identify the stage of a patient's malignant mesothelioma, the patient and doctor consider the various treatment options available. Mesothelioma treatment programs are contingent upon many factors, including the stage of the cancer, the location of the cancer, the spread of mesothelioma cancer, the characteristics of the cancer cells under a microscope and the patient's age and concerns.

Understanding and Recognizing the Symptoms of Mesothelioma: By Alan Hood
What is Mesothelioma?
Mesothelioma is a serious malignant tumor that affects the torso of the human body. There is a strong link between mesothelioma and contact with asbestos particles via breathing or swallowing.
There are three common forms of mesothelioma:
1. Pleural Mesothelioma is the most common form of Mesothelioma. It starts in the chest cavity (after breathing the particles) before spreading to other areas.
2. Peritoneal Mesothelioma starts in the abdomen (after swallowing the particles) and accounts for about 10-20% of Mesothelioma patients.
3. Pericardial Mesothelioma is the rarest form of Mesothelioma. It starts in the cavity that surrounds the heart.
Mesothelioma is difficult to diagnose early on because the symptoms are often mistaken for those of other, less serious ailments. To make matters worse, it often takes many years for the symptoms to show up after the contact with asbestos takes place. Individuals with a history of extended asbestos exposure are at the highest risk for developing malignant mesothelioma. Even a small exposure to this cancer-causing material can result in malignant mesothelioma. However, mesothelioma has a latency of up to thirty-forty years, and many individuals previously exposed to asbestos are now displaying symptoms. This means the average age of mesothelioma patients is between 50 and 70 years. Men are typically affected more, because of the common presence of asbestos in industrial settings. There are three major types of malignant mesothelioma. Epithelial, sarcomatoid, and mixed. Epithelial mesothelioma is most common. Symptoms may include, but are not limited to respiratory distress, a lasting cough, and pneumonia. In addition, symptoms are often mistaken for less serious ailments, and many patients do not show any signs at all.
Individuals with pleural mesothelioma may amass some fluid between the lung lining and chest cavity. This can be detected through a chest x-ray, as well as CT scans.
Diagnosis of Mesothelioma is based on a biopsy. This exam will test a tissue sample for the presence of malignant and/or pleural mesothelioma.
Causes of Mesothelioma
Asbestos is the principal cause of Mesothelioma. Asbestos is a type of insulation material, which was commonly utilized in the past in the following industries:
Steel Workers
Brake Mechanics
Insulators
Boilermakers
Ship fitters
Maintenance Workers
Pipe Fitters
Construction industry
Shipbuilding industry
Automotive industry
Other manufacturing industries
Mesothelioma appears most often in people who worked in the above industries and were exposed to asbestos in their workplace. The utilization of asbestos was very prevalent after 1940’s. However it would take 10-40 years after the first exposure for the first symptoms of mesothelioma to become noticeable, which made it very difficult to diagnose. The peak in mesothelioma cases is projected to be reached near year 2010 according to studies. There are three frequently used types of asbestos: white, brown, and blue. Brown and blue asbestos are more frequently associated with mesothelioma. These types of asbestos have been restricted by most countries in the 1990s. A record of asbestos exposure at work is reported in about 70 percent to 80 percent of all cases.
Asbestos is a very dangerous material and can cause serious damage to your health. It is made up of very minute fibers, which can find their way to pleura (outside lining of the lung) and damage the cells pleura are made of. These fibers can also be passed on to clothing, which makes them dangerous not only to the person exposed to asbestos, but to their family members as well.
Smoking
Smoking does not appear to increase the risk of mesothelioma. However, the combination of smoking and asbestos exposure drastically increases a person’s risk of developing cancer of the air passageways in the lung.
Symptoms of Mesothelioma
Symptoms of mesothelioma may not materialize until 30 to 50 years after exposure to asbestos. Shortness of breath and pain in the chest due to an accumulation of fluid in the pleura are often symptoms of pleural mesothelioma. Symptoms of peritoneal mesothelioma include weight loss and abdominal pain and swelling because of a buildup of fluid in the abdomen. Other symptoms of peritoneal mesothelioma may include bowel obstruction, blood clotting abnormalities, anemia, and fever. If the cancer has spread beyond the mesothelium to other parts of the body, symptoms may include pain, difficulty swallowing, or swelling of the neck or face. These symptoms may be caused by mesothelioma or by other, less serious conditions. It is important to see a doctor about any of these symptoms. Only a doctor can make a diagnosis. Once Mesothelioma is diagnosed, the likelihood of recovery varies according to several factors, including the size and location of the tumor, how much it has spread, and the age of the patient.
In general, the earlier that Mesothelioma is diagnosed, the greater the likelihood of survival. If you feel that you have experienced any of the typical Mesothelioma symptoms, pay a visit to your doctor for professional advice.
Mesothelioma diagnosis
Diagnosing mesothelioma is often complicated, because the symptoms are similar to those of several other conditions. Diagnosis begins with an assessment of the patient’s medical history, as well as any history of asbestos exposure. A physical examination may be performed, including x-rays of the chest or abdomen and lung function tests. A CT (or CAT) scan or an MRI may also be useful. A CT scan is a series of detailed pictures of areas inside the body created by a computer linked to an x-ray machine. In an MRI, a powerful magnet linked to a computer is used to make detailed pictures of areas inside the body. These pictures are viewed on a monitor and can also be printed.
A biopsy is needed to confirm a diagnosis of mesothelioma. In a biopsy, a surgeon or a medical oncologist (a doctor who specializes in diagnosing and treating cancer) removes a sample of tissue for examination under a microscope by a pathologist. A biopsy may be done in different ways, depending on where the abnormal area is found. If the cancer is in the chest, the doctor may perform a thoracoscopy. In this procedure, the doctor makes a small cut through the chest wall and puts a thin, lit tube called a thoracoscope into the chest between two ribs. Thoracoscopy allows the doctor to look inside the chest and obtain tissue samples. If the cancer is in the abdomen, the doctor may perform a peritoneoscopy. To obtain tissue for examination, the doctor makes a small opening in the abdomen and inserts a special instrument called a peritoneoscope into the abdominal cavity. If these procedures do not yield enough tissue, more extensive diagnostic surgery may be necessary.
If the diagnosis is mesothelioma, the doctor will want to learn the stage and extent of the disease. Staging involves more tests in a precise effort to find out whether the cancer has proliferated and, if so, to which parts of the body. Knowing the stage of the disease helps the doctor plan treatment. Mesothelioma is described as localized if the cancer is found only on the membrane surface where it originated. It is classified as advanced if it has extended beyond the original membrane surface to other parts of the body, such as the lymph nodes, lungs, chest wall, or abdominal organs.
Mesothelioma treatment
Treatment for mesothelioma depends on the location of the cancer, the stage of the disease, and the patient’s age and general well being. Typical treatment options consist of surgery, radiation therapy, and chemotherapy. Sometimes, these treatments are combined.
Surgery is a frequent treatment for mesothelioma. The doctor may remove part of the lining of the chest or abdomen and some of the tissue around it. For cancer of the pleura (pleural mesothelioma), a lung may be removed in an operation called a pneumonectomy. Sometimes part of the diaphragm, the muscle below the lungs that helps with breathing, is also removed.
Radiation therapy involves the use of high-energy rays to kill cancer cells and shrink tumors. Radiation therapy affects the cancer cells only in the treated area. The radiation may come from a machine (external radiation) or from moving materials that produce radiation through thin plastic tubes into the area where the cancer cells are found (internal radiation therapy).
Chemotherapy is the use of anticancer drugs to kill cancer cells throughout the body. Most drugs used to treat mesothelioma are given by injection into a vein (intravenous, or IV). Doctors are also studying the effectiveness of applying chemotherapy directly into the chest or abdomen (intracavitary chemotherapy).
To ease symptoms and control discomfort, the doctor may use a needle or a thin tube to drain fluid that has accumulated in the chest or abdomen. The procedure for removing fluid from the chest is called thoracentesis. Removal of fluid from the abdomen is called paracentesis. Drugs may be administered through a tube in the chest to prevent more fluid from accumulating. Radiation therapy and surgery may also be beneficial in alleviating symptoms.
Note of Urgency
Mesothelioma is a life-threatening disease and cannot be left untreated. The sooner it is diagnosed the better a patient’s chances are of fighting this deadly cancer. Please contact a qualified doctor immediately if you or someone you know has been diagnosed with mesothelioma.

Mesothelioma - Your Basic Information: By William Johnston
Mesothelioma is a form of cancer that is becoming more and more common. The most common cause of this cancer is exposure to asbestos. When constantly exposed with insufficient protection, asbestos dust and fibres affect the mesothelial cells which make up the mesothelium. The mesothelium is the outer lining that protects some of the body’s most vital organs such as the heart and lungs. The mesothelial cells become abnormal after lengthy periods of constant exposure to asbestos causing an array of problems.
Due to the latency period and symptoms of this cancer, mesothelioma is very difficult to diagnose. Mesothelioma takes decades to mature and develop fully and this is why many elderly men who were exposed to asbestos thirty years before are just discovering they have the cancer. A lot of these men are currently lodging multi-million dollar lawsuits against the companies that exposed them to the dangers of asbestos without sufficient protection.
The organs that are affected most by mesothelioma are the lungs. The most common type of mesothelioma which is called pleural mesothelioma affects the lining of the lungs and can cause symptoms such as coughing, breathing and swallowing difficulties, shortness of breath and fever. Another area that can be affected by mesothelioma is the abdomen. This is less common and this is known as peritoneal mesothelioma. Symptoms of peritoneal mesothelioma include nausea and vomiting, weight loss, fever, bowel obstruction, loss of appetite and general pain in the stomach area. The last and least common type of mesothelioma is known as pericardial mesothelioma and it affects the heart and the tissue surrounding it. Symptoms of this form of the cancer include palpitations, breathing difficulties and persistent coughing. Generally, the symptoms of mesothelioma are typical of many other diseases and this makes it very difficult to diagnose.
There are treatments for mesothelioma although these are usually unsuccessful. If the cancer is treated aggressively in its early stages then there is a good chance of a patient surviving. However, due to the difficulty to diagnose mesothelioma, the cancer is not normally found until it is too late. Treatments that are used for mesothelioma include surgery, radiation therapy, palliative therapy and chemotherapy. Research for additional treatment of mesothelioma is being done at various cancer centers all over the United States as well as by pharmaceutical companies.

Mesothelioma Surgery : By William Johnston
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.

Mesothelioma - Catch It Early to Avoid Big Trouble : By Rick Hendershot
Mesothelioma is a relatively rare form of cancer where cancerous cells develop in the mesothelium -- a protective sac that covers most of the body's internal organs. Like most cancers, early detection of mesothelioma greatly increases the chances of beating the disease.
But early detection is more difficult with mesothelioma because it has a long dormancy period of 30 or 40 years in which the cancer remains fairly inactive and causes very few symptoms. When the disease passes into its active phase it rapidly spreads to the internal organs such as the lungs, heart and abdominal organs. In its active phase it is very difficult to treat successfully because it develops and spreads so quickly.
Causes of mesothelioma
Mesothelioma was barely in the public eye until a few years ago. It has a very specific cause -- exposure to asbestos. And the dangers of asbestos exposure were not widely acknowledged until the 1970s and 80s when its serious health implications could no longer be ignored.
As often happens in cases involving commercial products with harmful side effects, there was tremendous resistance to acknowledging its dangers. In the case of asbestos, it was a product that had some very important properties that made it ideal for insulation applications.
During the first half of the previous century, right up until the mid 1970s asbestos was the default material used to retard heat transfer in buildings, machines, heavy equipment, and a broad range of commercial applications. Because it was plentiful and inexpensive to mine, asbestos was widely used in building products such as home insulation, floor, ceiling and roof tiles. It was also used in commonly found commercial products such as brake linings and pipe insulation.
This meant that millions of people were coming in contact with asbestos on a daily basis. And since the effects of exposure to asbestos fibre often do not become apparent for 30 or 40 years after prolonged exposure, there often appeared to be no immediate health risk.
This was especially important in the case of workers who mined and processed asbestos. Although workers were regularly getting sick and often had premature, painful deaths, the long period of dormancy of mesothelioma made it difficult to make the connection to asbestos.
Even short term asbestos exposure will cause mesothelioma
Generally, the probability of developing this form of cancer is directly related to the length of time you are exposed to asbestos. The health risk also increases with the intensity of the exposure to asbestos.
However, an exposure of as little as one or two months can result in mesothelioma 30 or 40 years later. At the age of 48, Canadian Member of Parliament Chuck Strahl, was recently diagnosed with mesothelioma and traces the cause back to changing brake pads on logging equipment after he graduated from high school. Strahl's case is a good example of the fact that Mesothelioma has a latency period of anywhere from 20 to 50 years. Like thousands of others he developed the disease long after his exposure to asbestos.
Symptoms of mesothelioma
Because of its long dormancy period, mesothelioma is often not detected until it enters its active, aggressive stage. Pleural mesothelioma - cancer of the lung lining - causes shortness of breath or chronic coughing. Unfortunately these symptoms can easily be mistaken for allergies or a common cold.
In fact pleural mesothelioma is often discovered by accident when patients think they have one of these more common illnesses. Other symptoms of pleural mesothelioma may include chest pain, chronic coughing, shortness of breath, fatigue, wheezing, hoarseness, weight loss, or blood in the phlegm from the lungs when coughing.
Peritoneal mesothelioma affects the lining around the stomach and intestines and is usually just as dangerous. Symptoms of peritoneal mesothelioma include pain or swelling in the abdomen, weight loss, bowel obstruction, anemia, and fever.
Treatment of mesothelioma
Unfortunately, by the time most infected people become aware they have mesothelioma it has ceased being dormant and becomes extremely aggressive. Once it is no longer dormant, this type of cancer can travel quickly, and it becomes almost impossible to stop.
While there are treatments that are available in order to keep the patient comfortable, there is currently no cure for mesothelioma, and as many as 75% of those who develop the disease will lose their life within one year. The remainder may last for up to an additional six months.
Among the treatments that are used in order to reduce the effects of the disease are oxygen, postural drainage and pain killers. A wide range of treatment approaches are being tested, ranging from attempts to fortify the body's natural immune system to gene therapy which tries to attack the problem at the DNA level. Homeopathy, herbs and acupuncture are also used. But none have yet been shown to be very effective once the disease reaches the aggressive stage.
Given the generally poor prognosis for people who do not catch the disease in time, early detection is the best defence against mesothelioma. If you have worked in an industry such as construction or suspect that you may have been exposed to asbestos, be alert for symptoms and contact your doctor immediately. Like all forms of cancer, detecting mesothelioma at the earliest stage possible greatly increases your chances for survival.

Mesothelioma Cancer and Asbestos : By Michael Wong
Mesothelioma is a form of cancer which occurs in thin membranes (called the mesothelium) lining the chest, lungs, abdomen and sometimes the heart. Although quite rare, mesothelioma symptoms strike more than 200 people each year in the United States. The majority of mesothelioma cases are directly linked to asbestos exposure.
Because of the long latency period of mesothelioma, the average age of patients is between 50 and 70 years. Mesothelioma affects men most due to the high exposure of asbestos in industrial typed jobs. Mesothelioma symptoms include respiratory problems, shortness of breath, continual cough and pneumonia. Other mesothelioma symptoms include weight loss, abdominal problems and swelling. In some mesothelioma patients, the mesothelioma symptoms are quite muted, making it hard for mesothelioma doctors to diagnose.
Mesothelioma doctors specialize in the study, research, and treatments of Mesothelioma cancers.
Mesothelioma (or the cancer of the mesothelium) is a disease in which cells become abnormal and replicate without control. During Mesothelioma, these cells will invade and damage tissues and organs. Mesothelioma cancer cells can spread throughout the body causing death.
Mesothelioma treatments and Mesothelioma clinical trials and tests
There are many mesothelioma treatment options available. Treatments include surgery, radiation therapy and chemotherapy and the mesothelioma treatment depends on the patient’s age, general health and stage of the cancer. There has been much mesothelioma research conducted throughout the past two years to find new treatment methods. Click here to read more about mesothelioma treatment techniques.
Through mesothelioma research, The National Cancer Institute has sponsored mesothelioma tests and clinical trials that are designed to find new treatment methods. Because of the increase in number of mesothelioma cases in the United States, both governments have increased funding for mesothelioma research. Mesothelioma research and clinical trials have been successful in developing new techniques to fight this cancer and the outlook for more advanced mesothelioma treatments is promising.
Surgery is the most common treatment method for malignant mesothelioma. Tissues and linings affected by mesothelioma are removed by the doctor and may include the lung or even diaphragm.
A second mesothelioma treatment method is radiation therapy through the use of high energy x-rays that kill the cancer cells. Radiation therapy can be outside or inside the body.
A third mesothelioma treatment method is chemotherapy. Through pills or drugs through needles, chemotherapy drugs are used to kill cancer cells.
A new mesothelioma treatment method is called intraoperative photodynamic therapy. In this treatment, light and drugs are used to kill cancer cells during surgery for early stages of mesothelioma in the chest. Although there are numerous treatments and drugs for mesothelioma, doctors are loosing the battle against this deadly disease. Most mesothelioma treatments involve old techniques combined with different drug cocktails. However, in most cases, these mesothelioma treatments have many side effects including organ damage, nausea, increase in heart failure etc. The rush to find a more effective mesothelioma treatment or even cure is ongoing at numerous clinical labs across the nation. Let's hope that the mesothelioma treatments will one day erradicate mesothelioma cancer and asbestosis.
With an abundance of information on the Internet, Mesothelioma Cancer and Asbestos (http://www.mesothelioma-cancer-and-asbestos.com) has consolidated the most important issues surrounding Mesothelioma, Mesothelioma doctors and symptoms, Mesothelioma treatment, Mesothelioma research and tests.
At http://www.mesothelioma-cancer-and-asbestos.com, the website contains useful resources on Mesothelioma lawyers and attorneys, as well as causes by asbestos exposure, asbestos removal, asbestos attorneys and lawsuits, and asbestos cancer. Patients stricken by Mesothelioma and their families require support and current information. Mesothelioma Online Resources hopes to educate and give hope to survivors and victims.
Mesothelioma is such a harsh disease. Not only does it take years for symptoms to appear, but there are limited treatements and drugs that will prolong the lives of workers stricken with mesothelioma. In many cases, the death rate of mesothelioma is unfortunately very high. However, with increased funding in mesothelioma research through the government and private grants, the outlook for a mesothelioma cure is quite possible. In the meantime, mesothelioma support groups and local discussions provide the ongoing support for mesothelioma patients.
