Mesothelioma, A Rare Lung Cancer

Mesothelioma, A Rare Lung Cancer

Mesothelioma is a cancer of the mesothelium-the sac lining the internal body cavities. The lining around the lungs is called the pleural and in the abdomen it is known as the peritoneum.Although sometimes referred to as “asbestos lung cancer”, mesothelioma is not the same as lung cancer. Lung cancers occur inside the lung itself; mesothelioma occurs in the lining of the lung. Mesothelioma is rare, striking fewer than 3000 Americans per year.About 2000 people in the UK are diagnosed with mesothelioma each year.

There are three recognized types of mesothelioma.

1.Pleural mesothelioma

2.Peritonial mesothelioma

3.Pericardial mesothelioma

Pleural mesothelioma is the most common form of the disease, accounting for roughly 70% of cases, and occurs in the lining of the lung known as the pleura. Peritoneal mesothelioma occurs in the lining of the abdominal cavity, known as the peritoneum and pericardial mesothelioma originates in the pericardium, which lines the heart.

Asbestos is the most common cause of mesothelioma. Up to nine out of ten cases of mesothelioma are caused by exposure to asbestos. Asbestos is a natural mineral, mined from rock found in many countries. It is made up of tiny fibres that are as strong as steel but can be woven like cotton and are highly resistant to heat and chemicals.
During the 1960s the first definite link between mesothelioma and asbestos was made. In the past asbestos was imported to the UK in large quantities. It was used in construction, ship-building and in household appliances. Asbestos was very widely used in insulation materials, such as amosite insulation board, and building materials, including asbestos cement.
When asbestos is disturbed or damaged, it releases tiny fibres that can be breathed into the lungs. Asbestos fibres are very fine and, when breathed in, they can make their way into the smallest airways of the lung, so they cannot be breathed or coughed out. Once the fibres are in the lungs, the body’s defense mechanism tries to break them down and remove them, which leads to inflammation in the lung tissue.
The asbestos fibres can also penetrate through the lung tissue to settle in the pleura (the membrane around the lung). Over many years they can cause mesothelioma or other lung diseases to develop.

The History of the Asbestos Industry

The History of the Asbestos Industry

It was the Greeks who named this mineral asbestos, meaning inextinguishable. The ancient Greeks observed the harmful biological effects but continued to use the mineral said to have magical properties. Pliny (Roman naturalist) and Strabo (Greek geographer) noted an appearance of “sickness of the lungs” in slaves who wove asbestos into cloth. The Greeks also used asbestos for the wicks of the eternal flames of the vestal virgins, as the funeral dress worn by kings and for napkins. They were so impressed with the magical properties of the mineral that they were willing to overlook its harmful symptoms for humans. They went as far as calling asbestos “amiantus”, meaning “unpolluted.

During the middle ages, it was believed that the Frankish king, Charlemagne had asbestos tablecloths. Asbestos products were used in the 1700 hundreds but did not really become popular until the late 1800′s. The industrial Revolution demanded new uses for the mineral. It was used as insulation for steam pipes, turbines, boilers, kilns, ovens, and other high-temperature products.

The history of asbestos use continued into the twentieth century and researchers began to investigate the harmful toxic affects. It was first noticed in 1917 and 1918 that a great number of young people in asbestos mining towns prematurely died. Researchers in England carried out clinical studies on asbestos workers in 1924, after the recorded death of a young woman who had been diagnosed with the new disease they called asbestosis. Twenty-five percent of the test subjects showed evidence of asbestos-related lung disease. Legislation was enacted in 1931, to increase ventilation and to recognize asbestosis a work-related disease.

The 1930′s brought in with it, the surge of major medical research articles, warning about the asbestos connection with lung cancer partially due to a new disease, silicosis, caused by in haling silica dust particles. Much of this research continued to be ignored. Large Asbestos companies continued to use asbestos in manufacturing and construction, despite that fact that safer alternatives such as fiberglass insulation were created to replace it. These companies hid their lung cancer findings to avoid the million dollar lawsuits brought upon them by asbestos cancer victims. The history of asbestos use and company profiteering has no doubt exploited asbestos workers then and now. Today, victims exposed to asbestos are faced with mesothelioma cancer and certain death.

What is Asbestos?
Asbestos is a naturally occurring mineral fiber mined from the earth. It is strong, flexible, and resistant to heat, chemicals and electrical conditions.

Forms of Asbestos
The three most common forms of asbestos are divided into two groups. The serpentine group includes white (chrysotile) asbestos. The amphibole group includes brown (amosite) and blue (crocidolite) asbestos.

Asbestos Properties
Asbestos has many properties that once made it attractive to industry. It is stable when heated, it provides strength under tension, it is resistant to chemicals and does not absorb water (depending on type of asbestos). Asbestos is suitable for weaving and can be used to reinforce materials such as concrete. And lastly, it is a good resistance to electricity.

Asbestos Categories
‘Bonded’ is used to refer to asbestos being so firmly embedded in a material that these materials are unlikely to release measurable levels of asbestos fiber into the air if they are left undisturbed. Therefore, they generally pose a lower risk to health.

Bonded asbestos-containing materials include asbestos cement products (flat and corrugated sheeting used in walls, ceilings and roofs, molded items such as down pipes), vinyl floor coverings.

‘Friable’ is used to refer to asbestos-containing materials that can be easily reduced to powder by hand, when dry. These materials are more likely to release measurable levels of asbestos into the air when disturbed, and generally pose a greater risk to health. Friable asbestos-containing materials include sprayed asbestos fire retardants

Asbestos Industry
In the past, the asbestos industry used around 3000 products manufactured worldwide, most commonly in the construction, car manufacturing and textile industries. It was generally manufactured in the following forms: fibrous (limpet asbestos), woven (cloth, tape or sleeving), wound (rope) or mixed with a binder, such as calcium silicate (to make asbestos cement or vinyl floor products containing asbestos).

Because of its strength and its ability to resist heat and chemicals, asbestos was used in a range of insulation materials.
Older commercial industrial buildings and private dwellings may contain a variety of asbestos products, such as asbestos-cement sheeting in walls and ceilings, or roof cladding made from corrugated asbestos-cement. Asbestos may be found in structures built as late as the mid- to late 1980s.

Asbestos Related Occupations
Asbestos has been used in association with a number of occupations such as the US military and armed forces, particularly the Navy. Massive amounts of asbestos were used in shipbuilding and commercial construction prior to the mid-1970′s.

Other workers in occupations which have been associated with asbestos use are:

Insulators, Pipe Fitters, Plumbers, Electricians, Painters, Crane Operators, Floor Coverers, Pot Tenders, Welders, Paper Mill Workers, Custodians, Steam Fitters, Tile Setters, Aerospace Workers, Mechanics, Building Engineers, Demolition Crews, Former US Navy Personnel, Packing/Gasket Manufacturing Workers, Protective Clothing Manufacturing, Rubber Workers, Warehouse Workers, Home Improvement, Hospitals, Schools, Loading Docks, Glass Factory Workers, Building Inspectors, Bulldozer Operators, Manufacturing Workers, Excavating machine operators, Heavy Equipment Mechanics, Job and Die setters, Contractors, Building Managers, Mixing Operatives, Laborers, Sawyers, Teachers, Tinsmiths, Weavers, Excavators, Technicians

Risks of Asbestos Exposure
Humans come into contact with asbestos when they swallow or inhale the fibers. These particles can then become embedded in the tissues of the respiratory or digestive systems.

Three Main Diseases Caused by Asbestos Exposure

Asbestosis
Asbestosis causes widespread scar tissue between the alveoli, or spread over the lung. It is difficult to distinguish from other causes of interstitial fibrosis. Only confirmation of exposure to asbestos or detection of unusually high numbers of asbestos fibers in the lung is considered conclusive evidence of this disease.

Mesothelioma
Mesothelioma is a tumor of the chest lining, abdominal lining and occasionally the heart lining. Asbestos is not the only cause of this disease, but it is the most important cause in modern times. Crocidolite is the most important asbestos-related factor, but amosite, chrysotile and tremolite are also linked. This disease takes 20-50 years to appear, with the highest risk around 30-35 years after exposure. It is typically dose-related, but in rare cases has been known to occur in patients with little known occupational exposure to asbestos.

Lung Cancer
Lung cancer is relatively common among the general public and is the cancer most frequently associated with asbestos. Tumors grow and eventually obstruct airways. No characteristics specify a lung cancer as being caused by asbestos; we cannot distinguish a ‘cigarette’ lung cancer from an ‘asbestos’ lung cancer or ‘another’ lung cancer. Smoking increases the risk of death due to lung cancer for asbestos workers.

The history of asbestos and how it is has endangered human mortality has plagued different societies since ancient times. Throughout history must of these warnings have been ignored. Today, the use of asbestos is banned in the US and many other countries. This ban applies to manufacture, supply, storage, sale, use, reuse, installation and replacement of asbestos, except in special circumstances (e.g. removal and disposal of asbestos, and research work).

Mesothelioma is a form of cancer often exposed to asbestos. If you are worried that in the past may have been exposed, of course, you should see a doctor to get checked out. Besides this, you might also wonder which characters should be careful because, as a matter of course.

- Asbestos lung mesothelioma

The first figure out what to charge, mesothelioma is a very unusual form of cancer. This uniqueness is what makes it deadly. The problem is time. ItMesothelioma takes decades show no symptoms. They may appear in 15 years, or may be in the 45th As a result, look out for signs of a very disciplined approach requires that one not to fall over time.

Assuming you stick with it, what can be watching? Well, it’s a bit ‘of a trick question, Because mesothelioma is a type of cancer, but can appear in different parts of the body. The parties are usually the upper chest, mid chestand abdomen. Everyone has different symptoms, but the attack on the breast and especially the lungs are the most common. In such a situation, the symptoms are shortness of breath, cough, coughing blood, wheezing, abdominal pain, swelling, difficulty breathing and changes in bowel movements.

This isMesothelioma is one of the reasons so hard to diagnose if a doctor performed alone or a. The symptoms are often diagnosed as something other than this form of cancer. In fact, many studies consider that asbestos related deaths per year, more than reported because doctors do not recognize many of mesothelioma due to lack of training

Lung Cancer Treatment Options: Beating Lung Cancer

Lung Cancer Treatment Options: Beating Lung Cancer

True to most cases the treatment of cancer depends on many factors. Once a lung cancer has been staged, the physician and the patient can discuss with each other now treatment options that will be necessary. The patient should be well informed about the side effects and possible outcomes of a particular procedure.

- Asbestos lung mesothelioma

Everything should be resolved in order to avoid unpleasant. Other factors taken into consideration the general health of patients, medical problems, Treatment (eg chemotherapy) affect, and characteristics of the tumor.

The characteristics of lung tumors helps doctors to separate patients into two groups: those with low risk of cancer recurrence and those with high risk of recurrence of cancer.

Surgical resection is done with the lung cancer patients whose cancer has not spread beyond. This is done by the following: thoracotomy – opening of the chest for surgical procedures – and medianSternotomy – surgery performed by cutting through the sternum.

- Asbestos lung mesothelioma

Other approaches are limited front thoractomy (ALT) conducted thoractomy head on his chest with a small incision; anterioraxillary thoracotomy (AAT), thoracotomy performed in the chest near the shoulder front and posterolateral thoracotomy (PLT) thoracotomy at the bottom / side torso area. ALT, in particular, is less invasive than standard thoractomy – that is, less interferencethe body through cuts or other drastic measures. ALT may result in less surgical blood loss, less postoperative drainage, and less postoperative pain of thoracotomy standards.

recently made in other, less invasive procedures for the removal of tumors. For example, the video-assisted thoracoscopy (VAT), or as video-assisted thoracic surgery (VATS) is unknown. This method uses a camera to help introduce and operate on the lung in the chest area. The surgical incisions are made during the sales than for small thoracotomy or sternotomy is required.
