Chemotherapy and Radiotherapy

The treatment of mesothelioma, depends on a number of things, including mesothelioma, as the disease is advanced, the overall health and fitness of patients and their personal preferences.

There are various treatments that can be recommended for mesothelioma. Among active symptoms, radiotherapy, chemotherapy and surgery. A patient can only make this type of treatment, or a combination of them. Radiotherapy and chemotherapy are treatments, which can be used for the treatment of symptoms of mesothelioma. Radiotherapy is, in general, in a manner aimed at preventing the spread of mesothelioma in the scars or biopsy.

Radiotherapy & Mesothelioma

Radiotherapy is the use of high radiation to kill cancer cells in the body. All cells in the treated part of the body, which have the potential of radiotherapy. Normal, healthy cells is to a certain degree rest. Radiation is used for the treatment of a certain sector of isolation of the body (for example, an area in the chest, which felt the pain). The processing sector is often seen as a field of radiotherapy.

A course of treatment is individual. The course can also be of several doses, which, as a general rule, in groups, or just a few. The number of fractions required would be necessary, it all depends on the height of the fabric, which is treated. Treatment of radiotherapy, it is not usual on the weekend. Radiotherapy mesothelioma may, in reducing the size of the tumor to help alleviate symptoms, such as pain or discomfort.

Radiation can also be applied to the scar left by a biopsy, or surgical drainage. This is designed to prevent the spread of mesothelioma in the page as perhaps microscopic deposits occurred in the loading and removing pipe, biopsy needles or surgical instruments. In mesothelioma radiotherapy may also carry out large areas. Any chest on top of the patients can be treated after surgery to kill diseased cells, it has not been possible during the operation to remove. (Please note that the surgery section for details about the surgery and mesothelioma). In small scars mesothelioma often with three doses (groups), radiation. When considering aimed at relieving symptoms such as pain up to 10 doses (groups) is needed. If after the operation, in a large area up to 30 treatments may be necessary.

Staging of Mesothelioma

When the diagnosis of cancer, it is necessary to know what kind of cancer (eg mesothelioma), but also the extent (stadium) of the disease. The stage describes the position and size of the cancer, and if yes or no there is evidence that it is only in the vicinity of tissues or other, more distant sites. The staging can be useful in assessing the prognosis, in the formulation of recommendations for the treatment and evaluation and comparison of the results of treatment. There are various systems required for the staging of mesothelioma. Here is an abbreviated version of the International Mesothelioma Interest Group (IMIG) staging system, the most widely used:
-Stage 1 disease located on the pleura only on one side of the chest.
-Stage 2 disease on the pleura on one side of the chest, but the cancer cells have long pleura in lung tissue or underlying muscle of the diaphragm.
-Stage 3, the cancer has also promoted the pleura glands in the chest and / or increased deeper into the tissue around the pleura.
-Stage 4 cancer has widely spread to organs or tissues or far penetrated deep into the tissue near the pleura eg through the aperture in the abdomen, as opposed to the pleura in the lung or the spinal column or the muscles of the heart. To the staging of the extent of the disease in general, the computer can be carried out and all that is required. Further analysis is sometimes used in some centers on the inclusion of MRI imaging (MRI), ultrasound scan (SGB) and the Tomography by the issuance of positron emission tomography (PET) scans.

Diagnose of Mesothelioma

Mesothelioma is a form of cancer affecting the mesothelium, which is a thin membrane that lines the inner surface of the chest wall, where he is known as the chest and abdomen, where it is known as the peritonitis. It also surrounds the organs within these cavities such as the heart, lungs and intestines. It is much more common in the chest mesothelioma than in the abdomen.

It is about a case of peritoneal mesothelioma for every 12 cases of pleural mesothelioma.

Mesothelioma is not an easy disease to diagnose. Often a series of tests and hospital visits, and even then it is not always possible, that mesothelioma.

Symptoms & Referral

The first signs of the disease are rather vague. The most common symptoms are shortness of breath, chest pain, fatigue and weight loss. In most cases, the first sign of something wrong is when shortness of breath or chest pain occurs as a result of effusion. This is when fluid accumulates in space (pleural cavity) between the two layers of the pleural lining. At this stage, the patient is often visit their physician.

The GP often arrange a chest X-ray. However, the signs of mesothelioma on a chest X-ray is often unclear and X-rays can show thickening of the pleura or an accumulation of fluid in the pleural space, which can also be caused by other conditions . Depending on the outcome of the X-ray, the doctor can take emergency patients to a hospital consultant specializing in lung cancer and mesothelioma.

Asbestos Removal

Generally, asbestos is a risk that if you disturb or damage the fibers and cause to be released into the air. If asbestos-containing materials are in good condition and in a position where they will not be disturbed or damaged, it may be safer to leave them where they are and make sure that all the risks are properly managed. Professional advice should be sought.

Asbestos has been used in many different products and buildings from the 1950s until the mid-1980s. Many homes can contain asbestos-containing materials. If you are concerned about asbestos at home, and the potential for the removal, you should contact the local council in your area. They will be able to provide professional advice.

The Couse of Mesothelioma

From all mesothelioma cases, asbestos is the most couse of mesothelioma.Asbestos is responsible for up to 9 out of 10 mesothelioma cases. There are thought to be other rare causes of the disease but none are fully understood at this time. The disease has been described in medical literature since 1870 although the first suspicion linking asbestos and mesothelioma did not appear in the U.K. until 1935 and a definite link was not reported until 1960.

Asbestos

Asbestos is a natural fibrous mineral that is widely distributed in nature. Its name derives from the Greek meaning ‘inextinguishable’, which suggests its ability to resist heat and fire have always been understood. It is the ability to resist heat and fire that resulted in asbestos being used widely in industry, shipbuilding and construction particularly during and after World War II. Currently the largest producers of asbestos are Russia, China and Canada. Russia and China use a majority within their own country however Canada dominates the export market. There are still over 100 countries producing asbestos containing pipes and sheets to be used as low cost building material.

There are three main types of asbestos, blue (crocidolite), brown (amosite) and white (Chrysotile). They are all harmful but blue and brown asbestos are recognised as the most hazardous and have not been imported into the UK since 1985. However, they are still present in buildings and equipment produced before the ban. White asbestos was only banned in the U.K. in 1999.

It is asbestos dust or airborne fibres, which cause harm when inhaled or ingested. Asbestos materials left undisturbed probably poses no significant threat. Asbestos fibres are very fine and if they are breathed in they can reach the smallest areas of the lung where they cannot be breathed or coughed out. Once they have lodged in the lung the body’s defence mechanism tries to break them down and remove them which leads to swelling and inflammation in the surrounding area. The fibres can also penetrate the edge of the lung and settle in the pleural lining. The fibres can also be swallowed and in a similar way can lodge in the abdomen and work their way to the peritoneum that lines the abdomen where the same swelling and inflammation can occur.

If you have been exposed to asbestos at any time you are potentially at risk although it should be made clear that the majority of people who have been exposed to asbestos dust do not suffer ill health as a result. There is no way of identifying who or why some people go on to suffer and others remain unaffected.

Mesothelioma

Mesothelioma is usually also known as ‘diffuse’ or ‘malignant’ mesothelioma. Mesothelioma is a form of cancer that affects the Mesothelium, which is a thin membrane that lines the inner surface of the chest wall where it is known as the pleura, and abdomen, where it is known as the peritoneum. It also surrounds the organs found within these cavities for example the heart, lung and intestines. It is far more common to have mesothelioma in the chest than in the abdomen, there is approximately 1 case of peritoneal mesothelioma to every 12 cases of pleural mesothelioma.

Symptom

It can take many years after being exposed to asbestos for mesothelioma to occur. The length of time taken is referred to as the latency period and is usually between 15-45 years.In the early stages when the mesothelioma is present as small lumps it will not show up on any scans or x-rays and is unlikely to cause any symptoms. As it progresses pleural and peritoneal mesothelioma can both cause general symptoms such as sweating, tiredness, loss of appetite and weight loss. As the disease advances pleural mesothelioma typically causes patients to feel breathless and/or experience chest pain.

Breathlessness may be due to a combination of factors. The pleura being thickened can act like a rind around the lung restricting its movement and preventing the lung from expanding.Pain can be quite severe as the mesothelioma can extend into the tissues surrounding the pleura including nerves and bone. A variety of medication is available to combat any pain experienced.
Fluid may also accumulate in the space between the two layers of the pleura occupying space and again this restricts lung expansion. A cough or altered voice is also sometimes experienced. Peritoneal mesothelioma often causes swelling and pain in the abdomen.

Two kind of Mesothelioma

1. Pleural Mesothelioma

The pleural lining has two layers: the visceral (inner) layer is next to the lung and the parietal (outer) layer lines the chest wall. The pleura produces fluid that lubricates the space between the two layers, this allows the two layers to slide comfortably over each other as we breathe in and out.

Pleural mesothelioma causes the pleura to thicken. This thickening of the pleura might begin to press onto the lungs or attach itself to the inside of the chest wall. In either case the expansion of the lung becomes progressively restricted by the tumour. Fluid, sometimes several litres, can collect between the two layers of the pleura; this affects the lungs ability to expand and causes the person to feel breathless. This is known as a pleural effusion.

2. Peritoneal Mesothelioma

The peritoneum also has two layers the inner (visceral) layer which is next to the abdominal organs and the outer (parietal) layer which lines the abdominal wall.

Peritoneal mesothelioma causes the peritoneum to thicken and fluid to collect in the abdomen. This collection of fluid is called ascites and causes the abdomen to swell. Because pleural mesothelioma is more common and often spreads to the peritoneal cavity, it is sometimes necessary to determine if pleural mesothelioma is the primary cancer.
