what is the cause of malignant mesothelioma

Mesothelioma, known more precisely, malignant mesothelioma is a rare cancer of the epithelial cells, most commonly those in the lining that covers the lungs (pleura). There epithelial cells in the lining (membrane) which covers the outer surface of the body organs. Suffered the majority of people with mesothelioma to asbestos at some time during their lives.

Doctors usually divide mesothelioma into three types:

Pleural mesothelioma - affects the pleura , the lining surrounding the lungs . This is the most common form .

Peritoneal mesothelioma - cancer attacks the lining of the abdomen and peritoneum. This is the second most common form .

Pericardial mesothelioma - cancer attacks the protective layer that covers the heart. This is the rarest form .

Is the cause of all three forms of mesothelioma is almost always by exposure to asbestos .

Mesothelioma is an aggressive form of cancer. For the majority of patients there is no cure . Doctors usually focuses on improving the quality of life with the progress of the disease - making the patient as comfortable as possible .

In the United Kingdom , and is diagnosed nearly 2,000 patients suffering from mesothelioma every year. According to the CDC ( Centers for Disease Control and Prevention ) , mesothelioma kills more than 2,700 people in the U.S. each year. According to the record of mesothelioma, and deaths from this type of cancer increased more than ten-fold 1969-2009 in the United Kingdom . About four -fifths of all deaths are among men .

According to the medical dictionary Medilexicon, and mesothelioma is:

"Consists rare tumor cells derived from the lining of the pleura or peritoneum , which also grows thick paper covering the viscera and spindle cells or fibrous tissue which may enclose spaces lined glandlike of by the cubic cells . "

What are the signs and symptoms of mesothelioma ?

Symptom is something the patient feels and describes , while a sign is something other people could see, including doctors and nurses. For example , it may be a symptom of pain , while the sign can be rash.

Exposure to asbestos and asbestos dust can take up to thirty years until symptoms appear . In many cases, patients are diagnosed when the disease is already advanced . Results are based on how early it can be diagnosed with a malignant tumor .

Signs and symptoms of mesothelioma vary, depending on where in the body the cancer is .

Pleural mesothelioma ( tissue surrounding the lungs)

Shortness of breath

Coughing, often painful

Unexpected loss and unexplained weight

 Pain under the rib cage

In some cases, you may be exposed lumps under the skin in the chest area

Lower back pain

Discomfort in the chest

Exhaustion

Some people may experience excessive sweating , fever , or difficulty in swallowing

Peritoneal mesothelioma ( abdominal lining )

Unexplained weight loss

Abdominal pain

 Swelling in the abdomen

 Lumps in the abdomen

Nausea, and some patients may experience vomiting

Pericardial mesothelioma ( in the region of the heart lining )

Low blood pressure

Shortness of breath

Fluid retention (edema ), often in the legs

Heart palpitations

Tiredness , extreme effort after the light

Chest pain

What are the causes of mesothelioma ?

Experts say that prolonged exposure to asbestos particles is the main cause of mesothelioma. Risk associated with this disease closely to asbestos particles dose - any possibility of developing mesothelioma is directly proportional to the length of time a person is exposed , and the amount inhaled.

People in jobs where exposure to asbestos fibers common to have a higher risk of developing the disease. Asbestos was commonly used for insulation, soundproofing , fire, and ceilings, and ironing board covers .

Mesothelioma in the chest ( pleural mesothelioma )

Begins with pleural mesothelioma in the pleura . Pleura is two layers of the thin membrane that surrounds the lungs and chest wall line . The inner layer is attached to the lungs and lines the outer layer of the chest wall and diaphragm. Between the two layers is the pleural cavity . This is almost empty cavity . Two layers of the pleura slide against each other. They are moist so that it can move smoothly lungs against the chest wall during breathing.

treatment of lung cancer

 Lung Cancer:

A Lung cancer, the leading cause of death that you get as a result of cancer, whether between men or between women. And sign a number of lung cancer victims annually, far greater than  colon cancer , prostate cancer , cancer of the lymph nodes and breast cancer together.

However, you can prevent most deaths from lung cancer, because smoking is responsible for nearly 90 per cent of all cases of lung cancer. And the proportion of lung cancer risk increases exponentially depending on the year and the number of cigarettes smoked.

To quit smoking , even after smoking for many years and many, can reduce the risk of lung cancer, significantly. It can reduce the risk of lung cancer by avoiding exposure to other factors that cause lung cancer, such as exposure to asbestos (Asbestos), radon and secondhand smoke.

Symptoms of Lung Cancer

Symptoms of lung cancer does not appear in the early stages in most cases. And often show symptoms of lung cancer only when the disease has reached an advanced stage already.

The symptoms of lung cancer include the following:

    Newbie cough, appears and disappears
    Changes in the existing chronic cough or cough smokers
    Cough accompanied by bloody Mucus, even if it was a little too
    Shortness of breath
    Pain in the chest
    Whistling when breathing
    Hoarseness

Treatment of lung cancer

Decide tumors specialist (Oncologist), in consultation with the patient, the method and system of the treatment of lung cancer, depending on several factors, such as the general health status of the patient, the type and degree of cancer, taking into account the patient's personal choices.

Treatment options include, in general, treated one or more of: surgical treatment, chemotherapy, radiation therapy or drug treatment center.

    Surgery

In surgery the surgeon removes the fabric area where there are cancerous tumor, in addition to the margins of the healthy tissue surrounding it.

Surgery to remove lung cancer include:

    Amputated (cut) in the form of a wedge in order to take out the part that contains the cancerous tissue, along with a margin of healthy tissue surrounding the
    Amputated (cut) pulmonary lobe (Lobectomy) to remove the entire lobe of the lung
    Pneumonectomy (Pneumonectomy) to remove the entire lung

If you made such an operation, the surgeon also removes lymph nodes in the chest area, to check if they are also carries within tissue containing cancerous cells. And if it has already been found on the cancerous tissue, it is usually a sign that the cancer has spread and spread, even if it has yet to show any signs outside the chest.

    Chemical treatment (chemotherapy - Chemotherapy)
    Radiation therapy (radiotherapy - Radiotherapy)
    Intensive drug treatment

Intensive treatments are novel therapeutic methods work by focusing on pre-defined deviations get in cancer cells.

Drug treatment center options for lung cancer include:

 
Prevention of lung cancer

There is no foolproof method and confirmed for the prevention of lung cancer, but it can reduce the risk of developing lung cancer if it is Take the following measures:

    Avoid smoking
    Quit Smoking
    Avoid passive smoking
    Tests to detect the presence of radon gas in the vicinity of the house
    Avoid exposure to carcinogens at work
    Maintain a diet rich in vegetables and fruits
    Keep drinking alcohol in moderation, or avoided altogether

Alternative Therapies

The patient may resort lung cancer, or they may try to go, toward alternative medicine or complementary medicine , in search of a cure heal Ail lung cancer.

But one must be aware that alternative treatments for lung cancer is not supported by medical studies, and there is no evidence that these treatments are effective and efficient. Moreover, in most cases, do not know the side effects of these treatments, absolutely.

And alternative therapy for lung cancer can be costly and requires travel to distant places. Therefore, it is recommended to consider carefully and reflect on therapeutic options prior to their adoption.

what is asbestos disease

  What is asbestos?

Asbestos is a group of minerals that occur naturally as bundles of fibers . Found these fibers naturally in soil and rocks in many parts of the world. It is mainly made of silicon and oxygen , but also contain other elements. There are 2 main types of asbestos :
Chrysotile asbestos, also known as chrysotile asbestos , is the most common type of asbestos in industrial applications. When I looked under the microscope, and wrap the asbestos fiber chrysotile about the same as in a spiral , and this is why this form of asbestos has also been called asbestos serpentine or curly .


Amphibole asbestos fibers are straight and needle-like . There are several types of amphibole fibers , including in that amosite ( brown asbestos ) , crocidolite ( blue asbestos ), tremolite and actinolite , anthophyllite .
Both types of asbestos cause cancer . Amphibole asbestos does not seem to be much more effective in bringing about a rare type of cancer called mesothelioma

Asbestos fibers are strong and resistant to heat and many chemicals , and is not connected to electricity. As a result , asbestos was used as insulation material since ancient times. Since the industrial revolution , asbestos has been used to isolate factories, schools, houses , ships , and make cars brake and clutch parts , roofing shingles , ceiling tiles , cement , textiles and hundreds of other products.

During the first half of the 1900s, showed increasing evidence that breathing in asbestos cause scarring of the lungs . In the early 1900s , and it was exposure to asbestos dust in the workplace is controlled . Beginning in England in the 1930s , steps have been taken to protect workers in the asbestos industry by installing ventilation systems and exhaust. However , in an effort to build large ships during World War II , have been large numbers of workers to high levels of asbestos.

It has also become asbestos - related cancers recognized as the best in the second half of the 20th century , has taken measures to reduce exposure , including the development of radiation exposure standards and laws that prohibit the use of asbestos in building materials . There was a significant decline in the import and use of asbestos since the mid - 1970s , and we have been developing alternative insulation materials . As a result , decreased exposure to asbestos dramatically in the United States. However , it is still used in some products, it is still possible to be exposed to asbestos in the old buildings , and water pipes , and other places . Asbestos has been banned in the European Union for several years, although the ban does not require removal of asbestos that were already in place. However , there is still heavy asbestos use in some countries.

How can I avoid exposure to asbestos?

If there is a possibility you may be exposed to asbestos at work , such as during the restoration of old buildings , you must use all the protective equipment , work practices, and safety procedures are designed to work around asbestos. If you are concerned about exposure to asbestos in the workplace , discuss the situation with your employee health and safety representative or your employer . If necessary , the Occupational Safety and Health Administration ( OSHA ) , and the federal agency responsible for health and safety rules in most workplaces , and to provide more information or inspection procedure.

If you live in an old house , there may be asbestos-containing insulation or other materials. Knowledgeable expert can check your home to determine if there is any asbestos and if it poses no risk of exposure . This may involve testing the air for asbestos levels . (Again , just to asbestos exists in the home does not necessarily mean that it needs to be removed . As long as the material is damaged or disturbed, for example by drilling or remodeling , no release fibers into the air. ) If needed asbestos to be removed from your home , you should hire a qualified contractor to perform this task to avoid contaminating your home or causing any exposure for your family or for workers. You should not attempt to remove materials containing asbestos yourself .
