Mesothelioma Cancer

Mesothelioma is a form of cancer that is triggered by exposure to asbestos. Inhaling asbestos litigation fibers cause mesothelioma of the pleura and swallowing asbestos can cause mesothelioma peritoneal.

The symptoms may be similar to those of less serious illnesses. They can take 10 - 50 years before they appear. The symptoms include breathlessness, chest pain and abdominal distress.

Risk Factors

Mesothelioma occurs when asbestos fibres enter the body. Pleural mesothelioma is a form of cancer that develops in linings of the chest cavity or the lungs. Mesothelioma can also develop in the peritoneum (the membrane that surrounds the heart) or the pericardium. The cancer may take up to 50 years to develop and manifest symptoms. These symptoms are often mistaken for flu like illnesses. Mesothelioma is most often found in older people, and is more prevalent in men than women.

The main risk factor for mesothelioma is exposure to asbestos. Asbestos is a natural mineral that is made up of tiny fibres which were employed in construction materials, like ceilings and walls due to its resistance to fire and heat. It was also employed in the production of products like pipes, insulation, shingles and cement. Workers in industries where asbestos was a common ingredient, such as construction, mining or shipbuilding are at risk of developing mesothelioma. However even those who had secondary exposure such as relatives who brought home asbestos on their clothes and skin, are at risk.

A small percentage (less than 5percent) of mesothelioma is linked to a mutation in the BAP1 gene. This genetic change can increase the risk of developing mesothelioma in those who have been exposed to asbestos.

The patient's age is also an indicator of risk. Mesothelioma is most common in people older than 45 years, and two thirds of those who are diagnosed with it are 65 years old or older. This is partly due to the long latency time that is associated with asbestos exposure however, it could be due to the fact that the condition is more prevalent in older patients who have experienced more extensive and prolonged exposure to the cancer-causing material.

Mesothelioma is more prevalent in white males than women or people of any other racial group. This is due to the fact that historically more white men worked in occupations that put them at a greater risk of asbestos legal exposure than other groups. Mesothelioma is most often afflicted by those who were exposed to asbestos before the 1980s, when more strict regulations were in place.

Symptoms

Mesothelioma is an asbestos-related cancer that develops in the linings that protect various organs in the body. The cancerous tumors that form in the tissue could damage them and cause severe pain. The malignancy can expand to other areas through the lymphatic or bloodstream system.

Mesothelioma symptoms may be similar to symptoms of other diseases, like pneumonia or the flu. It usually takes between 10 and 50 years to show up after exposure to asbestos. This delay in time makes it difficult to recognize mesothelioma early. Additionally, the symptoms could be misinterpreted as other diseases.

Most malignant tumors begin in the lungs or chest cavity (pleura). But mesothelioma can also form in the linings of the heart and abdomen. In rare instances, the disease can even affect the lining of the testes or the sac that surrounds the heart (pericardium).

Asbestos is a class of minerals that form long, thin fibers. These fibers are so durable that they cannot be broken down by chemicals and water, or by bacteria. They were widely used in various construction and household products for a long time before scientists realized how harmful they were to health.

The majority of mesothelioma cases are caused by exposure to asbestos at work or home. The majority of patients who were exposed were employed by the US Navy Air Force, Shipbuilding Industry or Construction. Men are more likely to develop mesothelioma compared to women. Veterans comprise about 30 percent of all cases.

Imaging scans and medical tests can aid doctors in identifying mesothelioma. This includes X-rays CT scanners, MRIs, and PET scans. The doctor could also collect a small sample of the tissue and send it to a laboratory to be tested.

The results can help doctors determine the mesothelioma type and stage of the disease which can affect the prognosis as well as treatment options. The majority of mesothelioma types are epithelioid and sarcomatoid. Between 10 percent and 15% of cases are biphasic or mixed. Epithelioid mesothelioma tends to be less aggressive and has the highest survival rates. Sarcomatoid mesothelioma has a worse prognosis and is more difficult to treat.

Diagnosis

It is difficult to recognize mesothelioma, especially at an early stage. The first step is for patients to visit their primary care doctor with any symptoms, like chest pains or coughing. The doctor will utilize a stethoscope to listen to the patient's breathing and take note of their medical history and work history. This includes any history of asbestos law exposure, which is important in determining mesothelioma's diagnosis.

Doctors must rule out other diseases before they can confirm a diagnosis because mesothelioma symptoms are similar to those of other diseases. Cancer can infect the lungs of a patient from other parts of the body such as the chest or abdomen. Asbestos sufferers are at risk of lung problems, including pneumonia, and pleural mesothelioma symptoms may be confused with other respiratory ailments.

Blood tests, imaging tests and biopsy are all used to identify mesothelioma. These tests will aid in locating the site of the cancer, which is often found in the lungs, but could also be found in the stomach or the testicles. These tests can also help doctors determine the extent of the cancer is growing throughout the body.

A CT scan or MRI can reveal mesothelioma signs including calcium deposits in the pleura (known as plaque) and the accumulation of fluid between the lungs and chest wall. These tests can also determine whether a person has more lung tissue on one side or the other.

In many cases, a biopsy is necessary to confirm the diagnosis of mesothelioma. This involves removing small amounts of tissue and testing them in the lab for mesothelioma.

Certain patients may require additional tests, such as FDG-positron emission tomography (PET), which helps doctors understand how the tumor is affecting the blood supply to the lungs; mediastinoscopy, which permits doctors to look at and sample lymph nodes in the center of the chest as well as endobronchial ultrasound (EBUS), which uses sound waves to examine mesothelium and the lungs. Mesothelioma is a rare cancer, and doctors are still learning to treat it effectively. Patients who have been diagnosed with cancer need to carefully weigh their options to determine the best treatment for them.

Treatment

Mesothelioma can affect the lung's lining (pleural mesothelioma) or the abdomen (peritoneal mesothelioma) or the heart (pericardial mesothelioma). The symptoms typically do not show up until a few years after exposure to asbestos. This is why it's crucial for those who have been exposed to asbestos to be examined if they develop any strange symptoms.

A doctor will take an medical history to look for mesothelioma risk factors, for example, how long and how intensely someone was exposed to asbestos. A doctor can also perform an examination to determine mesothelioma signs, such as the accumulation of fluids in the chest cavity. The type of cells in the mesothelium and the locations of those cells are used to categorize mesothelioma. The most common mesothelioma type is epithelioid. It makes up between 60 and the majority of mesothelioma patients. Other mesothelioma types are sarcomatoid and biphasic mesothelioma, which both make up around 10 to 15% of mesothelioma cases.

There are a myriad of treatment options for patients with mesothelioma. The type of treatment is dependent on the stage and type of the mesothelioma.

In some instances, mesothelioma may be treated with chemotherapy or radiation. In these treatments, doctors inject powerful cancer-fighting drugs or use special equipment to destroy cancerous tumors and decrease the chance of mesothelioma returning.

Other types of mesothelioma can be treated through surgery that removes part of the lining from the affected organ. It can also alleviate symptoms like breathing problems.

If a person has mesothelioma pleural, their doctor may perform VATS, a procedure that involves the use of a camera into the lungs to remove part of the pleura and lung. This can improve breathlessness caused by fluid build-up in the lungs, however it is not a cure for the disease.

Other treatment options include support services or pain management. It is important for people with mesothelioma to get as much information as possible about the disease and ways to cope with it. The more educated they are and the more they are able to plan for a future that includes a variety of health and wellness activities.
