Mesothelioma and Asbestos

Asbestos is a mineral that occurs naturally in the form of thin, long fibers. People who are exposed to asbestos regularly are at risk of developing mesothelioma or other types of lung diseases.

The symptoms of these diseases may not be evident for a long time after exposure to asbestos. Different asbestos types can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a type of cancer that affects the lung's outer the lining (pleura). It is the most frequent form of mesothelioma and is responsible for 70 to 79% of all diagnosed cases. People with this condition experience pain in the chest and shortness of breath, and they may feel the sensation of weight in the chest.

Exposure to asbestos, a class of minerals made of microscopic fibers, usually causes this kind of cancer. These fibers, when inhaled cause irritation and DNA mutations. Pleura is the lining of both the chest cavity as well as the lungs, and so irritations can also affect the heart. Mesothelioma typically doesn't manifest until 30 to 50 year after exposure.

Shortness of breath and chest pain are the most frequently reported symptoms. Some patients may also suffer from chest tightness or coughing. They may also experience difficulty breathing. Patients with this type of cancer typically have a history of exposure to asbestos in the workplace. The most common jobs that put people at risk of developing pleural mesothelioma are manufacturing, construction and shipbuilding. Individuals who have served in the military are at greater risk due to the frequent use of asbestos in Navy vessels and bunkers in the Army.

The TNM (tumors lymph nodes and metastases staging system) is the most popular staging system used to treat pleural adenocarcinoma. The stage a patient is in when they are diagnosed will assist their doctor in determining the most appropriate treatment plan for them. For instance, patients suffering from mesothelioma that is pleural in stage three or four have a less favorable prognosis than those in lower stages. Mesothelioma in stage four is usually spread to the liver, diaphragm or even a person's heart. This can make it more difficult to treat and increase the likelihood of complications for the patient.

Peritoneal Mesothelioma

Unlike 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 like the intestines and liver. Similar to pleural mesothelioma, exposure to asbestos is the reason for peritoneal msothelioma. The disease is less prevalent than pleural mesothelioma, and only about 300-500 cases diagnosed each year.

Like pleural mesothelioma, symptoms can take years to show. The majority of patients experience abdominal pain and abdominal swelling. The symptoms of this kind of mesothelioma can also include nausea as well as weight loss and fever. Many of these symptoms are similar to those experienced by digestive issues, which could cause incorrect diagnosis.

Generally speaking, doctors can detect mesothelioma through an extensive health history and physical exam. They can also use imaging tests such as X-rays, CT scans and PET/CT scans to detect mesothelioma. These tests can identify tumors as well as other signs of cancer which aren't evident on X-rays.

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 and whether the tumor has spread.

Asbestos exposure is the most important risk factor. People who have worked in jobs which require asbestos, like plumbing, manufacturing, electrical work or construction, are at greater risk of developing the disease. Even if a person isn't employed in one of these areas however, they may still be exposed through family members and other sources. Therefore, anyone who is concerned that they might be at risk should talk to an expert. A mesothelioma expert can help those with a history with asbestos to learn more about their risk.

Risk Factors

asbestos claim is the primary mesothelioma-related risk factor. It is responsible for as much as the 80% of cases. Exposure to asbestos can occur due to work, military service, or by living with someone who is exposed to Asbestos Legal or was previously exposed to doing so. Asbestos particles are inhaled by those who are exposed to asbestos. The particles cause irritation to the linings of the lungs, causing cancerous cells to grow in the mesothelium. After exposure to asbestos, mesothelioma may be diagnosed between 15 and 60 years.

Other risk factors include smoking, genetics and the advancing age. People in their 40s or 50s are more at risk of developing mesothelioma compared to those who are younger or older. It is because mesothelioma generally takes 20 to 60 years from the first exposure before the first signs of cancer appear. It is important to note, too, that mesothelioma could develop in people who have been exposed to asbestos without having been directly exposed to it. This is known as indirect or secondary asbestos exposure, and is just as harmful as direct asbestos exposure.

Smoking increases the chance of mesothelioma since it damages mesothelium. It also makes it more susceptible. Furthermore, mesothelioma is exacerbated by certain illnesses like pneumonia and asbestosis. Men are more likely to develop mesothelioma than women. This is due to men being more likely to work with asbestos and have a longer period of exposure than women. Men are also more likely to have lived with someone who been exposed to asbestos, and to carry asbestos fibers on their clothing. Women tend to be less exposed to asbestos, and they are less likely to carry asbestos on their clothes.

Diagnosis

It is difficult to diagnose mesothelioma due to its symptoms being often similar to other diseases. Due to this, patients are sometimes wrongly diagnosed.

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

Other diagnostic tests include a magnetic resonance scan or MRI test, which uses radio waves and magnets to create a series detailed images of inside the body. A surgical biopsy is yet another method doctors use to diagnose mesothelioma. A surgical biopsy is when doctors take a small amount of tissue from the peritoneum or pleura to conduct further tests. A pathologist then examines the tissue with a magnifying glass to determine if it is a cancerous cells.

The type of mesothelial cells involved as well as the benign or malignant nature of those cells, as well as the location and stage of the tumour, are used to categorize the disease. Some types of mesothelioma have a higher risk of metastasizing or spreading and it's crucial to establish a clear diagnosis so doctors can treat it prior to it becoming out-of-control.

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

Treatment

A diagnosis of mesothelioma can be frightening. It is crucial to remember, however, that cancer can be treated especially at its early stages. A lot of people suffering from mesothelioma be afflicted for a long time without expanding.

Exposure to asbestos may cause mesothelioma through a variety of ways. Asbestos fibers, which are tiny enough to be felt or seen by naked eyes are able to become airborne, causing irritation to the lung's lining (pleura). Over time, the irritation causes the formation of scar tissue which causes changes in the cell structure that eventually develop into tumors.

The pleura covers the lungs and heart and also the abdomen. Mesothelium is composed of cells that react when exposed to asbestos. They cause inflammation to the tissue and cause it to scar. Overtime, these changes result in the growth of malignant mesothelioma cancers.

Breathing problems, chest pain or fluid accumulation on the lungs are all symptoms of pleural msothelioma. In rare cases the cancer may grow to the tissues surrounding the heart and reproductive organs.

If imaging scans show an area of concern in the stomach or lungs doctors will recommend a biopsies. The procedure involves the removal of a small amount of fluid or tumor for laboratory testing. The results will confirm the diagnosis of mesothelioma and indicate the best treatment plan.

There are several types of mesothelioma treatments, including chemotherapy, surgery and immunotherapy. Most doctors utilize the combination of these treatments. Participating in clinical trials for new mesothelioma treatment may also be beneficial for patients. To learn more, patients should consult a mesothelioma specialist who has experience treating the condition.
