Mesothelioma Effects on the Body Cavity

The mesothelium is a membrane that covers the abdominal cavity, the chest cavity, and the heart. It is made up of cells that also cover just about all of the human internal organs. It also produces fluids that are vital for the organs to function properly. For example, the mesothelium provides the lungs the fluid they need to properly expand for breathing. Along with providing the fluid for the lungs to expand and contract, the mesothelium also will provide the fluid for the intestines to move freely for proper digestion and the heart will move freely to contract. The mesothelium that covers the lungs is called the pleura, the mesothelium around the heart is called the pericardium, and the mesothelium that covers the abdomen is the peritoneum. Each of these vital organs must have the vital fluids that are provided by it to function.Mesothelioma is cancer of the mesothelium. The mesothelium is made up of two layers and this cancer starts in the middle of these two layers. When mesothelioma is diagnosed it greatly affects the proper functions of the mesothelium. The body cavities will slowly stop functioning. When mesothelioma occurs the cells of the mesothelium start dividing. When the cells start dividing, they divide uncontrollably and abnormally. This cell division can damage other organs that are near by. And without treatment it can spread fast and go to the main organs in your body.Symptoms occur when tumors start to get larger and fluid starts to fill up the mesothelium walls. Mesothelioma is a form of cancer that greatly endangers the human body cavity. Mesothelioma is a fairly new discovery and research is being done daily to get more treatment options for this cancer. It is hard to diagnose this vicious cancer because it is so uncommon and many of the symptoms can be read as the same as many other illnesses.

An Introduction to Mesothelioma

Mesothelioma is a rare, highly aggressive cancer of the mesothelium, which is a thin tissue lining covering the thoractic cavity (the pleura), the heart sac (the pericardium) and the abdominal cavity (the peritoneum). The function of the mesothelium is to support, protect and lubricate organs and body cavities.There is concrete evidence linking the principal cause of mesothelioma to asbestos exposure. Indeed, between 70-80 percent of all mesothelioma cases are linked to excessive exposure to asbestos at work. Thus, it is typically classified as an “Industrial Disease”. Asbestos is a natural, fibrous mineral with exceptional fire-retardant properties, which led to its widespread use in fireproofing buildings.Unknown at the time of Asbestos’ introduction to building materials, when disturbed or damaged, asbestos fibres are released, easily inhaled and can become permanently lodged in the lungs. Millions of people have been exposed to asbestos, meaning that the next decade at least will surely see continuing mesothelioma diagnoses. According to The Finnish Institute of Occupational Health, mesothelioma in Western Europe is expected to peak between 2010 and 2020. This is due to mesothelioma taking between 20 and 30 years to develop.The two main types of mesothelioma diagnoses are for pleural (thorax) and peritoneal (abdominal) mesothelioma. The symptoms of pleural mesothelioma include: pain in the lower back or the side of the chest, persistent coughing, developing a husky voice, weight loss and shortness of breath. Symptoms of peritoneal mesothelioma include: abdominal pain and swelling, diarrhoea or constipation, poor appetite and sickness. The problem is that these symptoms can be applied to many different illnesses, but it are particularly important to consider if the person developing symptoms has a history of absestos exposure.Asbestos was banned in the United Kingdom in 1999, with several lobbying organisations working towards a worldwide ban. Typically, high risk professions include: metal plate workers, vehicle body builders, carpenters, plasterers, construction workers and other construction trade-based professions. Tony Whitston of Greater Manchester’s Asbestos Support Group has said: “Many believe that asbestos is a problem which was faced by shipyard workers and laggers decades ago. But asbestos is still a danger for our tradesmen today. [...] If we do not act now a whole new generation of people will develop mesothelioma in 30 years time.”Unfortunately, mesothelioma is typically diagnosed when the disease is in the advanced stages, due to a lack of symptoms, people don’t go to the doctors early on. This is one of the main reasons why patients diagnosed with the cancer are often told they only have a year to live. According to Cancer Research, 10% of diagnosed patients will be alive three years later, going down to 5% survival rate after 5 years.Surgery will not cure mesothelioma, but can help control the disease and keep the victim healthy for as long as possible. Like most cancers, radiotherapy and chemotherapy are often used in conjunction with fluid drainage (Palliative Care) programmes. Even major surgery involving removing entire lungs and the surrounding mesothelial layers cannot cure the disease. Whilst mesothelioma is terminal, many victims choose to seek action against their employers for negligence and seek to make a mesothelioma claim. This is usually successful if the victim was owed a duty of care, there was a breach of duty or workplace exposure to asbestos can be directly attributed to causing mesothelioma.

We all heard of Absestos and the horrible consequences it has in our health. Asbestosis is “a form of lung disease (pneumoconiosis)” which causes interstitial fibrosis or scarring of the lungs.Asbestosis is progressive and, for the most part, irreversible. Respiratory impairment worsens with time, even if exposure to asbestos has ceased. Asbestosis is usually found in asbestos workers and not in the general public. People with asbestosis have shortness of breath, often along with a cough. Asbestos cretes Mesothelioma, and Mesothelioma is a form of cancer which affects mesothelial tissue in the lungs, peritoneum or pericardium. The biggest concern mesothelioma is that can arise both from visceral and parietal peritoneum. It is diagnosed in advanced stages in most cases, and it often takes considerable time to arrive at the correct diagnosis, as the mean symptoms-to-diagnosis time reported is 122 days. The most frequently reported initial symptoms are abdominal pain (35%), abdominal swelling (31%), anorexia, marked weight loss, and ascites ; less frequently night sweats and hypercoagulability. Clinical presentation with fever of unknown origin, intestinal obstruction, or surgical emergency (due to acute inflammatory lesions) have been reported. Mesothelioma (cancer of the mesothelium) is a disease in which cells of the mesothelium become abnormal and divide without control or order. They can invade and damage nearby tissues and organs. Mesothelioma is defined as an ICD-O histology code of 9050-9053. Data are presented for a five-year time period. Mesothelioma cell viability was decreased in a dose-dependent manner by lovastatin (5 to 30 microM). These effects were not reversed by exogenous growth factors or cholesterol, but were reversed by addition of doses of micro mevalonate, confirming that lovastatin affected mesothelioma viability by inhibiting mevalonate synthesis. This is based on the fact that Mesothelioma is a cancer of the thin lining surrounding the lung. That %26#39;s whythis disease is almost always fatal, often within a few months of diagnosis.The scary part about this ilness: is that mesothelioma has a much longer latency period compared with lung cancer (40 years versus 15-20 years). Understanding this, mesothelioma is therefore likely to be found among workers who were first exposed to asbestos at an early age. Mesothelioma is always fatal. Mesothelioma has also been found in individuals who were exposed to asbestos only once decades earlier. The only known cause of mesothelioma is asbestos. As we mentioned before, mesothelioma has a much longer latency period compared with lung cancer (40 years versus 15-20 years), and that is why mesothelioma is always fatal. Once you found out that you have mesothelioma, it is usually to late.Exposure to asbestos has also been associated with an increased incidence of esophageal, kidney, laryngeal, pharyngeal, and buccal cavity cancers. As with other known chronic occupational diseases, disease associated with asbestos generally appears about twenty years following the first occurrence of exposure: There are no known acute effects associated with exposure to asbestos. Exposure to ozone for several hours, at relatively low concentrations, has been found to significantly reduce lung function. Also this sort of exposure induce respiratory inflammation in normal, healthy people during exercise. This decrease in lung function generally is accompanied by symptoms including chest pain, coughing, sneezing, and pulmonary congestion. Also it is vital to remind readers, that exposure to environmental tobacco smoke (ETS) is a significant cause of lung cancers in people who themselves do not use tobacco. Let %26#39;s don’t forget that between 3000 and 6000 lung cancer deaths per year in the United States are caused by exposure to ETS.

Mesothelioma is a cancer that typically presents itself in malignant form and results in tumors in and around vital organs of the body. The actual medical definition of “mesothelioma” is “cancer of the mesothelium.” The mesothelium is the sac that lines and protects vital organs such as the heart and lungs. Mesothelioma is the result of exposure to asbestos and typically comes in three forms: pleural mesothelioma, peritoneal mesothelioma, and pericardial mesothelioma. Tragically, the symptoms of all types of mesothelioma do not manifest until several years, even decades, after exposure to asbestos. This makes the disease difficult to diagnose, and often, it’s too late to treat the patient once the diagnosis is made.

Pleural Mesothelioma

This is the most common form of the disease; this occurs when the cancer affects the lungs and protective lining and cavity of the lungs. Sufferers may experience difficulty breathing, difficulty swallowing, shortness of breath, persistent coughing, weight loss, fever, coughing up blood and rasping.

Peritoneal Mesothelioma

A rarer form of mesothelioma is peritoneal mesothelioma. This is where the cancer affects the stomach and abdomen. The cancer can start in the abdominal area and spread to other parts of the body, but the tumours that press against the wall of the abdomen can cause some or all of the following symptoms: abdominal pain, abdominal swelling, nausea, loss of appetite, vomiting, breathing problems, chest pain, bowel obstruction, anaemia, fever, and blood clotting abnormalities.

Pericardial Mesothelioma

This is the rarest form of the disease and is where the cancer affects the heart and the cavity that surrounds the heart. The tumors affecting sufferers of this type can cause chest pain, shortness of breath, difficulty breathing, persistent coughing, and heart palpitations.

Other asbestos-related illness

There are also cases of other asbestos related diseases such as asbestosis and respiratory problems that have stemmed from exposure to this potentially fatal material. Anyone that has worked with asbestos should see their doctor if they have any onset of this type of problem or if they are concerned and have doubts.

I decided to create this article for all the people out there, spending all day searching the keywords “what is mesothelioma and what problems does mesothelioma cause” on Google.

Many of us still do not know what is mesothelioma cancer or disease? Well this article will tell you more or less some of the information about Mesothelioma cancer or disease.

Mesothelium covers the external surfaces of the heart and lung. It also covers the inner surface of the chest wall and the inner surface of the sac that surrounds the heart called pericardium. In the lungs the mesothelium is called pleura, in the heart it is called pericardium, and in the abdominal cavity it takes the name of peritoneum.

Its primary role is to protect these organs by producing a lubricating fluid that allows for movement. While mesothelioma can affect any of the mesothelial tissue in the body, it is most commonly seen in the pleural or peritoneal mesothelium. Sadly, many patients are not diagnosed with mesothelioma until symptoms are present, and symptoms are not usually present until the cancer is in its advanced stages.

To understand this a little better, let’s clarify that the mesothelium is a membrane that covers and protects most of the internal organs of the body. It is composed of two layers of cells: One layer immediately surrounds the organ; the other forms a sac around it. It (cancer of the mesothelium) is a disease in the cells of the mesothelium, which become abnormal and divide without any control and order. They can invade and damage nearby tissues and organs. Mesothelioma (cancer of the mesothelium) occurs when the cells of the mesothelium become abnormal and divide without control or order. Nearby tissues and organ can be affected and the cancer cells can also metastasize (spread) from their original site to other parts of the body.

So what is Asbestos? Well, asbestos fibers cause lesions and scarring on the mesothelium, ultimately leading to the formation of tumors. The damaged cells secrete large amounts of a clear fluid that presses on the lungs and other organs, causing severe discomfort. The tissue formed by these cells is called mesothelium.There are three main types of malignant mesothelioma: epithelial, sarcomatoid and mixed. The epithelial type is the most common. Mesothelioma is a horrific disease where a particular type of cell (the mesothelium) divides without control. This division of cells can lead to mesothelioma.

Now, not everything is bad news. Benign mesothelioma may occur wherever there is mesothelium. It is localized and does not spread to nearby tissues. Cancer that occurs in the mesothelium tissue is called mesothelioma . Malignant cells develop in the mesothelium, a protective lining that covers most of the body’s internal organs. The most common site is the pleura (outer lining of the lungs and chest cavity), but mesothelioma may also occur in the peritoneum or the pericardium .

One of the ongoing problems, however, with this remedy is the fact that mesothelium cancer can take years before it starts to show. In some cases, this period has been over 40 years. The mesothelium makes fluid between the two layers that lubricates the movement of the organs it protects. It actually develops in the mesothelium; a thin, double-layered protective sheath that surrounds vital organs and body cavities.

The mesothelium that protects the chest and lungs is called the pleura and the mesothelium that surrounds the abdomen is called the peritoneum.

Mesothelioma is a form of lung cancer, predominantly caused by exposure to asbestos fibers. In fact, mesothelioma is a cancer of the mesothelium, the sheath that covers major organs such as the lungs (pleurum), the heart (pericardium) and the abdominal cavity (peritoneum). Pleural mesothelioma is by far the most common kind.

Mesothelioma and Asbestos

When asbestos fibers are inhaled, they become embedded in the lining of the lungs. Due to their small needle-like size, the normal defenses of the body are unable to detect them. Usually, any foreign bodies such as this would either be coughed up, or be removed through a build-up of mucus around them. But nor asbestos. They cause inflammation of the lungs and tissue damage, leading to scarring and coughing. These are the initial symptoms of asbestosis, though asbestosis is not mesothelioma.

No one knows for sure why cancers develop, but once cancerous cells are formed in the pleura, it gradually becomes thicker, and over time restricts breathing and causes shortness of breath and coughing. What is known as ‘pleural effusion’ occurs, as the fluid of the pleura, designed to lubricate the movement of the lungs against the other organs nearby, builds up and exerts pressure on the lungs. The thickening of the pleura continues as an increasing number of cells become cancerous, until death eventually occurs.

The Effect of Smoking

Although smoking is known to lead to a number of forms of cancer, it does not in itself promote mesothelioma. However, a patient that has been exposed to asbestos, and who also smokes, will be more liable to contract the disease than a non-smoker will. This is why smokers are generally awarded lower sums in compensation than non-smokers with the same condition. However, it would be wrong to state that smoking is a cause of mesothelioma.

It is, however, the cause of many more lung cancer cases than mesothelioma caused by asbestos, and smoking and asbestos together also increase the risk of the patient developing general lung cancer, just as prolonged exposure to asbestos causes more than just mesothelioma. Asbestos lung cancer and mesothelioma are not the same thing.

Symptoms

The major symptoms are shortness of breath, weight loss, nausea and pain. This is true of all forms of mesothelioma, not only pleural mesothelioma. In the case of peritoneal mesothelioma, the abdomen becomes very painful and distended, just as the pleural version causes tightening and swelling in the chest due to pleural effusion. The pressure created can also result in pain, apart from that of the cancer itself.

Diagnosis

If the disease is not diagnosed early, then survival is unlikely. Therefore, any person who has previously worked in the asbestos industry, or has used asbestos in their employment, should make their doctor aware of that fact. They can then be placed on a schedule of regular examinations designed to detect the first signs of the disease. If the condition is detected early enough, most treatments available can be used effectively, and surgery is much more likely to be effective if the area affected is able to be isolated.

If you have contracted the disease, stopping smoking is essential, and you must try to avoid all infections of the lungs and airways. It is possible to have the condition treated, but if diagnosed too late then treatment tends to be palliative, and designed to make the patient as comfortable as possible.

It is essential, therefore, that people that have a history of contact with asbestos inform their physician immediately to make sure that if the symptoms do occur, they are spotted before any lasting harm can be done. Only then will there be a hope of a cure and successful recovery from this insidious disease.

Pleural Mesothelioma is the most prevalent form of the various aggressive lung cancers and this cancer invades the lung cavities. ‘Pleura’ is the sac that houses the lungs within a thin membrane called mesothelium. This mesothelium secretes fluid and assists the lungs to contract and expand during breathing. Pleural mesothelioma is the %26lt;a href=”http://mesotheliomastraight.net/asbestos”%26gt;cancer of the mesothelium%26lt;/a%26gt; of the lung cavities and it is associated with individuals who live in surroundings where asbestos-related dust is major air pollutant. Prolonged inhalation of the air-borne asbestos-related particles leads to inflammation of the lungs and eventually the asbestos particles and fibers get settled on the lung surfaces and thereby making the tissues carcinogenic. The cancer cells remains dormant for long, but symptoms slowly begin with a normal chest pain coupled with some warning signals such as: * Difficulty in breathing and shortness of breath * Loss of appetite and weight loss * Excessive coughing and wheezing * Tendency to vomit often Tests and Diagnoses: It is extremely difficult to diagnose pleural mesothelioma as it is often confused with common illnesses as cold and/or flu, whooping cough or pneumonia due to almost similar symptoms. However, thanks to many diagnostic procedures the disease can be confirmed. Chest x-ray and MRI: These are painless imaging studies and along with CT scan and ultrasound the radiologist gets a detailed picture of the lungs that reveal pleural effusion. Biopsy: A radiological scan is followed by a needle biopsy (also called an aspiration biopsy) to confirm the cancer cells by taking out fluid from the lungs. It is then a pleuroscopy and thoracotomy done to confirm the presence of pleural mesothelioma. %26lt;a href=”http://mesotheliomastraight.net/asbestos”%26gt;Treatment Methods:%26lt;/a%26gt; Complete cure for this silent killer disease is still a far cry. An expert treats with multi-modality approach and it is most likely to be a palliative form of treatment. The approach includes combination of surgery, radiation, photodynamic therapy and systemic chemotherapy with cancer drugs (often times Cisplatin and gemcitabine). Some of the advancements in the field of pleural mesothelioma therapy include: Administering pemetrexed, an antimetabolite along with Cisplatin and this adjuvant therapy is found to give a higher survival rate than using Cisplatin alone. Using the dynamics of light is also used as a principle to kill carcinogenic cells. However, this can be a method when mesothelioma is in the early stages. Immunotherapy is another approach that aims to enhance the body immune system but as of now still being researched to use as an alternative to treat a pleural mesothelioma patient. Brachytherapy is another newborn approach, and it is a kind of radiation therapy applied from within the body as opposed to application from outside. This helps to prevent damage of healthy cells due to exposure to high radiation.
