Mesothelioma and Asbestos

Asbestos is a naturally occurring mineral that is made up of long, thin fibres. People who are exposed to asbestos may develop lung diseases, such as mesothelioma.

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

Pleural Mesothelioma

Pleural mesothelioma can be found in the lung's outer lining or pleura. It is the most prevalent type of mesothelioma, making up between 70 and 79% of diagnosed cases. Patients with this disease feel chest pain and breathlessness and may experience an ache or heaviness in the chest.

This kind of cancer is often caused by exposure to asbestos, which is a collection of minerals comprised of microscopic fibres. These fibers, when inhaled cause irritation and DNA mutations. The pleura is the area that surrounds the lungs and chest cavity, so these irritations can affect both the lungs as well as a person's heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

Chest pain and shortness breath are the most frequently reported symptoms. Some patients 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. The most prevalent jobs that put people at risk of developing pleural cancer are manufacturing, construction, and shipbuilding. Individuals who have served in the military are at greater risk due the extensive use asbestos in Navy vessels and bunkers in the Army.

The TNM (tumors, lymph nodes, and metastases staging system) is the most commonly used staging system for the pleural adenocarcinoma. The stage a patient is in at the time of diagnosis will help determine what treatment plan they should receive. For example, patients with mesothelioma that is pleural in stage three or four have a poorer prognosis than those with a lower stage. Stage four mesothelioma may develop into the liver, heart or diaphragm. This could make the cancer more difficult to treat and increase the risk of complications for patients.

Peritoneal Mesothelioma

In contrast to pleural cancer, which is found in the lining of the lung, peritoneal cancer develops in a membrane that surrounds the abdominal cavity, including organs like the liver and intestines. Like pleural mesothelioma, asbestos claim exposure is the primary cause of peritoneal msothelioma. The disease is less prevalent than pleural mesothelioma, with just 300-500 cases being diagnosed each year.

As with pleural asbestosis symptoms can take years to show. Most patients suffer from abdominal pain and abdominal swelling. This type of mesothelioma may cause nausea, weight loss, and fever. Many of these symptoms are similar to those experienced by gastrointestinal issues, which can result in incorrect diagnosis.

Typically, doctors can identify mesothelioma by conducting an exhaustive health history and physical examination. Imaging tests like X-rays and CT scans can be used to identify mesothelioma. These tests can identify tumors and other signs of cancer that aren't evident on X-rays.

These test results allow doctors to diagnose mesothelioma and determine the stage and recommend treatment options. The stage is determined by the type of cell and whether the cancer has spread.

The most important risk factor for mesothelioma is asbestos exposure. People who have worked in asbestos-related occupations, like electrical or plumbing work or in manufacturing and construction, are more likely to contract the disease. Even if an individual does not work in one of these areas however, they may be exposed to asbestos to asbestos settlement through family members and other sources. Anyone who suspects that they are at risk should consult a doctor. If they have a history of asbestos exposure or mesothelioma, a specialist can help them find out more about the risk.

Risk Factors

Asbestos is the primary risk factor in mesothelioma. It is responsible for up to 80percent of cases. Exposure to asbestos can happen through military service, work or living with people who have worked with asbestos. When exposed to asbestos, the particles can be inhaled into the abdomen and lungs. These particles can cause irritation to the linings and trigger cancerous cells to develop in the mesothelium. Mesothelioma can take anywhere between 15 and 60 years to develop after exposure to asbestos.

Other risk factors include smoking, genetics and age. People in their 40s and 50s are more likely to be diagnosed with mesothelioma compared to those who are younger or more senior. It takes mesothelioma 20-60 years before it manifests cancer symptoms after the first exposure. It is important to keep in mind, too, that mesothelioma can be present in people who have been exposed to asbestos without having worked with it directly. This is known as secondary or indirect asbestos exposure. It can be just as harmful as direct asbestos exposure.

Smoking increases a person's chances of developing mesothelioma since it causes mesothelium damage and makes it more prone to asbestos claim. In addition, mesothelioma may be exacerbated by certain illnesses like pneumonia and asbestosis. Men are more likely to develop mesothelioma than women. This is because men are more likely to be exposed to asbestos and endure a an extended period of exposure than women. Men are also more likely to have lived with someone who has worked with asbestos and to have asbestos-containing fibers on their clothing. Women tend to have less exposure to asbestos and don't typically carry asbestos home on their clothes.

Diagnosis

Mesothelioma is a difficult cancer to identify because the symptoms can be similar to other conditions. This can result in patients being incorrectly diagnosed.

NYU Langone doctors will perform an examination of the body and document the patient's medical history including asbestos exposure. Doctors will also recommend an CT scan or chest X-ray to check 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 radio waves and magnets to produce a series of precise images of the insides of the body. A surgical biopsy is another method for doctors to identify mesothelioma. When a biopsy is performed doctors will remove a small part of tissue from the pleura or the peritoneum to be examined further. A pathologist can look at the tissue under a microscope to see if it has cancerous cells.

Mesothelioma can be classified based on the type of mesothelial cell involved, whether those cells are benign or malignant, and the location, type, and stage of the cancer. Certain mesothelioma types have a higher risk of metastasizing or spreading and it's crucial to establish a clear diagnosis so doctors can treat it before it becomes out of control.

Doctors may also conduct tests in the laboratory on tumors to identify specific genes, proteins, or other factors which can aid in describing cancer characteristics and determine the best treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be an incredibly frightening prospect. It is crucial to remember, however, that cancer can be treated particularly in its early stages. Many patients with mesothelioma live with the disease for a long time, without spreading.

Exposure to asbestos can cause mesothelioma in many ways. Asbestos fibers, which are small enough to not be felt or seen through the naked eye are able to become airborne and irritate the lining of the lung (pleura). As time passes, the irritation leads to the formation of scar tissue and eventually tumors.

The pleura is a protective covering that surrounds the abdomen, heart, and lungs. Mesothelium is made up of cells that react to asbestos which causes it to become inflamed and form scar tissue. These changes can eventually lead to malignant mesothelioma tumours.

Breathing problems, chest discomfort or fluid buildup on the lungs are all signs of pleural Msothelioma. In rare cases the cancer may be spread to the tissues around the heart and reproductive organs.

A doctor will order a biopsy if imaging scans show the possibility of a lung tumor or stomach. During the procedure, doctors remove small amounts of the tumor or fluid for lab analysis. The results will confirm the diagnosis of mesothelioma and determine the best treatment option.

There are several types of mesothelioma treatment options, which include chemotherapy, surgery, and immunotherapy. The majority of doctors employ the combination of these treatments. Participating in clinical trials for new mesothelioma treatment may also be beneficial to patients. Patients can learn more by speaking with a mesothelioma doctor who has treated the disease.
