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.

For more mesothelioma cancer

Mesothelioma is a rare form of cancer that is usually found in those previously exposed to asbestos. Cancerous cells form in the mesothelium, which is a protective lining that covers most of the body’s internal organs. These cells typically form in the lining of the lungs, abdomen, or the sac that encircles the heart.

The average life span of a person diagnosed with the disease is about 4 to 24 months from the finding. About 3,000 people in the U.S. die of mesothelioma every year. People at risk are those who have been previously exposed to asbestos dust, including former steel workers, auto mechanics, mineworkers, and military workers, among many others. Their family members may also be at risk, as the asbestos dust from clothing can travel through the air.

Mesothelioma has an extremely long latency period, which means that symptoms of the disease may not emerge until 30 to 50 years after the initial exposure to asbestos. Pleural mesothelioma, which is the most common type and affects the area around the lungs, may cause shortness of breath, chest pains, and a persistent cough, which may lead to coughing up blood. These symptoms are caused by the build up of fluid between the lining of the lung and the chest cavity. The disease may start in the chest area and spread to other areas of the body. Other symptoms of pleural mesothelioma include weight loss, severe breathing trouble, fever, difficulty swallowing, and swelling of the face and neck areas. It should be noted that some people with the disease do not experience any serious symptoms at all.

Peritoneal mesothelioma is rarer than pleural mesothelioma, and affects the abdominal area. Symptoms of peritoneal mesothelioma include abdominal swelling and pain due to the build up of fluid in the abdominal cavity, nausea, loss of appetite, and vomiting. Breathing complications and chest pains may also be present, as well as bowel obstruction, anaemia, fever, and blood clotting.

The rarest form of the disease is pericardial mesothelioma, which first forms in the area surrounding the heart. Tumors grow in the tissues around the heart and spread from there. Chest pain, shortness of breath, constant coughing, and shivering may be symptoms of this form of mesothelioma.

Diagnosis of the disease is oftentimes difficult, due to the fact that the symptoms associated with mesothelioma are similar to those of other conditions. The symptoms of the disease become more serious as the cancerous tumors enter the later stages of development, so people who have been exposed to asbestos at any time in their lives should contact their doctor immediately. Even if a person has never been exposed directly to asbestos but is experiencing any of the above symptoms, they should inform their doctor as soon as possible, as asbestos dust and fibres may have traveled through the air from items such as clothing.

People who have been diagnosed with any form of mesothelioma should immediately contact a lawyer. Individual states have their own statutes of limitation, meaning that there is a set time limit regarding how long a patient has to act on their diagnosis. When searching for a lawyer to handle your case, be sure to find one that has prior experience with mesothelioma cases. They will have the contacts and resources to take care of your case in a timely manner. The Internet is a helpful and efficient resource for a mesothelioma lawyer search.

Patients do not have to be concerned with paying lawyers up-front, since the majority of mesothelioma lawyers work on a contingency fee basis, which means that they will not request payment of any kind unless they successfully settle your case. Lawyers will usually take a 35% cut of whatever settlement or reward the patient receives, but patients seeking compensation for their disease have nothing to lose and everything to gain in going to a lawyer for help.

The average mesothelioma-related settlement in the U.S. is $1 million. Cases that go to trial average awards of approximately $6 million, according to the RAND Corporation. A bill called the Fairness in Asbestos Injury Resolution Act of 2005 (FAIR Act of 2005) introduced on March 17, 2005, seeks to create set amounts of compensation for mesothelioma victims, which would depend on their symptoms.

People who have mesothelioma are able to seek large compensation amounts because their disease is a result of a company’s decision not to take sufficient measures to protect its workers from breathing in asbestos while on the job.

There are various symptoms of Mesothelioma cancer, but sometimes they don’t appear until 30 to 50 years after exposure to asbestos, hence the importance of following the series of recommendations for prevention of asbestos-related diseases among asbestos workers.

The most common Mesothelioma symptoms are shortness of breath and pain in the chest. These symptoms occur due to a buildup of fluid in the pleura, what is known as Pleural Mesothelioma. However the symptoms of Peritoneal Mesothelioma include weight loss, abdominal pain and swelling due to an accumulation of fluid in the abdominal cavity.

Peritoneal mesothelioma may include other uncomfortable symptoms too, such as bowel obstruction, blood clotting abnormalities, anemia and fever.

However these symptoms can appear before if malignant cancerous cells have spread beyond the mesothelium to other parts of the body, and other symptoms such as trouble swallowing, pain, and swelling of the neck or face may appear.

Mesothelioma or other less serious conditions may caused these symptoms, therefore the importance of going to a doctor if you feel any of these symptoms, because only an expert like him can make a correct diagnosis.

Mesothelioma cancer rate has increased over the past 20 years and although this disease is not as common as other cancer pathologies, the number of new diagnosed cases in the United States has risen up to 2,000 per year.

According to experts the major risk factor for developing Mesothelioma lies in working with asbestos, so if you are a asbestos worker remember following the U.S. Occupational Safety and Health Administration recommendations in order to reduce your risk.

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.
