The asbestos industry caused a great amount of pain to many families by ignoring the startling evidence that asbestos exposure is harmful and often deadly. All of the suffering could have been avoided because the asbestos companies knew a lot more than they informed the public about. The companies considered the protection of the industry more important than the lives of their workers.
Back in the 1920s, a large variety of medical articles showed that there was scarring on the lungs of asbestos factory workers. This evidence was revealed during autopsies of those workers. Asbestos companies had full knowledge of these articles, but chose to ignore the facts presented because the public reaction to such information would kill the asbestos industry. Further studies in the 1930s revealed that asbestos miners and factory workers were indeed dying of lung disease and cancer. There was enough evidence to support an undeniable correlation between asbestos exposure and the development of mesothelioma. Sadly, the companies decided to suppress this overwhelming evidence and in a series of letters between asbestos companies. In these same letters, executives revealed how far the companies were willing to go in order to protect their own interests. These letters that were circulated in the 1930s are called the “Sumner Simpson Papers.” In these letters, certain asbestos company executives made statements such as “the less said about asbestos, the better off we are.” Owens Illinois and Owens Corning Fiberglas conducted studies in the 1940s, attempting to prove that asbestos exposure was harmless, and save the asbestos industry. The studies revealed the exact opposite. They showed that exposure to asbestos was indeed quite harmful and even deadly. In light of the studies, the companies attempted to force scientists to change their conclusions.
Asbestos companies had full knowledge of the potential harm that could be caused by exposure to asbestos. Scientists and studies confirmed that there was a direct relationship between asbestos exposure and early death. Asbestos companies first tried to cover up the knowledge and silence scientists who conducted studies showing the harmful effects of asbestos exposure. Once the information about asbestos came to the public, these same companies attempted to deny having knowledge that people simply working around asbestos-containing products would suffer. The companies denied knowledge in order to avoid lawsuits. The simple fact is that asbestos-containing products cause serious injury and often lead to premature death. For this reason, mesothelioma lawsuits are quite valid and are in no way frivolous. Lung disease, lung cancer, and mesothelioma all stem from asbestos exposure. Many lives could have been saved if the asbestos companies were willing to release the information that they had access to.

Mesothelioma - An Asbestos Related Lung Cancer
by: Jill Kane
What is Mesothelioma?
Mesothelioma is a form of cancer located in the lining of either the lungs, abdomen or the heart. These linings are thin layers of tissue covering the organ.
The pleura is the tissue covering the lungs and the wall of the chest cavity which cushions and protects the lungs. The peritoneum lines the abdominal wall and surrounds most of the organs in the abdomen. The pericardium is the tissue surrounding the heart.
Mesothelioma is a rare but very serious cancer. There are three types of mesothelioma based on the types of cancerous cells. The most common type is epithelioid and consists of 50-70% of total cases and has the best prognosis. The second type is called sarcomatoid, consists of 10-20 % of mesothelioma cases and is more unpredictable in nature. The third type of mesothelioma is called biphasic, it is a combination of the other two types and consists of 20-35% of all cases.
There are an estimated 2000-3000 new cases of mesothelioma in the United States every year. The majority of these cases begin in the chest wall (pleural mesothelioma), a few start in the abdomen (peritoneal mesothelioma) and very rare are the cases starting in the lining surrounding the heart (pericardial mesothelioma).
The pleura is a thin lining of mesothelial cells. There are two pleuras in the chest, the parietal pleura and the visceral pleura. The parietal pleura lines the chest wall including the inside of the ribs, diaphragm and pericardium. The visceral pleura covers the lungs and filters fluid to and from the chest. If the pleura becomes diseases it is not effective at eliminating fluid from the chest resulting in pleural effusion or too much fluid in the chest.
Mesothelioma is usually the result of exposure to asbestos. Most people who are diagnosed with mesothelioma have had jobs where they breathed asbestos fibers. It may take up to 60 years from the time of asbestos exposure until mesothelioma develops.
Although rare, mesothelioma is a serious form of cancer which is often in its advanced stage when a diagnosis is made. In general, prognosis for mesothelioma patient is poor, however, some patients live with the disease for a long time. As mentioned earlier, the type of mesothelioma has an impact on the prognosis, as well as, the age of the patient, how much tumor has developed and if treatment is rendered. There are many variables in evaluating a mesothelioma case, so only the patients doctor can determine the best treatment and possible prognosis on an individual basis.

What Are The Four Stages of Mesothelioma Cancer?
by: David Arnold Livingston
One rare form of cancer is called Mesothelioma, a malignant tumor in the mesothelial tissues of the lungs and the abdomen, arising from the inhalation of asbestos. Its rarity is one of the reasons why a lot of people are not aware of this kind of fatal disease. In fact, many people die of Mesothelioma undiagnosed. Although there is now a growing awareness of the hazards of asbestos to health, still many have not heard of Mesothelioma and thus, have not understood its nature, cause, signs and treatment. Even some physicians find it hard to detect Mesothelioma because its symptoms are akin to other diseases like lung cancer and pneumonia. Furthermore, it takes decades for a patient who was exposed to asbestos to develop Mesothelioma — fifty years, at most.
Being unaware of Mesothelioma poses higher risks since it deters diagnosis and treatment. A person undergoing treatment must know the different stages of the cancer or the extent of the disease. Chances of recovering from Mesothelioma and the kind of treatment depend on the stage of the illness. There are basically two staging systems used for Pleural Mesothelioma (lungs): TNM system and Brighan system. These staging systems are also used in other kinds of cancers; however, the first is commonly used. There is no established method in determining the stage of the Peritoneal Mesothelioma cancer (abdominal) so the TNM system is used.
There are three variables in the TNM system: tumor, lymph nodes and metastasis. In the earliest stage of Mesothelioma, stage I, the malignant Mesothelioma cells start to grow and multiply only one layer of the pleura. The pleura is the membrane that encloses the lungs and lines the wall of the chest cavity. However, there are some instances wherein the pericardium (membrane that covers the heart) and diaphragm cover are already affected. In this case, the cancer patient is still in stage I Mesothelioma.
In the second stage, the two layers of the pleura are already affected by Mesothelioma. Take note, however, that in this stage, only one side of the body is affected. Normally, the pleura produces only small amount of lubricating fluid that allows easy expanding and contracting of the lungs. The excess fluid is absorbed by the blood and the lymph vessels so there’s a balance between the amount of fluid produced and removed. During the second stage Mesothelioma, fluid starts to build up between the membrane of the lungs and the membrane of the chest wall, resulting to pleural effusion. The increase in the volume of fluid produced causes shortness of breath and chest pain. Other Mesothelioma cancer patients experience dry and persistent cough. Diagnosis of the pleural effusion is achieved through a chest x-ray.
Stage III Mesothelioma means that the malignant cells have already spread to the chest wall, esophagus and the lymph nodes on one part of the chest. The patient may suffer severe pain near the parts affected. When not treated immediately or when the Mesothelioma patient doesn’t respond well to medication, the cancer may advance to the fourth stage. The fourth stage Mesothelioma is formidable since at this stage the Mesothelioma cells have penetrated into the bloodstream and other organs in the body like the liver, the bones and the brain. The lymph nodes on the other side of the chest may also be affected by Mesothelioma in stage IV.
Brighan staging system, on the other hand, determines whether the Mesothelioma can be surgically removed or not and whether the lymph nodes are affected or not. In stage I Mesothelioma, the lymph nodes are not yet affected and the patient can still recover through surgery. In stage II, surgery can still be executed but some lymph nodes have already been infiltrated by the cancer cells. In stage III, the heart and chest wall are already affected; thus, surgery is no longer advisable. The lymph nodes in this stage, however, may or may not be affected. In the final stage, stage IV Mesothelioma, cancer cells have already gone to the bloodstream and other parts of the body like the heart, brain, bone and liver. In most cases, a patient who has reached stage IV Mesothelioma only has four to twenty-four months to live.

Mesothelioma: Treatments for Mesothelioma Cancer
by: Hector Milla
Mesothelioma cancer is currently treated through three treatments, depending on the cancer location, the disease stage, and the patient's general health and age. These treatments are surgery, chemotherapy and radiation therapy, which sometimes are combined to fight the disease in so far as possible.
In a surgery, one of the most common treatments for mesothelioma, the doctor removes part of the lining of the abdomen or the chest and some tissue around it. In a pneumonectomy, the doctor may also remove one lung when the patient has pleural mesothelioma or cancer of the pleura. In other surgical procedure, the doctor may also remove part of the diaphragm, the muscle below the lungs that helps with breathing.
Through these procedures, the medical specialist shall try to excise tumourous tissue arising from this cancer disease. As these operations will reduce the patient's respiratory capacity, the surgeon will evaluate the patient's ability to function after a lung tissue removal, before performing a pneumonectomy.
Another method to fight Mesothelioma is chemotherapy or the use of anticancer drugs to kill cancer cells throughout the body. These drugs are given to the patient by an intravenous procedure, an injection into a vein. Currently, experts are studying the effectiveness of intracavitary chemotherapy or the possibility of giving chemotherapy straight to the chest or abdomen.
Radiotherapy or radiation therapy is the use of high-energy rays to destroy malignant cells and shrink tumors. It is important to know that this medical procedure attacks the cancer cells only in the treated area. There are two ways of giving this therapy. One, external radiation, in which the radiation comes from a machine, and other, internal radiation, where the cancer cells are found after putting materials that produce radiation into the affected area.
Doctor's way to relieve patient's pain is to use a needle or a thin tube to drain fluid that has built up in the abdominal or chest cavities through a procedure called thoracentesis, when it is from the chest, and paracentesis, when the removal is from the abdomen. The specialists may also give the drugs through a tube in the chest to prevent the accumulation of more liquid.

Mesothelioma Advice - Questions And Answers
by: Rick Hendershot
What is mesothelioma?
Mesothelioma is cancer of the mesothelium. Like most cancers, mesothelioma involves the abnormal dividing of cells of a particular part of the body -- in this case, the mesothelium. Mesothelioma is so deadly because it remains dormant for many years and then begins to rapidly expand. The cancer then begins to invade and damage nearby tissue, including the vital organs.
What is the mesothelium?
Many of the internal organs of the body are protected by a membrane called the mesothelium. This membrane actually consists of two layers of cells. The inner layer surrounds the organs, and the second is a sac surrounding the inner layer. When organs within this membrane must move, expand or contract -- such as the heart, lungs, bladder, and so on, they are able to do so because the mesothelium produces a lubricating fluid between the two layers.
Mesothelioma most often begins in the pleura or peritoneum. The pleura surrounds the lungs and covers the chest cavity. The peritoneum covers most of the organs in the abdominal cavity. Other mesothelium tissue is also vulnerable to mesothelioma. These include the pericardium that surrounds and protects the heart; the tunica vaginalis testic which surrounds the internal male reproductive organs; and the tunica serosa uteri which is the membrane covering the internal reproductive organs in women.
Who is at greatest risk to develop mesothelioma?
Mesothelioma has a very specific cause - exposure to asbestos. During the first half of the previous century, right up until the mid 1970s asbestos was an important material used to insulate buildings, machines, heavy equipment, and a broad range of commercial applications. Because it was plentiful and inexpensive to mine, asbestos was used in many 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, companies and health officials were slow to recognize the dangers of asbestos. As a result, shipyard workers, men and women working in asbestos mines and mills, workers producing asbestos products, workers in the heating and construction industries, and virtually all other tradespeople were exposed to asbestos fibres for extended periods of time.
Today it is understood that anyone working with or near asbestos has an increased risk of developing mesothelioma, so there are strictly controlled limits of exposure in the work place. But since the dormancy period of mesothelioma can often be 30 or 40 years, there are millions of workers who are at risk because of their exposure in the decades before the safety controls were put in place.
What are the symptoms of mesothelioma?
Pleural mesothelioma - cancer of the pleura or lung lining - causes shortness of breath or chronic coughing. 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.
Many of the symptoms of mesothelioma can easily be mistaken for allergies or a common cold. Mesothelioma is often discovered when patients think they have one of these other common illnesses.
How Serious is Mesothelioma?
By the time most infected people become aware they have mesothelioma, it is no longer dormant and becomes extremely aggressive. In its active phase, mesothelioma can travel quickly, and is almost impossible to stop. There are treatments used to keep the patient comfortable, but there is currently no cure for mesothelioma. 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.
This makes it extremely important to detect the disease before it enters its active phase.
How is mesothelioma diagnosed?
Mesothelioma is often not diagnosed until it reaches an advanced stage. This is because of its long dormancy period, and because once it becomes active the initial symptoms are similar to much more comman and less dangerous sicknesses such as colds or the flu. If a patient has a history of exposure to asbestos, then a complete physical examination is advised. This would normally include x-rays of the chest or abdomen and lung function tests. It might also include a CT (or CAT) scan or an MRI. Both of these tests give detailed pictures of areas inside the body.
If these tests indicate the probability of mesothelioma, then it is necessary to perform a biopsy to confirm the diagnosis. Doing a biopsy involves an oncology specialist taking a small sample of affected tissue and examining it under a microscope for signs of malignancy. Depending on the location of the affected tissue, doing a biopsy can be a relatively traightforward procedure. It normally involves the insertion of a small instrument into the suspect cavity. These surgical devices have both viewing and sample taking capabilities. So the oncologist or surgeon can look at the cavity from the inside, and then take tissue samples from different areas.
If mesothelioma is discovered, the initial tests are followed up with what is called "staging". This involves more tests to determine how far the disease has spread.
How is mesothelioma treated?
Standard treatments include the normal options available to cancer patients: surgery, radiation therapy, and chemotherapy. Sometimes, these treatments are combined. If the mesothelioma is discovered at an early enough stage these treatments can sometimes be effective.
Among the treatments that are used in order to reduce the effects of the disease are oxygen, postural drainage and pain killers. Many alternative treatment methods are also being tested, including attempts to strengthen the body's immune system. Gene therapy is also being tested in an attempt to attack the problem at the DNA level. Other treatments being tried and tested include homeopathy, herbs and acupuncture. Unfortunately none of these have been found to be very effective once the disease reaches its aggressive stage.
As with all cancers, early detection is the best defense against mesothelioma. Anyone who has been exposed to asbestos should be alert for symptoms and contact a doctor immediately. Detecting mesothelioma at the earliest stage possible greatly increases the chances of beating the disease.
