Mesothelioma and Asbestos

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

It can take years before symptoms begin to manifest after asbestos exposure. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the outer lung lining, or pleura. It is the most common mesothelioma that accounts for up between 70 and 79% of all diagnosed cases. Patients with this disease feel chest pain and breathlessness and may experience the sensation of weight in the chest.

Exposure to asbestos, a group of minerals composed of microscopic fibers, typically causes this kind of cancer. These fibers, when inhaled cause irritation and DNA mutations. The pleura is the area that surrounds the chest cavity and lungs and therefore, these irritations could affect both the lungs as well as the heart of a person. Mesothelioma typically doesn't manifest until 30 to 50 year after exposure.

The most common symptoms of pleural mesothelioma include chest pain and breath shortness. Patients may also suffer from chest tightness, coughing or difficulty breathing. Patients with this type of cancer have a history of disease that includes asbestos exposure at work. Manufacturing, construction, and shipbuilding are the most prevalent occupations that put people at high danger of developing pleural melanoma. People who served in the military are at a greater risk due the extensive use asbestos case - have a peek at this web-site, in Navy vessels and Army bunkers.

The most popular staging system for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage that a patient is at upon diagnosis will assist 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 in a lower stage. Stage four mesothelioma may be spread to the liver, heart or diaphragm. This makes the cancer more difficult to treat, and increase the chance of complications for patients.

Peritoneal Mesothelioma

In contrast to pleural mesothelioma which is a lung-lining cancer, peritoneal mesothelioma forms in the peritoneum - a membrane that lines the abdominal cavity and organs like the intestines and the liver. Like pleural mesothelioma, exposure to asbestos is the reason for peritoneal msothelioma. The disease is much less prevalent than pleural mesothelioma, and around 300-500 cases being diagnosed each year.

As with pleural mesothelioma symptoms can take a long time to manifest. Patients typically have abdominal pain, and may also have a lump in their abdomen. The symptoms of this kind of mesothelioma may also include nausea or weight loss, as well as fever. A lot of these symptoms are similar to symptoms of gastrointestinal issues, which can result in misdiagnosis.

Generally speaking, doctors can detect mesothelioma through a thorough health history and physical exam. Imaging tests such as X-rays or CT scans can be used to identify mesothelioma. These tests can show tumors, as well as other symptoms of cancer that aren't visible on an X-ray.

These test results enable doctors to identify mesothelioma, and determine the stage. They can also recommend treatment options. Staging is determined based on the cell type and whether or not the tumor has spread to other areas of the body.

The most important mesothelioma risk factor is asbestos exposure. People who have worked in asbestos-related professions, such as plumbing or electrical work, or in construction and manufacturing, are more likely to develop the disease. Even if an individual is not employed in one of these areas however, they may still be exposed through family members and other sources. For this reason, anyone who is concerned that they might be at risk should talk to an experienced doctor. A mesothelioma specialist can help those who have a previous history of asbestos to find out more about their risk.

Risk Factors

Asbestos exposure is the primary risk factor for mesothelioma, which accounts for as much as 80 percent of cases. Exposure to asbestos can occur as a result of military service, work, or living with people who have worked with asbestos. When exposed to asbestos, the particles can be inhaled into the lungs and abdomen. These particles can cause irritation to the linings, causing cancerous cells to grow in the mesothelium. After asbestos exposure mesothelioma is likely to be diagnosed between 15 and 60 years.

Other risk factors include genetics, smoking and age. People in their 40s or 50s are more at risk of developing mesothelioma as compared to people who are younger or more. It takes mesothelioma between 20 and 60 years before it manifests cancer symptoms after the first exposure. It is important to remember that mesothelioma may develop in those who were exposed to asbestos but did not work with it directly. This is referred to as secondary or indirect exposure to asbestos lawsuit and it can be just as dangerous as direct exposure.

Smoking increases the risk of mesothelioma, since it damages mesothelium. It can also make it more vulnerable. Furthermore, mesothelioma is worsened by certain diseases like pneumonia and asbestosis. Men are more likely to develop mesothelioma compared to women. This is due to the fact that men are more likely to work with asbestos law and have a longer period of exposure than women. Additionally, men are more likely to live with someone who had asbestos exposure and bring stray asbestos fibers home on their clothes. Women are less likely to come into contact with asbestos claim and don't typically carry asbestos around on their clothes.

Diagnosis

It is difficult to recognize mesothelioma because its symptoms are often similar to other diseases. Because of this, victims are often mistakenly diagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform an examination and write down a patient's medical history which includes asbestos exposure. Doctors will also recommend a CT scan or chest X-ray to check for lumps, abnormalities, and evidence of asbestos exposure. These include plaques in the pleura, thickened pleura and calcium deposits.

Other diagnostic tests include an echocardiogram which examines the blood vessels and the heart, and a magnetic resonance imaging, also known as MRI, test, which uses radio waves and magnets to make a series of precise images of the inside of the body. A surgical biopsy is a different method doctors use to diagnose mesothelioma. When a biopsy is performed, doctors remove a tiny piece of tissue from the pleura or the peritoneum to be further examined. A pathologist can then examine the tissue under an magnifying glass to determine if it contains cancerous cells.

Mesothelioma is classified according to the type of mesothelial cell involved, whether those cells are malignant or benign and the location of the tumor, its type, and the stage of the cancer. Some types of mesothelioma have greater risk of metastasizing or spreading and it's crucial to determine the type of mesothelioma to ensure that the doctors can treat it before it gets out-of-control.

Doctors can also run tests in the lab on tumors to determine particular proteins, genes and other factors that can help them describe the cancer's characteristics and plan treatment. These results are referred to 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 initial stages. Many patients with mesothelioma be afflicted for a long time, without expanding.

Asbestos exposure can cause mesothelioma through many mechanisms. Asbestos particles, which are too small to be able to see or feel through the naked eye, can be airborne and cause irritation to the lung's lining (pleura). In time, the irritation causes the formation of scar tissue which leads to changes in the structure of cells that eventually develop into tumors.

The pleura surrounds the heart and lungs and the abdomen. Mesothelium is made up of cells that react to asbestos settlement, causing it to inflame and develop scar tissue. In time, these changes can lead to the development of malignant mesothelioma tumors.

Breathing problems, chest discomfort or fluid buildup on the lungs are all indications of pleural mesothelioma. In rare cases cancer may spread to the tissues that surround the reproductive organs as well as the heart.

A doctor may request biopsy if imaging scans reveal a possible tumor in the lungs or stomach. During the procedure, doctors take a small sample of the fluid or tumor for lab analysis. The results can confirm a mesothelioma diagnosis, and indicate the best treatment plan.

There are many types of mesothelioma treatment, including chemotherapy, surgery and immunotherapy. Most doctors rely on a combination of these methods. Participating in clinical trials for new mesothelioma treatment may also be beneficial for patients. Patients can learn more about the trials by consulting a mesothelioma expert who has treated mesothelioma.
