Mesothelioma and Asbestos

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

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

Pleural Mesothelioma

Pleural mesothelioma is a cancer that occurs in the lung's outer the lining (pleura). It is the most common form of mesothelioma and accounts for 70% to 79% of diagnosed cases. Patients with this disease feel chest pain and breathlessness and may also feel an ache or heaviness in the chest.

Exposure to asbestos, a group of minerals comprised of microscopic fibers, usually causes this kind of cancer. When inhaled, these fibers are absorbed into the lung and cause irritation which causes scarring and DNA mutations. Pleura surrounds both the chest cavity and the lungs, and so irritations can also affect the heart. Mesothelioma symptoms typically don't show until 30 to 50 years after exposure.

Chest pain and shortness breath are the most frequently reported symptoms. Patients may also experience chest tightness, coughing or difficulty breathing. Patients with this type of cancer typically have a history of exposure to asbestos in the workplace. The most common jobs that expose workers to the risk of developing pleural cancer are construction, manufacturing and shipbuilding. Individuals who have been in the military are at risk due to the frequent use of asbestos in Navy ships and bunkers used by the army.

The most common staging method for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage a patient has when they are diagnosed will assist their doctor in determining the most appropriate treatment plan for them. Patients suffering from pleural mesothelioma who is in stage three or stage four will have a less favorable outlook than those who are in a lower stage. Stage four mesothelioma often spreads to the diaphragm, liver and/or a person's heart. This could make the cancer more difficult to treat and increase the chance of complications for patients.

Peritoneal Mesothelioma

In contrast to pleural cancer, that develops in the lining of the lung the peritoneal cancer is a result of a membrane that surrounds the abdominal cavity, including organs like the intestines and the liver. Similar to pleural mesothelioma mesothelioma is caused by asbestos exposure. The disease is less prevalent than pleural mesothelioma. There are around 300-500 cases being diagnosed each year.

As with pleural asbestosis symptoms can take years to show. Most patients are afflicted with abdominal pain as well as abdominal swelling. Symptoms of this type of mesothelioma can also include nausea or weight loss, as well as fever. A lot of these symptoms can be misinterpreted as digestive issues, leading to a mistaken diagnosis.

The doctors can detect mesothelioma through looking over the medical history of the patient and conducting a physical exam. Imaging tests like X-rays or CT scans are a way to detect mesothelioma. These tests can detect tumors and other signs of cancer which aren't visible on X-rays.

These tests enable doctors to diagnose mesothelioma and determine the stage of the disease and suggest treatment options. The staging is determined by the cell type and whether or whether the tumor has spread to other regions of the body.

Asbestos exposure is the biggest risk factor. People who have been in occupations which require asbestos, like plumbing, manufacturing, electrical work, or construction, are at greater risk of developing the disease. Even if an individual does not work in one of these areas they could still be exposed through family members and other sources. This is why anyone who suspects they may be at risk should speak to an experienced doctor. A mesothelioma specialist can help those who have had a experience with asbestos to understand more about their risk.

Risk Factors

Asbestos is the most significant risk factor for mesothelioma. It accounts for up to the 80% of cases. Exposure to asbestos may occur through work, military service, or by living with someone who works with asbestos or used to do the same. Asbestos particles are inhaled by those who are exposed to it. The particles cause irritation to the linings of the abdomen, which causes cancerous cells to grow in the mesothelium. Mesothelioma can take between 15 and 60 years to develop after exposure to asbestos settlement.

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. This is because mesothelioma typically takes 20 to 60 years after the initial exposure to asbestos before cancer symptoms appear. It is also important to note that mesothelioma can develop in people who have been exposed to Asbestos Case but didn't work with it directly. This is known as secondary or indirect asbestos exposure and can be as hazardous as direct asbestos exposure.

Smoking increases the risk of developing mesothelioma since it causes mesothelium damage and makes it more vulnerable to asbestos compensation. Mesothelioma can also be caused by certain illnesses, including asbestosis and pneumonia. Men are more likely to develop mesothelioma than females. This is due to men being more likely to be exposed to asbestos and endure a more exposure than women. Men are also more likely to live with someone who has was exposed to asbestos and bring asbestos litigation fibers that have escaped home on their clothes. Women tend to have less contact with asbestos and don't typically carry asbestos home on their clothes.

Diagnosis

Mesothelioma is a difficult disease to recognize because the symptoms often resemble other diseases. This could lead to patients being incorrectly diagnosed.

The first step to diagnose mesothelioma is for NYU Langone doctors to perform an examination of the body and take notes on the medical history of a patient including asbestos exposure. Doctors may also request a CT scan or chest X-ray in order to look for lumps, abnormalities, and evidence of asbestos exposure. These include plaques on the pleura, pleura that are thickened and calcium deposits.

Other diagnostic tests include a magnetic resonance imaging, or MRI test, which makes use of radio waves and magnets in order to create a series of detailed images of inside the body. Another way for doctors to detect mesothelioma is through an operation called a biopsy. During a surgical biopsy, doctors take a small amount of tissue from the pleura or peritoneum to conduct further tests. A pathologist is then able to examine the tissue with microscopes to determine if it has cancerous cells.

Mesothelioma can be classified based on the type of mesothelial cells involved, whether the cells are benign or malignant and the location of the tumor, the type, and the stage of the tumor. Certain types of mesothelioma are more likely to develop metastasis or spread which is why it is crucial to establish a definitive diagnosis so that doctors can treat the disease before it becomes out of control.

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

Treatment

A mesothelioma diagnosis is an incredibly frightening prospect. But, it is crucial to remember that the disease is treatable, especially in its early stages. Many people with mesothelioma can live with the disease for a long time, without spreading.

Exposure to asbestos can trigger mesothelioma in many ways. Asbestos particles, which are too small to be able to see or feel through the naked eye, can become airborne and cause irritation to the lung's lining (pleura). Over time, the irritation leads to the formation of scar tissue, which eventually lead to tumors.

The pleura is a protective covering that protects the lungs, heart and abdomen. Mesothelium is made up of cells that react when exposed to asbestos. They inflame the tissue and cause it to become scarred. These changes can cause mesothelioma cancers.

Shortness of breath, chest discomfort, or the accumulation of fluid on the lungs are all signs of pleural Msothelioma. In rare instances, cancer can spread into the tissues surrounding the reproductive organs as well as the heart.

If imaging scans reveal an underlying mass in the stomach or lungs the doctor will request a biopsies. In the course of the procedure, doctors remove small amounts of fluid or tumor to allow for laboratory testing. The results can confirm a mesothelioma diagnosis, and indicate the most effective treatment plan.

There are a variety of mesothelioma treatments, including surgery, chemotherapy and immunotherapy. Most doctors utilize the combination of these methods. Participating in clinical trials for mesothelioma treatments may be beneficial for patients. Patients can find out more by speaking with a mesothelioma doctor who has treated mesothelioma.
