Mesothelioma is a form of cancer that is almost always caused by being exposed to asbestos. In this illness, malignant cells develop in the mesothelium, a protecting lining that covers the majority of the body’s internal organs. Its commonest site is the pleura ( outer liner of the lungs and internal chest wall ), but it may also occur in the peritoneum ( the lining of the abdominal cavity ), the heart, the pericardium ( a sac that surrounds the heart ) or tunica vaginalis.

Mesothelioma is a rare cancer which usually occurs on the outer surface of the lungs, and most who are diagnosed have been in prolonged contact with asbestos, although it can occur in those who have never been exposed .

In the human body, the pleural cavity is the cavity that surrounds the lungs. The pleura is a membrane which basically folds back to create two layers. The space created between these two layers is what is known as the pleural cavity. Normally there is some fluid found in this cavity. The outer pleura, also known as the parietal pleura, is attached to the thoracic wall. The inner pleura, or visceral pleural, is found over the lungs and related blood vessels, nerves and bronchi.

Surgery for lung cancer (LC) was once performed exclusively through thoracotomy. A long incision was made into the patient’s chest. Then, the ribs were either cut and removed, or spread apart to provide the surgeon with enough working space within the chest cavity. This was the approach taken for wedge resections (removal of a portion of the tissue) lobectomies (removal of a lobe), and pneumonectomies (removal of an entire lung).

Over 85% of diagnosed cases of lung cancer (LC) are attributable to smoking tobacco products. Given that, it is surprising that many people (including those who are directly exposed to cigarette smoke) remain unaware of how the habit influences the onset of the disease. Most people understand the connection; they recognize that smoking can increase the likelihood of developing cancerous cells. Yet, their understanding seldom extends further.

The survival rate among those who suffer from lung cancer (LC) drops sharply as the disease progresses. If the condition is diagnosed while it is still in Stage I, and treatment begins immediately, the five-year survival rate climbs above 75%. On the other hand, if the illness reaches Stage IV, there is only a 10% probability of survival. This is the reason doctors recommend learning how to identify the symptoms of the disease. The more quickly you do so, the greater the chances the cancerous cells can be eliminated.

The success of mesothelioma treatments depends on the stage of the cancer at the time of detection. Physicians follow several treatment methods, both traditional and modern. Conventional therapies include surgery, radiation and medications like chemotherapy or a combination of two or three of these. More than two-thirds of stage-1 and stage-2 mesothelioma patients usually get their lives extended by five years or more, and surgery itself has succeeded in doing the same in around sixteen percent of all cases. Surgery involves removing the cancerous growth through surgical incisions. The most common surgery here is the decortication or pleurectomy in which the chest lining is removed. The extrapleural pneumonectomy (EPP), which removes the lining around the lung, inside the chest, the hemi-diaphragm and pericardium, is less common.

As well as a whole host of life threatening illnesses, lung cancer is the then most common and serious illness caused by smoking. Although it can be contracted by non smokers, it is almost exclusively smoking related and in fact 9 out of 10 fatalities from lung cancer are smokers. Although stopping smoking does have a beneficial effect against getting lung cancer it does not completely eradicate the chances of an ex smoker dying from the illness. Unfortunately for the ex smoker, the harmful toxins that are released into the lung tissue through smoking can in fact remain present for between 10 and 15 years after the last cigarette and although the body will eventually break them down it can be a very slow process.

When many people consider treatment for lung cancer, they initially think of surgery. While a wedge resection, partial or full lobectomy, or pneumonectomy may be necessary, there are other approaches that can be taken to help eliminate cancerous cells. They include chemotherapy, radiation therapy, and various targeted therapies. In many cases, doctors will suggest a multi-pronged approach that combines surgical and non-surgical forms of treatment.

The endless greed of a set of people, which includes unscrupulous industrialists, results in mesothelioma, a deadly form of cancer. Inhaling the air contaminated with asbestos particles results in contracting the disease.
