Mesothelioma and Asbestos

Asbestos is a natural mineral that comes in thin, long fibres. People who are exposed to asbestos legal on a regular basis are at risk of developing mesothelioma or other lung diseases of different types.

It could take a long time for symptoms to appear after asbestos exposure. Different types of asbestos can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a type of cancer that affects the outer lung the lining (pleura). It is the most frequent type of mesothelioma, making up 70 to 79% of diagnosed cases. Patients with this disease suffer from chest pain and breathlessness and may experience the sensation of weight in the chest.

This type of cancer often caused by exposure to asbestos, which is a cluster of minerals that are made up of microscopic fibres. When inhaled, these fibers can cause irritation and DNA mutations. The pleura surrounds the chest cavity and lungs, so these irritations can affect both the lungs as well as a person's heart. Mesothelioma typically doesn't manifest until 30 to 50 years after exposure.

Chest pain and shortness breath are the most frequently reported symptoms. Patients may also experience coughing, difficulty breathing or chest tightness. Patients with this type of cancer typically have an history of exposure to asbestos in the workplace. Construction, manufacturing and shipbuilding are the most frequent occupations that put people at high danger of developing pleural melanoma. Individuals who have served in the military are at a greater risk due to the widespread use of asbestos in Navy vessels and Army bunkers.

The most popular staging system for pleural mysothelioma has been the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage a patient has at diagnosis will aid their doctor in determining the best treatment plan for them. For instance, patients who have mesothelioma pleural stage three or four have a poorer prognosis than those with a lower stage. Stage four mesothelioma can be spread to the liver, heart or diaphragm. This can make the cancer more difficult to treat, and increase the risk of complications for patients.

Peritoneal Mesothelioma

In contrast to pleural mesothelioma which is a lung-lining cancer, peritoneal mesothelioma develops in the peritoneum - it is a membrane that lines the abdominal cavity and organs such as the liver and intestines. Like pleural mesothelioma, asbestos exposure is the cause of peritoneal mesothelioma. The disease is much less prevalent than pleural mesothelioma, and just 300-500 cases being diagnosed each year.

As with pleural asbestosis symptoms can take a long time to manifest. Patients generally have abdominal pain, and may also have a lump in their abdomen. The symptoms of this type of mesothelioma may also include nausea as well as weight loss and fever. Many of these symptoms are similar to symptoms of digestive problems, which can cause misdiagnosis.

The doctors can detect mesothelioma through examining the patient's medical history and performing a physical exam. Imaging tests such as X-rays or CT scans are a way to identify mesothelioma. These tests can identify tumors as well as other signs of cancer that aren't visible on X-rays.

These test results enable doctors to diagnose mesothelioma and establish the stage. They can also suggest treatments. The stage is determined by the type of cell and whether the tumor has spread.

The most significant risk factor for mesothelioma is asbestos exposure. People who have worked in jobs that involve asbestos, such as plumbing, manufacturing, electrical work or construction, are at greater risk of developing the disease. Even if an individual is not employed in one of these fields however, they may be exposed to asbestos through family members and other sources. Therefore, anyone who suspects they may be at risk should speak to an experienced doctor. A mesothelioma specialist can assist those who have a history with asbestos to learn more about their risk.

Risk Factors

Asbestos is the main risk factor in mesothelioma. It is responsible for as much as 80% of all cases. Exposure to asbestos can happen due to military service, work or living with people who have worked with asbestos. Asbestos particles are inhaled by those who are exposed to asbestos. These particles irritate the linings of the lungs, causing cancerous cells to grow in the mesothelium. After asbestos exposure mesothelioma can occur between 15 and 60 years old.

Other risk factors include smoking, genetics, and the advancing age. The people in their 40s or 50s are more at risk of developing mesothelioma as compared to those younger or older. This is because mesothelioma typically takes 20 to 60 years from the first exposure before the first signs of cancer appear. It is important to note, too, that mesothelioma may be present in those who have been exposed to asbestos claim, but without having directly worked with it. This is called indirect or secondary exposure to asbestos, and it could be as hazardous as direct exposure.

Smoking increases the chance of mesothelioma developing, as it damages the mesothelium. It also makes it more prone to. In addition, mesothelioma may be caused by certain illnesses, such as asbestosis and pneumonia. Men are more likely to develop mesothelioma than women. This is because men are more likely to work with asbestos and experience a a longer period of exposure than women. Men are also more likely to have lived with someone who has worked with asbestos case [Recommended Web site] and to have asbestos fibers on their clothing. Women are less likely to be in contact with asbestos, and they don't usually bring asbestos home on their clothing.

Diagnosis

It is difficult to recognize mesothelioma because its symptoms are often similar to other diseases. Due to this, patients are often wrongly diagnosed.

The first step to diagnose mesothelioma is for NYU Langone doctors to perform an examination of the body and take note of the medical history of the patient which includes asbestos exposure. Doctors will also recommend an CT scan or chest X-ray in order to look for abnormalities, lumps and evidence of asbestos exposure. These include plaques on the pleura, pleura that are thickened and calcium deposits.

Other diagnostic tests include a magnetic resonance imaging or MRI test, which uses radio waves and magnets to produce a series of precise images of the insides of the body. Another method doctors use to diagnose mesothelioma is by performing an operation called a biopsy. A surgical biopsy is when doctors take a small amount of tissue from the peritoneum or pleura for further analysis. A pathologist will then look at the tissue under an magnifying glass to determine if it is a cancerous cells.

The mesothelial type involved as well as the benign or malignant nature of the cells as well as the location, type and stage of the cancer are used to classify the disease. Certain mesothelioma types have an increased risk of metastasizing or spreading therefore it is essential to get a definitive diagnosis to ensure that the doctors can treat it before it gets out-of-control.

Doctors can also perform tests in the laboratory on tumors to identify specific proteins, genes, or other factors which can help them describe the characteristics of cancer and plan treatment. These results are known as staging.

Treatment

A mesothelioma diagnosis can be an incredibly frightening prospect. It is crucial to remember that cancer can be treated particularly in its early stages. Many mesothelioma patients live for years with the disease without it spreading to other organs of their body.

Asbestos exposure can cause mesothelioma through a variety of mechanisms. Asbestos fibers, too small to see or feel with the naked eye, can become airborne and cause irritation to the lung's lining (pleura). As time passes, the irritation leads to the formation of scar tissues and eventually tumors.

The Pleura is a covering that surrounds the lungs, heart and abdomen. Mesothelium is composed of cells that react to asbestos and cause it to enflame and develop scar tissue. These changes can eventually result in malignant mesothelioma tumors.

Symptoms of pleural mesothelioma include breathlessness and chest pain, or an accumulation of fluid in the lungs (pleural effusion). In rare instances, the cancer can spread to the tissues surrounding the heart and reproductive organs.

If scans of imaging reveal an underlying mass in the lungs or stomach the doctor will request biopsies. During the procedure, doctors remove tiny amounts of fluid or tumor for laboratory testing. The results will confirm a mesothelioma diagnosis and provide the best treatment option.

There are a variety of treatment for mesothelioma such as chemotherapy and surgery. The majority of doctors use an amalgamation of these techniques. Patients could also benefit from enrolling in a clinical trial of new mesothelioma therapies. Patients can find out more by speaking with a mesothelioma doctor who has treated the condition.
