A person who is exposed to asbestos inhales or ingests fiber that is not really visible to the naked eyes. Over time these fibers react with the body cells in a manner that they undergo mutation and cause malignant Mesothelioma. This exposure can be direct and also indirect, when family members and friends come in contact with the person who is exposed to asbestos.

Types of Mesothelioma

The first type of Mesothelioma is called Pleural Mesothelioma and this affects the inner lining of the lungs which is called the pleura. When the fibers of asbestos are inhaled they cause he formation of scars and damage the cells present in the inner lining. This leads to the onslaught of mesothelioma cancer. This is the most common type of Mesothelioma and the symptoms are breathlessness, pain the chest, retention of fluid in the lungs and blood traces in the sputum.

The next type of Mesothelioma is called Peritoneal Mesothelioma and it affects the inner lining of the stomach. This happens when the fibers of asbestos enter the body and interfere with the normal cells penetrating their thin lining. This is not very common, but the onslaught manifests in the form of symptoms that include pain in the abdomen, feeling of nausea, constipation, lumps of tissue in the abdomen etc.

The third type is the Pericardial Mesothelioma and this affects the lining around the heart. There are very few cases of this type of cancer diagnosed and the symptoms include chest pain, palpitations and mild cough.

Mesothelioma life expectancy

This is a very dangerous form of cancer and a person who is diagnosed does not live for more than two years. The danger is more from the fact that the symptoms only manifest decades after initial exposure to asbestos fiber. Though the main cause is exposure to asbestos, this is not the only cause. It takes about 30 to 40 years to surface after initial infection. But the main cause for worry is that by the time it gets diagnosed it is usually in the last stages. The Mesothelioma life expectancy is less than two years and this time period is very painful, mentally and physically. There are many doctors and surgeons who are constantly experimenting with treatments and prevention methods, feeling very positive that the Mesothelioma Life Expectancy can be increased to almost 5 years. If this is possible then it will be a great achievement in the world of medicine because as of today Mesothelioma is a 'dreaded' silent killer.

Benefits of early diagnosis

A person who has been exposed to asbestos at any point of time in life is always advised to get checked for Mesothelioma. Even if you are not directly exposed, even if a family member is exposed it is better to get yourself and your family checked for signs. Since it takes a long time for the symptoms to surface your current state of health is not a criterion. Even if you are completely fine now getting yourself checked does no harm. It is better to get checked before the symptoms show up because then it will be too late.

There are many types of cancers and most of them are the result of causes yet unknown. But Malignant Mesothelioma is due to the exposure to asbestos and Mesothelioma Life Expectancy is imperative to know the types of this cancer.

Due to asbestos exposure Asbestosis and Malignant Mesothelioma are caused. The condition also leads to lung cancer if not treated in time. Mesothelioma life expectancy reduces greatly in those patients who do not receive treatment on time.

Lethal exposure to Asbestos:

Asbestos appears in a naturally fibrous form and is basically recognized as a class of minerals. It is used in the manufacturing industry and has many other uses due to its properties of chemical resistance, heat resistance and flexibility. It is extensively used in ship building material, roofing material and building material. When a person is constantly subjected to the inhalation of the asbestos fibers for a long period of time, the asbestos exposure endangers the person's health.

The fibers are not visible to the naked eye. They are microscopic, and get lodged firmly in the lungs when they are constantly inhaled. The first manifestation can take up to 40 years to surface, with the least time span being about 15 years since the initial exposure. Health takes a beating with asbestos inhalation in the form of malignant mesothelioma, lung cancer and asbestosis.

Other cancers:

There are other cancers caused due to asbestos exposure too. Cancer of the kidney, oral cavity, colon, stomach and larynx are included. Cancer of the intestines, stomach and esophagus is caused due to constant exposure to asbestos fiber in the drinking water. Smoking and prolonged asbestos exposure are hazardous and result in lung cancer.

If smoking is quit as soon as possible, then the risk of developing lung cancer gets reduced greatly. Once asbestosis is diagnosed, mesothelioma life expectancy decreases in the presence of a cigarette smoking addiction. Those who smoke and have had prior exposure to the asbestos fiber should immediately quit smoking. Even those who have been subjected to low levels of asbestos inhalation over a long period of time can develop malignant mesothelioma. It is one of the most painful cancers of all.

After long term exposure to asbestos, the fibers get lodged into the lungs firmly causing asbestosis. This disease can be contained with early diagnosis and proper treatment. However, if it is ignored and/or it is worsened with further inhalation of asbestos fibers and/or smoking, it leads to lung cancer and subsequently decreased Mesothelioma Life Expectancy.

Prevention:

However small the job might be, when you get an old construction razed or renovated never attempt doing it yourself. Professionals are aware of the risks involved and they ensure that neither they nor you get exposed to the asbestos fiber or the diseases associated with it. Those at risk are those directly involved in servicing of brake and auto clutch assemblies, building renovators, ship breakers, ship and house building etc.

It was way back in the 1920s that the connection between lung cancer and asbestos inhalation was detected. When different variants of asbestos like crocidotile, amosite, chrysostile, and anthophyllite are inhaled, lung cancer is the lethal outcome. Those suffering from asbestosis develop lung cancer. The condition is now also being addressed by the keepers of the law with compensations that make the fiscal demands bearable.

Malignant Mesothelioma and Mesothelioma Life Expectancy many other related diseases like Asbestosis are cause due to asbestos exposure. This recognized human carcinogen is primarily responsible for causing lung cancer too.

Overview of Malignant Mesothelioma

Comments (0)

Over a period of time, the world has witnessed variations of a disease that is caused by the frequent inhalation or ingestion of asbestos fibers - mesothelioma. The asbestos fibers are known to get lodged within the lung tissues. A variety of related diseases are caused due to prolonged and constant exposure to asbestos like malignant mesothelioma, lung cancer and asbestosis. The most fatal of these diseases is mesothelioma, which culminates in death.

Malignant mesothelioma:

This cancer affects the lining of the abdomen or the lungs and is today, not a very rare type of cancer. It is always caused due to the inhalation of asbestos, but can spread due to a weakened immune system too and other internal infections present during the onslaught. The effects of this cancer manifest approximately 20 to 40 years later and this is one reason why it is seen in older patients generally. If mesothelioma life expectancy has to be increased then early diagnosis of the patient helps in determining the right kind of treatment option on time. Of all the cancers, malignant mesothelioma is one of the most painful, aggressive and most fatal.

Mesothelioma cancer types:

The lungs are often the most affected parts of the body in mesothelioma cancer. It also occurs in the peritoneum in rare cases and when the asbestos fibers are inhaled, they also reach the bowel and stomach regions. Pleural mesothelioma and peritoneal mesothelioma are the two types of mesothelioma. The pleura or the lining of the lungs are affected in pleural mesothelioma and in peritoneal mesothelioma, the lining of the abdominal cavity or the peritoneum is affected.

Risk:

To improve mesothelioma life expectancy early diagnosis and treatment becomes indisputable. It takes many years for malignant mesothelioma to develop and manifest. If a person is diagnosed today for example, he or she has actually been exposed to the asbestos fibers about 20 to 40 years back! Those workers who previously had jobs involving prolonged inhalation of the asbestos fiber are the ones most affected by mesothelioma. During the early 20h century, there were not many safety guidelines with regards to the onslaught. Not only the workers themselves, but even their friends and relatives were affected due to the inhalation of the asbestos fibers from the hair, clothing and skin of these primary carriers of the fibers.

Prognosis and symptoms:

It takes decades for malignant mesothelioma to develop. Up to 15 to 20 or sometimes even up to 50 years, no serious symptoms of the condition may manifest in even a construction worker. And even if the symptoms do surface, they have a tendency of remaining inconspicuous very often. The patient usually displays bouts of fever, swallowing difficulty, and pain in the chest, shortness of breath, persistent cough and difficulty in breathing.

It becomes difficult to catch the onslaught in the early stages due to the vagueness of the symptoms related to malignant mesothelioma. The cancer is most likely to reach its advanced stages by the time the victim even goes through the primary diagnosis. This makes the prognosis poor and the situation pretty hapless. Depending on the particular form of mesothelioma cancer, the survival rate could be anywhere between 20-30%. To improve Mesothelioma Life Expectancy, early diagnosis and the timely treatment are absolute necessities.

Right from the 1800s asbestos has been frequently used and even overused. The overview of Mesothelioma Life Expectancy and Malignant Mesothelioma needs to be mapped from the 1940s to the 1980s.
