Mesothelioma and Asbestos
Asbestos is a naturally occurring mineral that is found in long, thin fibres. People who are regularly exposed to asbestos are at risk of developing lung diseases such as mesothelioma.
The symptoms of these diseases might not show up for decades after exposure to asbestos. Different asbestos types can cause different symptoms.
Pleural Mesothelioma
Pleural mesothelioma occurs in the lung's outer lining, or pleura. It is the most prevalent mesothelioma form and is responsible for 70 to 79% all diagnosed cases. The condition can cause chest pain, breath shortness, and a feeling of weightiness.
Exposure to asbestos, a group of minerals comprised of microscopic fibers causes this type of cancer. Once inhaled, the fibers stick inside the lungs and cause irritation that causes scarring and DNA mutations. The pleura surrounds the lungs and chest cavity and therefore, these irritations could affect both the lungs as well as the heart of a person. Mesothelioma usually doesn't show symptoms until 30 to 50 years after exposure.
The most frequent symptoms of pleural melanoma are chest pain and breath shortness. Patients may also experience coughing, difficulty breathing or chest tightness. People with this cancer have a past that includes
asbestos legal exposure at work. Construction, manufacturing, and shipbuilding are the most common occupations that put people at high risk of developing pleural mesothelioma. People who have served in the military could be at risk due to the frequent asbestos use in Navy ships and bunkers for the army.
The TNM (tumors lymph nodes and metastases staging system) is the most commonly used staging system used to treat the pleural adenocarcinoma. The stage a patient has upon diagnosis will help their doctor determine the best treatment plan for them. For instance, patients who have a pleural mesothelioma in stage three or four have a worse prognosis than patients with a lower stage. Stage four mesothelioma is often spread to the diaphragm, liver and/or a person's heart. This makes the cancer more difficult to treat, and increase the risk of complications for the patient.
Peritoneal Mesothelioma
In contrast to pleural cancer, which forms in the lining of the lung, peritoneal cancer develops in a membrane that covers the abdominal cavity, which includes organs like the intestines and liver. As with pleural mesothelioma
asbestos legal exposure is the primary cause of peritoneal msothelioma. The disease is less prevalent than pleural mesothelioma. There are just 300-500 cases being diagnosed each year.
Like pleural mesothelioma, symptoms may take years to appear. The majority of patients are afflicted with abdominal pain as well as abdominal swelling. The symptoms of this type of mesothelioma may also include nausea or weight loss, as well as fever. Many of these symptoms could be misinterpreted as digestive issues and can lead to a false diagnosis.
Generally, doctors can find mesothelioma after a thorough health history and physical exam. They can also use imaging tests like Xrays, CT scans and PET/CT scans to detect mesothelioma. These tests can reveal tumors, as well as other signs of cancer that aren't visible on X-rays.
These test results allow doctors to diagnose mesothelioma, determine the stage and suggest treatment options. The stage of the disease is determined based on the cell type and whether or not the tumor has spread to other regions of the body.
The most significant mesothelioma risk factor is asbestos exposure. People who have been in occupations which require asbestos, such as plumbing, manufacturing, electrical work or construction, are at a higher risk of developing the disease. However, even if individuals do not work in these fields they may be exposed to asbestos through relatives or other sources. Anyone who suspects that they are at risk should talk to an expert. If they have a history of asbestos exposure, a mesothelioma specialist can assist them in finding out more about the risk.
Risk Factors
Asbestos is the primary risk factor in mesothelioma. It is responsible for as much as 80% of all cases. Exposure to asbestos can occur through work, military service or through living with a person who works with
asbestos litigation or used to do so. When exposed to asbestos, the particles are able to be inhaled into abdomen and lungs. These particles can cause irritation to the linings of the lungs, causing cancerous cells to develop in the mesothelium. Mesothelioma may take between 15 and 60 years to develop following exposure to asbestos.
Other risk factors include smoking, genetics, and the advancing age. People in their 40s and 50s are more likely get mesothelioma than people younger or more senior. Mesothelioma can take between 20 and 60 years to manifest cancer symptoms after the first exposure. It is important to remember, too, that mesothelioma can develop in people who have been exposed to asbestos (

Smoking can increase the likelihood of developing mesothelioma due to the fact that it damages the mesothelium, which makes it more prone to asbestos. Mesothelioma can also be caused by certain illnesses, including asbestosis and pneumonia. Men are more likely to develop mesothelioma compared to women. Men are more likely than women to have been exposed to asbestos for a longer time and to work with it. Men are also more likely to have lived with someone who has worked with asbestos, and to carry asbestos fibers on their clothing. Women are less likely to come into exposure to asbestos and do not typically carry asbestos home on their clothing.
Diagnosis
Mesothelioma is a difficult cancer to diagnose because the symptoms can be similar to other conditions. Due to this, patients are sometimes wrongly diagnosed.
NYU Langone doctors will perform an examination of the body and document the patient's medical history, including
asbestos lawsuit exposure. Doctors will also order an CT scan or chest X-ray to look for lumps, abnormalities and evidence of asbestos exposure. These include plaques in the pleura, thickened pleura and calcium deposits.
Other diagnostic tests include a magnetic resonance image, or MRI test, which uses radio waves and magnets to produce a series of precise images of the inside of the body. A surgical biopsy is another way for doctors to diagnose mesothelioma. In a surgical biopsy doctors take a tiny piece of tissue from pleura or the peritoneum to be further examined. A pathologist can look at the tissue under microscopes to determine whether it contains cancerous cells.
Mesothelioma is classified according to the mesothelial type involved, whether those cells are malignant or benign, and the location of the tumor, the type, and the stage of the cancer. Some types of mesothelioma are more likely to grow or spread which is why it is crucial to have a clear diagnosis to ensure that doctors are able to treat the disease before it goes out of control.
Doctors can also perform laboratory tests on tumors to determine specific proteins, genes, or other factors which will help them identify cancer characteristics and determine the best treatment. These results are referred to as staging.
Treatment
A diagnosis of mesothelioma may be terrifying. But, it is crucial to remember that the disease is treatable, especially in its earlier stages. Many people with mesothelioma can endure the disease for many years without it spreading.
Asbestos exposure can cause mesothelioma by various mechanisms. Asbestos fibers, too small to be able to see or feel with the naked eye, can become airborne and irritate the lung's lining (pleura). Over time the irritation can lead to the formation of scar tissues that eventually result in tumors.
The pleura covers the lungs and the heart and also the abdomen. Mesothelium is composed of cells that react to asbestos which causes it to become inflamed and develop scar tissue. These changes can eventually cause mesothelioma cancers.
Shortness of breath, chest pain or fluid accumulation on the lungs are all symptoms of the pleural Msothelioma. In rare instances, the cancer can spread to the tissues surrounding the heart and reproductive organs.
If imaging scans show a possible mass in the lungs or stomach, a doctor will order biopsies. In the course of the procedure, doctors remove some of the fluid or tumor to allow for lab tests. The results can confirm the diagnosis of mesothelioma, and also determine the best treatment plan.
There are a variety of treatment for mesothelioma including chemotherapy and surgery. Most doctors utilize a combination of these treatments. Patients may also benefit from participating in a clinical study of new mesothelioma treatment. Patients can learn more about the trials by consulting a mesothelioma expert who has treated mesothelioma.
