Introduction To The Intermediate Guide Towards Mesothelioma And Asbestos
Mesothelioma and Asbestos

Asbestos is a natural mineral that is made up of long, thin fibres. Workers who are exposed asbestos on a regular basis are at risk of developing mesothelioma as well as other lung diseases of different types.

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

Pleural Mesothelioma

Pleural mesothelioma can be found in the lung's outer lining, or the pleura. It is the most common form of mesothelioma and is responsible for 70 to 79% of diagnosed cases. Patients with this disease experience pain in the chest and breathlessness and may experience a sensation of heaviness in the chest.

This type of cancer usually caused by exposure to asbestos which is a grouping of minerals made up of microscopic fibres. Once inhaled, the fibers are absorbed into the lung and cause irritation that causes scarring and DNA mutations. Pleura surrounds both the chest cavity as well as the lungs, and so irritations can also affect the heart. Mesothelioma usually doesn't show symptoms until 30 to 50 year after exposure.

The most commonly reported symptoms of pleural melanoma are chest pain and shortness of breath. Some patients have coughing problems, trouble breathing, or chest tightness. Patients with this type of cancer typically have an history of exposure to asbestos in the workplace. The most common jobs that expose workers to the risk of developing pleural cancer are manufacturing, construction, and shipbuilding. People who were in the military are at greater risk due the extensive use asbestos in Navy vessels and bunkers in the Army.

The most popular staging method for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage a patient is in at the time of diagnosis will help determine the treatment plan they should receive. Patients suffering from pleural mesothelioma who is in stage three or stage four will have a less favorable prognosis than those who are in a less advanced stage. Stage four mesothelioma may develop into the heart, liver or diaphragm. This can make it more difficult to treat and increase the chance of complications for patients.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which develops in the lung lining, peritoneal mesothelioma develops in the peritoneum - a membrane that lines the abdominal cavity and organs such as the intestines and liver. Similar to pleural mesothelioma and peritoneal mesothelioma is caused by asbestos exposure. The disease is less prevalent than pleural mesothelioma, and only about 300-500 cases diagnosed each year.

As with pleural asbestosis symptoms can take several years to manifest. Patients typically suffer from abdominal pain and may also have a lump in their abdomen. This type of mesothelioma may cause nausea, weight loss and fever. appleton asbestos attorneys of these symptoms are similar to those experienced by digestive problems, which can lead to confusion in diagnosis.

Generally, doctors can find mesothelioma by conducting a thorough health history and physical exam. Imaging tests like X-rays and CT scans are a way to detect mesothelioma. These tests can reveal tumors and other indications of cancer that aren't apparent on an X-ray.

These tests enable doctors to diagnose mesothelioma, identify the stage and recommend treatment options. The stage is determined by the kind of cell and if the cancer has spread.


The most important risk factor for mesothelioma is asbestos exposure. People who have worked in asbestos-containing jobs, such as plumbing or electrical work, or in manufacturing and construction, are more likely to develop the disease. Even if someone does not work in one of these areas however, they may still be exposed to asbestos through family members and other sources. This is why anyone who believes they could be at risk should speak to a doctor. A mesothelioma specialist can help those who have had a previous history of asbestos to find out more about their risk.

Risk Factors

Asbestos exposure is the primary risk factor for mesothelioma, making up as much as 80 percent of cases. Exposure to asbestos can happen due to work, military service or through living with a person who works with asbestos or was previously exposed to doing the same. Asbestos particles can be breathed in by people who are exposed to it. These particles irritate the linings, causing cancerous cells to develop in the mesothelium. After exposure to asbestos mesothelioma can be diagnosed between 15 and 60 year.

Other risk factors include genetics, smoking and age. People in their 40s and 50s are more likely develop mesothelioma than those who are younger or older. It takes mesothelioma 20-60 years to show signs of cancer after the first exposure. It is also important to know that mesothelioma is a possibility in people who have been exposed to asbestos but didn't deal with it directly. This is referred to as secondary or indirect asbestos exposure and can be just as harmful as direct asbestos exposure.

Smoking increases a person's chances of developing mesothelioma due to the fact that it causes mesothelium damage and makes it more susceptible to asbestos. In addition, mesothelioma may be worsened by certain diseases like asbestosis and pneumonia. 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 live with someone who had asbestos exposure and bring asbestos fibers from their workplace on their clothes. Women are less likely to come exposed to asbestos and they don't usually carry asbestos on their clothes.

Diagnosis

It is difficult to diagnose mesothelioma since its symptoms are frequently similar to other illnesses. This can result in patients being incorrectly diagnosed.

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

Other diagnostic tests include an echocardiogram which examines the heart and blood vessels as well as a magnetic resonance imaging, or MRI test that uses magnets and radio waves to make a series of precise images of the inside of the body. A surgical biopsy is another way for doctors to diagnose mesothelioma. A surgical biopsy is when doctors remove a small piece 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 is contaminated with cancerous cells.

The mesothelial type involved, the malignant or benign nature of these cells, as well as the location and stage of the tumor, are used to categorize the disease. Certain mesothelioma types 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 prior to it becoming out-of-control.

Doctors may also conduct laboratory tests on tumors to identify specific proteins, genes or other factors that can aid in describing cancer characteristics and plan treatment. These results are known as staging.

Treatment

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

Exposure to asbestos can trigger mesothelioma via various mechanisms. Asbestos fibers that are tiny enough to be felt or viewed through the naked eye, can become airborne, causing irritation to the lung's lining (pleura). As time passes irritation leads to formation of scar tissue which can cause changes in the structure of cells which eventually lead to tumors.

The pleura covers the lungs and heart, as well as the abdomen. Mesothelium is composed of cells that respond when exposed to asbestos. They cause inflammation of the tissue and cause it to scar. In time, these changes can result in the growth of malignant mesothelioma tumors.

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

A doctor will request biopsy if scans reveal a possible tumor in the lungs or stomach. In the course of the procedure, doctors remove small amounts of fluid or tumor to allow for tests in the laboratory. The results can confirm the diagnosis of mesothelioma and help determine the most effective treatment plan.

There are several types of mesothelioma treatments, which include chemotherapy, surgery, and immunotherapy. The majority of doctors employ the combination of these treatments. Participating in clinical trials for mesothelioma treatments may be beneficial for patients. To find out more, patients should consult a mesothelioma specialist who has had experience treating the disease.
