There's A Reason Why The Most Common Mesothelioma And Asbestos Debate Actually Isn't As Black And White As You Might Think
Mesothelioma and Asbestos

Asbestos is a natural mineral that is found in long, thin fibres. Workers who are regularly exposed to asbestos are at risk of developing lung diseases like mesothelioma.

It could take a long time for symptoms to show up after asbestos exposure. 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 is responsible for 70 to 79% of diagnosed cases. Patients with this disease suffer from chest pain and breathlessness and may experience the sensation of weight in the chest.

This type of cancer often caused by exposure to asbestos, which is a grouping of minerals composed of microscopic fibers. When inhaled, these fibers cling to the lungs and cause irritation that causes scarring and DNA mutations. The pleura surrounds the lungs and chest cavity This means that these irritations can affect both the lungs and a person's heart. Mesothelioma symptoms typically don't show until 30 to 50 years after exposure.

The most frequent symptoms of pleural mesothelioma include chest discomfort and shortness of breath. Patients may also experience coughing, difficulty breathing or chest tightness. People who suffer from this cancer usually have a history of exposure to asbestos in the workplace. Manufacturing, construction and shipbuilding are among the most prevalent occupations that put people at high risk of developing pleural mesothelioma. Individuals who have been in the military are at a higher risk because of the extensive asbestos use in Navy vessels and bunkers for the army.

The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most common staging system for the pleural cancer. The stage that a patient is at when they are diagnosed will help their doctor determine the most appropriate treatment plan for them. Patients who have pleural mesothelioma which is in stage three or four will have a less favorable outlook than those who are in a less advanced stage. Stage four mesothelioma can develop into the liver, heart or diaphragm. This can make the cancer more difficult to treat, and increase the chances of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which develops in the lung lining, peritoneal mesothelioma forms in the peritoneum - it is a membrane that lines the abdominal cavity as well as organs like the intestines and liver. Like pleural mesothelioma, asbestos exposure is the cause of peritoneal msothelioma. The disease is less common than pleural mesothelioma, and around 300-500 cases being diagnosed each year.

As with pleural asbestosis, symptoms can take a long time to manifest. Patients usually experience abdominal pain, and may also have a lump in their abdomen. The symptoms of this type of mesothelioma could also include nausea, weight loss and fever. Many of these symptoms can be misinterpreted as gastrointestinal issues which can lead to a misdiagnosis.

asbestos lawyers can detect mesothelioma by reviewing the medical history of the patient and performing a physical exam. Imaging tests like X-rays and CT scans are a way to identify mesothelioma. These tests can identify tumors and other cancer signs that are not evident on X-rays.

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

The most significant mesothelioma risk factor is exposure to asbestos. People who have been in occupations that involve asbestos, like plumbing electrical work, manufacturing or construction, are at a higher risk of developing the disease. However, even if individuals do not work in these fields they could be exposed to asbestos through family members or through other sources. This is why anyone who is concerned that they might be at risk should speak to an expert. A mesothelioma specialist can help those with a history with asbestos to learn more about their risk.

Risk Factors

Asbestos is the main risk factor in mesothelioma. It is responsible for up to 80percent of cases. Exposure to asbestos may occur due to work, military service or through living with a person who is exposed to asbestos or used to do the same. Asbestos particles can be inhaled by those who are exposed to asbestos. They can cause irritation to the linings of the abdomen and cause cancerous cells to develop in the mesothelium. Mesothelioma may take between 15 and 60 years to develop after exposure to asbestos.


Other risk factors include smoking, genetics and the advancing age. People in their 40s and 50s are more likely be diagnosed with mesothelioma compared to those who are younger or older. It takes mesothelioma between 20 and 60 years to show signs of cancer after the first exposure. It is important to remember, too, that mesothelioma may occur in those who have been exposed to asbestos without having worked with it directly. This is called secondary or indirect exposure to asbestos and it could be as hazardous as direct exposure.

Smoking increases a person's chances of developing mesothelioma since it damages the mesothelium and makes it more vulnerable to asbestos. Mesothelioma can also be aggravated by certain diseases, such as asbestosis and pneumonia. It is also important to remember that mesothelioma is more common in males than females. This is due to men being more likely to be exposed to asbestos and endure a an extended period of exposure than women. Additionally, men are more likely to live with someone who has was exposed to asbestos and bring stray asbestos fibers home on their clothing. Women are less likely to come into contact with asbestos and rarely carry asbestos on their clothes.

Diagnosis

Mesothelioma is a difficult disease to identify because the symptoms often resemble other diseases. Due to this, patients are sometimes 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, including asbestos exposure. Doctors will also recommend an CT scan or chest X-ray 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 imaging or MRI test, that uses magnets and radio waves to create a series detailed images of the inside of the body. Another way for doctors to detect mesothelioma is by performing an operation called a biopsy. During a surgery biopsy, doctors remove a tiny piece of tissue from the pleura or the peritoneum to be examined further. A pathologist is then able to examine the tissue under a microscope to see if it contains cancerous cells.

Mesothelioma can be classified based on the type of mesothelial cells involved, whether these cells are malignant or benign and also the location, type, and stage of the tumor. Certain types of mesothelioma are more likely to grow or spread which is why it is crucial to get a definite diagnosis so doctors can treat the disease before it gets out of control.

Doctors may also conduct laboratory tests on tumors to determine specific proteins, genes and other factors that can help them describe the characteristics of the cancer and determine a treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be frightening. It is important to remember that cancer can be treated, especially at its early stages. Many patients with mesothelioma survive for years with the disease without it spreading to other areas of their body.

Exposure to asbestos can trigger mesothelioma via a variety of mechanisms. Asbestos fibers, which are tiny enough to be felt or viewed with the naked eyes, can become airborne and irritate the lung's lining (pleura). In time the irritation can lead to the formation of scar tissues that eventually result in tumors.

The Pleura is a protective layer that protects the abdomen, heart, and lungs. Mesothelium consists of cells that respond when exposed to asbestos. They inflame the tissue and cause it to scar. In time, these changes can lead to the development of malignant mesothelioma tumors.

The signs of pleural mesothelioma can include shortness of breath and chest pain, or an accumulation of fluid on the lung (pleural effusion). In rare cases, cancer can spread into the tissues surrounding the reproductive organs and heart.

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

There are a variety of treatment for mesothelioma such as chemotherapy and surgery. Most doctors use combinations of these treatments. Patients can also benefit by taking part in a clinical trial of new mesothelioma therapies. To learn more about the trials, patients should speak with mesothelioma specialists who have expertise in treating the condition.
