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.

History of asbestos.

There are four main types of asbestos; Amosite (brown fibers), Anthophyllite (gray fibers), white Christie, and blue Crocidolite. Chrysotile has curly fibers while the other three have rod like fibers. These fibers fragment into dust quite readily and waft into the air. They can adhere to skin or clothing and are easily swallowed or inhaled.

Half a century ago, asbestos was hailed by many as a miracle product. They said nearly anything could be made from this mineral. It as used as an additive to reinforce mortar and plastics. Asbestos fibers can also be separated into fine threads that do not conduct electricity and are unaffected by heat or chemicals.

Use of asbestos drastically increased during World War II. Shipbuilding incorporated asbestos extensively in freighters and support vessels to insulate boilers, steam pipes and hot water pipes. Asbestos became the miracle construction material as it was readily obtained, processed, and transported. After WWII cars used asbestos in brake shoes and clutch pads. Asbestos found its way into residential and industrial building materials, water supply, sewage materials, ceiling and floor tiles, and vermiculite garden materials to name a few products.

In the 1970′s, following the discoveries of the health dangers of asbestos dust inhalation, the U.S Consumer Product Safety Commission prohibited the use of asbestos in several products that could liberate asbestos fibers into the environment during use. Regulations governing the use of asbestos and public concern since 1970 have created a significant drop in the use of asbestos in the United States. The same pattern has been seen in most of the developed world.

In 1989 all new uses of asbestos were banned by the Environmental Protection Agency while any old uses before that year were still allowed. The EPA suggested that schools inspect for damaged asbestos and eliminate any exposure or enclose it in protective barriers. Vermiculite, widely used in horticulture, became a concern of the EPA . They recommended outdoor use, limiting the amount of dust used, and keeping vermiculite damp.

Health hazards

Asbestos may create serious health hazards such as coughing, lung damage, shortness of breath, and lung cancer. Most people do not become sick in the early stages of contact but usually need continued exposure. This often means on jobs such as mining, milling, manufacturing asbestos products, and the building construction industry. Firemen, demolition and destruction workers, drywall removers, and anyone else involved in trades that involve destruction of buildings, ships, and automobiles are also exposed to the hazards of asbestos.

Over a number of years continual exposure to asbestos can cause very serious health problems, such as mesothelioma. Mesothelioma is a rare type of carcinoma of the membrane that lines numerous cavities of the body, including the lungs, abdomen and heart, and has been associated with exposure to asbestos dust. In mesothelioma, the cells of the mesothelioma metastasize and damage adjacent organs and tissues.

Mesothelioma may not develop for a long period of time, often as long as twenty-five or thirty-five years before full blown symptoms appear. Not all workers who have been exposed will develop diseases, but workers who have been exposed to it may bring fibers on their clothing, hair, shoes, and skin home to their families. To circumvent this risk, most industries require workers to bathe and change their clothing before they leave work.

Dietary advice for Mesothelioma patients

Doctors and nutritionists may recommend a special cancer diet because many mesothelioma patients tend to lose their appetites due to worry over their condition. Also, those who are undergoing treatment may choose not to eat because of the unpleasant side effects they may experience. Chemotherapy and some medications may cause an imbalance of nutrients that must be corrected in order to keep the body as strong as possible and to keep the patient from losing an excessive amount of weight. Other side effects of mesothelioma treatment can include nausea, vomiting, constipation,dry mouth and a change in the sense of smell or taste.

In our childhood we were all told to eat our vegetables. Forcing down cabbage and sprouts was supposed to make us bigger and stronger. Well, so it is for mesothelioma patients. Diet is often an overlooked subject for cancer patients, but eating the right nutritional foods for strength and energy is just as important as taking the proper medication.

Mesothelioma patients undergoing treatment must follow a special cancer diet devised by their nutritionists. The details of every patient’s mesothelioma diet will vary. Some patients will need to incorporate more fat into their diets, while others may need more protein. Cancer diets involve eating the correct amounts of protein and calories as well as drinking the right amount of water to keep the ailing body replenished and energized. The body needs plenty of nourishment when it is going through chemotherapy or even when the patient is taking certain medications.

It is important that patients devise a cancer diet under the guidance of their doctor and nutritionist to ensure that they obtain the proper amount of nutrients to improve their quality of life.

Protein is important for any cancer patient because it helps repair tissue damaged by surgery, chemotherapy, or radiation. Protein also helps maintain a strong and healthy immune system, lowering a mesothelioma patient’s risk of infection after aggressive cancer treatments. The National Cancer Institute recommends increasing protein in a cancer diet with cheese, milk, ice cream, yoghurt, eggs, nuts, peanut butter, meats and fish.

Fats are an essential part of the cancer diet because they supply the body with the necessary energy it needs while undergoing treatment. The amount of fats a cancer diet should consist of is dependent on a mesothelioma patient’s age and body size. The National Cancer Institute recommends increasing caloric intake with such foods as butter, milk, cheese, honey, sugar, granola and dried fruits.

Water is another essential component of the cancer diet. Without a significant amount of water, the body will dehydrate. It is important that anyone undergoing cancer treatment drink sufficient water to keep their bodies hydrated and replenished.

Many people have never heard of Mesothelioma and are unaware of its symptoms. Although considered a rare form of cancer, each year the number of cases grows. With the prevalence of this disease on the rise, it is critical to understand why and how Mesothelioma develops and what courses of action can be taken in the event of diagnosis. The following are some questions and answers that will provide you with information on Mesothelioma.

**What is Mesothelioma?**

Mesothelioma is a rare form of cancer in which malignant (cancerous) cells are found in the mesothelium, a protective sac that covers most of the body’s internal organs. The organs most commonly affected are the lungs, heart and abdominal organs. The most common form of Mesothelioma is Pleural Mesothelioma — cancer of the lung lining. But cancerous cells are also found in the lining of the abdominal cavity (the peritoneum) and the lining around the heart (the pericardium).

**What causes Mesothelioma?**

Mesothelioma is almost always caused by exposure to asbestos. Asbestos is often found in building materials used before the mid 1970’s. In addition, materials such as pipes, boiler insulation, floor, ceiling and roof tiles may contain asbestos. It is believed that even insignificant exposure to asbestos in environments such as asbestos mills, mines, shipping yards, some older Navy ships or even in patient’s homes can result in mesothelioma. In many cases mesothelioma does not occur for decades after initial exposure to this cancer-causing asbestos. 2000-3000 cases of mesothelioma per year are currently being diagnosed. Family members of workers exposed to asbestos can also contract this disease through exposure to the worker’s clothing. Like many other cancers, smoking greatly increases the risk of contracting mesothelioma.

**How much 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.

**What are the symptoms of Mesothelioma?**

Mesothelioma is a very subtle form of cancer providing only a few noticeable symptoms until it becomes extremely advanced. 75% of all mesolthelioma cases are Pleural mesothelioma – cancer of the lung lining. This type of cancer causes shortness of breath and/or chronic coughing that can easily be mistaken for allergies or a common cold. Mesothelioma is often discovered by accident when patients are being examined for these common symptoms. Other symptoms of pleural mesothelioma may include: chest pain, shortness of breath, chronic coughing that worsens over time, fatigue, wheezing, lung infection, hoarseness, weight loss, difficulty swallowing, chest or abdominal pain or blood in the phlegm from the lungs when coughing

Peritoneal mesothelioma affects the lining around the stomach and intestines and can be just as dangerous and deadly. Symptoms of Peritoneal mesothelioma include: pain or swelling in the abdomen, weight loss, bowel obstruction (blockage in the large or small intestines), anemia (reduced number of red blood cells) , and fever.

The onset of Mesothelioma is usually quite slow. Patients will begin to experience symptoms such as lower back pain and chest pain. Unfortunately, once Mesothelioma develops, it quickly becomes aggressive and treatment must be sought immediately.

**Can Mesothelioma be treated?**

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 this makes it 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 to homeopathy, herbs and acupuncture. 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.

What Is Mesothelioma?

Mesothelioma is a rare cancer that occurs in the tissue covering the stomach and bowels (peritoneal tissue) or in the tissue covering the outside surface of the lung (pleural tissue). 90% of the cases of Malignant Mesothelioma are caused by exposure to Asbestos.

What Is Asbestos?

Asbestos is a silicate mineral made up of masses of tiny fibers that are as strong as steel and are highly resistant to heat and chemicals. Fibers of Asbestos are inhaled or swallowed and are able to penetrate to the outside surface of the bowel or to the outside surface of the lung where they become trapped. These trapped fibers can cause a reaction that leads to Mesothelioma Cancer. Mesothelioma symptoms may not appear until about 20 or 40 years from first exposure to airborne Asbestos fibers.

Mesothelioma Treatments

Mesothelioma treatments include radiation to shrink cancer tissue or cells, chemotherapy to stop the reproduction of cancer cells, photodynamic therapy and some times, surgery to remove cancerous tissue.

You Are Entitled To Compensation!

People who, faced with Mesothelioma Diagnosis are entitled to compensation from the manufacturers of any asbestos-containing product to which they were exposed in sufficient quantities to cause disease.
