Mesothelioma and Asbestos

Asbestos is a naturally occurring mineral that is made up of thin, long fibres. People who are regularly exposed to asbestos are at risk of developing lung diseases, such as mesothelioma.

It may take decades before symptoms begin to manifest after exposure to asbestos. Different types of asbestos may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer that occurs in the outer lung the lining (pleura). It is the most frequent form of mesothelioma and is responsible for 70 to 79% all diagnosed cases. The condition can cause chest pain, shortness of breathe and a feeling heaviness.





This kind of cancer is often caused by exposure to asbestos which is a cluster of minerals composed of microscopic fibers. The fibers, when inhaled cause irritation and DNA mutations. Pleura surrounds both the chest cavity and the lungs, which means that irritations can also affect the heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

Chest pain and shortness breath are the most common symptoms. Some patients may also feel tightness in their chest and coughing, or breathing difficulties. Patients with this type of cancer typically have a history of exposure to asbestos in the workplace. Construction, manufacturing and shipbuilding are the most frequent occupations which put people at risk danger of developing pleural melanoma. People who served in the military are at a higher risk due to the frequent use of asbestos in Navy vessels and bunkers for the Army.

The most commonly used staging method for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage the patient is in at the time of diagnosis will help determine the treatment plan they should follow. Patients suffering from pleural mesothelioma who is in stage three or stage four will suffer a more negative outlook than those in a lower stage. Stage four mesothelioma can spread to the heart, liver or diaphragm. This could make the cancer more difficult to treat, and increase the chances of complications for the patient.

Peritoneal Mesothelioma

Contrary to pleural cancer which is found in the lining of the lung the peritoneal cancer is a result of a membrane that covers the abdominal cavity, including organs like the liver and intestines. Like pleural mesothelioma, peritoneal mesothelioma can be caused by asbestos exposure. It is estimated that only 300-500 cases are diagnosed annually which is lower than pleural asbestosis.

As with pleural asbestosis symptoms can take several years to show. The majority of patients are afflicted with abdominal pain as well as abdominal swelling. This kind of mesothelioma can cause nausea, weight loss, and fever. A lot of these symptoms are similar to symptoms of gastrointestinal issues, which can lead to misdiagnosis.

Doctors can identify mesothelioma by examining the patient's medical history and conducting a physical exam. Imaging tests like X-rays and CT scans can be used to identify mesothelioma. These tests can reveal cancerous tumors or other signs of cancer that aren't apparent on an X-ray.

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 as well as whether the cancer has spread.

The most important mesothelioma-related risk factor is exposure to asbestos. People who have worked in jobs that involve asbestos, such as plumbing manufacturing, electrical work, or construction, are at greater risk of developing the disease. Even if someone isn't employed in one of these fields they could be exposed to asbestos through family members or other sources. Anyone who suspects that they may be at risk should speak with a doctor. A mesothelioma expert can help those who have a previous history of asbestos to find out more about their risk.

Risk omaha asbestos law firm is the primary risk factor in mesothelioma. It accounts for up to the 80% of cases. Exposure to asbestos may occur through military service, work, or living with people who have worked with asbestos. Asbestos particles can be inhaled by those who are exposed to asbestos. These particles irritate the linings of the abdomen, which causes cancerous cells to grow in the mesothelium. Following exposure to asbestos mesothelioma can occur between 15 and 60 years.

Other risk factors include smoking, genetics and the advancing age. People in their 40s and 50s are at greater 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 to asbestos before cancer symptoms appear. It is also important to know that mesothelioma is a possibility in those who were exposed to asbestos but did not work with it directly. This is referred to as secondary or indirect asbestos exposure. It can be as dangerous as direct asbestos exposure.

Smoking increases the risk of mesothelioma, because it damages the mesothelium. It also makes it more prone to. Furthermore, mesothelioma is caused by certain illnesses, such as asbestosis and pneumonia. Men are more likely to develop mesothelioma than women. This is due to men being more likely to be exposed to asbestos and endure a more exposure than women. Also, men are more likely to live with someone who has was exposed to asbestos and bring asbestos fibers that have escaped home on their clothes. Women tend to be less in contact with asbestos, and they don't usually carry asbestos on their clothes.

Diagnosis

Mesothelioma is a difficult cancer to diagnose because the symptoms can be similar to other conditions. This could lead to patients being misdiagnosed.

NYU Langone doctors will perform a physical examination and record the patient's medical background including asbestos exposure. Doctors will also order an CT scan or chest X-ray to check for abnormalities, lumps and evidence of asbestos exposure. 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, which makes use of radio waves and magnets to create detailed images of the interior of the body. A surgical biopsy is a different way for doctors to diagnose mesothelioma. When a biopsy is performed doctors will remove a small piece of tissue from the pleura or the peritoneum, to be further examined. A pathologist will then look at the tissue with a magnifying lens to determine whether it contains cancerous cell.

Mesothelioma is classified according to the mesothelial type involved, whether the cells are malignant or benign, and the location of the tumor, its type, and the stage of the tumor. Certain types of mesothelioma are more likely to grow or spread, so it is important to have a clear diagnosis so that doctors can treat the disease before it becomes out of control.

Doctors may also conduct laboratory tests on a tumor to find specific genes, proteins, or other factors that help them understand the characteristics of cancer and plan treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be terrifying. It is crucial to remember that cancer can be treated especially at its early stages. Many patients with mesothelioma be afflicted for a long time, without spreading.

Asbestos exposure can trigger mesothelioma via a variety of mechanisms. Asbestos fibres, too small to be felt or observed with the naked eyes, can become airborne and irritate the lining of the lung (pleura). Over time, the irritation leads to the formation of scar tissue, which eventually lead to tumors.

The pleura surrounds the lungs and the heart and the abdomen. Mesothelium is made up of cells that react to asbestos and cause it to enflame and create scar tissue. Overtime, these changes lead to the development of malignant mesothelioma tumors.

A shortness of breath, chest pain or fluid accumulation on the lungs are all indications of pleural msothelioma. In rare cases the cancer may be spread to the tissues around the heart and reproductive organs.

If scans of imaging reveal a possible mass in the stomach or lungs doctors will recommend biopsies. During the procedure, doctors will remove a small sample of the fluid or tumor for lab analysis. The results can confirm a mesothelioma diagnosis, and determine the best treatment option.

There are many types of mesothelioma treatments, including surgery, chemotherapy and immunotherapy. Most doctors utilize the combination of these treatments. Participating in clinical trials of mesothelioma treatments may be beneficial to patients. To find out more, patients should speak to a mesothelioma specialist who has experience treating the condition.
