Mesothelioma and Asbestos

Asbestos, a natural mineral, naturally occurs in the form of thin, long fibers. People who are exposed to asbestos risk developing lung diseases like mesothelioma.

It may take decades for symptoms to show up after exposure to asbestos. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the lung's outer lining, or pleura. It is the most prevalent form of mesothelioma and accounts for 70% to 79% all diagnosed cases. People with this condition suffer from chest pain and shortness of breath and may experience a sensation of heaviness in the chest.

Exposure to asbestos, a family of minerals comprised of microscopic fibers, usually causes this kind of cancer. These fibers, when inhaled cause irritation and DNA mutations. Pleura surrounds both the chest cavity and the lungs, which means that irritations can also affect the heart. Mesothelioma usually doesn't show symptoms until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most frequent symptoms. Some patients also experience difficulty breathing, or chest tightness. People with this cancer have a history of disease that includes asbestos exposure at work. Construction, manufacturing, and shipbuilding are the most prevalent jobs that put people at high chance of developing pleural mesothelioma. People who were in the military are at greater risk due to the widespread use of asbestos in Navy vessels and bunkers in the Army.





The TNM (tumors lymph nodes and metastases staging system) is the most common staging system used for pleural adenocarcinoma. The stage a patient has upon diagnosis will aid their doctor in determining the most appropriate treatment plan for them. Patients with pleural mesothelioma that is in stage three or four will have a less favorable outlook than those in a lower stage. Mesothelioma in stage four is usually spread to the diaphragm, the liver or even the heart of a patient. This makes it more difficult to treat and raises the chance of complications for patients.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which develops in the lung lining, peritoneal mesothelioma is found in the peritoneum - it is a membrane that lines the abdominal cavity and organs such as the liver and intestines. Similar to pleural mesothelioma mesothelioma is triggered by asbestos exposure. The disease is less prevalent than pleural mesothelioma, with only about 300-500 cases diagnosed each year.

As with pleural asbestosis, symptoms can take years to manifest. Vimeo have abdominal pain, and may have a mass in their abdomen. The symptoms of this kind of mesothelioma can also include nausea as well as weight loss and fever. Many of these symptoms could be misinterpreted as gastrointestinal issues, leading to a misdiagnosis.

Generally speaking, doctors can detect mesothelioma after a thorough health history and physical examination. Imaging tests such as X-rays or CT scans can be used to detect mesothelioma. These tests can reveal cancerous tumors or other indications of cancer that aren't apparent on an X-ray.

These tests enable doctors to diagnose mesothelioma and determine the stage of the disease and suggest treatment options. The stage is determined by the type of cell as well as whether the cancer has spread.

The most important mesothelioma-related risk factor is exposure to asbestos. People who have been in occupations that involve asbestos, such as plumbing electrical work, manufacturing or construction, are at greater risk of developing the disease. Even if an individual does not work in any of these areas however, they may still be exposed to asbestos through family members and other sources. Anyone who suspects that they may be at risk should speak with an expert. If they have an history of exposure to asbestos, a mesothelioma specialist can assist them in finding out more about the risk.

Risk Factors

Asbestos is the most significant mesothelioma-related risk factor. It is responsible for as much as 80% of all cases. Exposure to asbestos can occur through military service, work, or living with those who worked with asbestos. When exposed to asbestos, small particles are able to be inhaled into abdomen and lungs. The particles cause irritation to the linings of the lungs, causing cancerous cells to form in the mesothelium. After exposure to asbestos mesothelioma can be diagnosed between 15 and 60 years.

Other risk factors include smoking, genetics and age. People in their 40s and 50s are at a higher risk of developing mesothelioma compared to those younger or older. This is because mesothelioma typically lasts between 20 and 60 years from the first time of exposure before the first signs of cancer appear. It is important to note, too, that mesothelioma can develop in people who have been exposed to asbestos, but without having worked with it directly. This is known as indirect or secondary exposure to asbestos and it could be as hazardous as direct exposure.

Smoking increases the risk of mesothelioma, because it damages the mesothelium. It also makes it more susceptible. Furthermore, mesothelioma is worsened by certain diseases like asbestosis and pneumonia. Men are more likely to develop mesothelioma than females. This is due to the fact that men are more likely to work with asbestos and experience a more exposure than women. Men are also more likely to have lived with someone who has been exposed to asbestos, and to carry asbestos fibers on their clothing. Women are less likely to be in contact with asbestos, and they are less likely to carry asbestos on their clothing.

Diagnosis

Mesothelioma is a difficult disease to diagnose because the symptoms often resemble other diseases. This can lead to victims being misdiagnosed.

NYU Langone doctors will perform an examination of the body and document the patient's medical background, including asbestos exposure. Doctors may also request an CT scan or chest X-ray in order to look for lumps, abnormalities, and evidence of exposure to asbestos. These include pleural plaques, thickened pleura and calcium deposits.

Other diagnostic tests include a magnetic resonance scan, or MRI test, which makes use of magnets and radio waves in order to produce a series of precise images of the inside of the body. Another way for doctors to detect mesothelioma is by performing a surgical biopsy. When a biopsy is performed, doctors remove a tiny piece of tissue from the pleura or the peritoneum to be tested further. A pathologist can look at the tissue under microscopes to determine whether it is contaminated with cancerous cells.

Mesothelioma is classified according to the type of mesothelial cells involved, whether those cells are benign or malignant, and the location, type, and stage of the cancer. Certain types of mesothelioma are at greater risk of spreading or metastasizing and it's crucial to get a definitive diagnosis to ensure that the doctors can treat it before it becomes out-of-control.

Doctors can also run tests in the lab on a tumor to identify specific genes, proteins, or other factors that can help them describe the cancer's characteristics and plan treatment. These results are referred to as staging.

Treatment

A mesothelioma diagnosis is an incredibly frightening prospect. It is important to keep in mind that cancer can be treated, particularly in its early stages. Many people with mesothelioma can be afflicted for many years without it expanding.

Exposure to asbestos can cause mesothelioma through a variety of ways. Asbestos particles, which are too small to be able to see or feel with the naked eye, can become airborne and irritate the lining of the lungs (pleura). Over time irritation can lead to formation of scar tissue which can cause changes in the structure of cells that can eventually grow into tumors.

The Pleura is a covering that protects the abdomen, heart, and lungs. Mesothelium is made up of cells that react to asbestos, causing it to inflame and form scar tissue. In time, these changes can cause the development of malignant mesothelioma tumors.

Shortness of breath, chest pain or fluid accumulation on the lungs are all indications of the pleural msothelioma. In rare cases the cancer may spread to the tissues surrounding the heart and reproductive organs.

If scans of imaging reveal an underlying mass in the lungs or stomach doctors will recommend a biopsies. During the procedure, doctors remove a small sample of the tumor or fluid for lab analysis. The results can confirm the diagnosis of mesothelioma and determine the most effective treatment plan.

There are many types of mesothelioma treatments, which include chemotherapy, surgery, and immunotherapy. Most doctors utilize the combination of these methods. Enrolling in clinical trials of mesothelioma treatments may be beneficial to patients. Patients can find out more by consulting a mesothelioma specialist who has treated mesothelioma.
