Mesothelioma and Asbestos

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

The 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 is a cancer that affects the lung's outer the lining (pleura). It is the most frequent mesothelioma type and accounts for 70% to 79% all diagnosed cases. The condition can cause chest pain, shortness of breathe and a feeling of heavyness.

Exposure to asbestos, a group of minerals made of microscopic fibers causes this kind of cancer. The fibers, when inhaled cause irritation and DNA mutations. Pleura surrounds both the chest cavity and the lungs, and so irritations can also affect the heart. Mesothelioma is usually not symptomatic until 30 to 50 years after exposure.

The most frequent symptoms of pleural mesothelioma 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. Construction, manufacturing and shipbuilding are among the most prevalent occupations which put people at risk chance of developing pleural mesothelioma. People who have served in the military are at a higher risk due to the frequent use of asbestos in Navy vessels and army bunkers.

The most popular staging system for pleural mysothelioma has been the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage a patient is in at the time of diagnosis can help determine the treatment plan they should follow. Patients with pleural mesothelioma that is in stage three or four will suffer a more negative prognosis compared to those in a lower stage. Stage four mesothelioma can be spread to the heart, liver or diaphragm. This makes it more difficult to treat and increase the likelihood of complications for patients.

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 and organs like the intestines and the liver. As with pleural mesothelioma exposure to asbestos law is the reason for peritoneal msothelioma. Only 300-500 cases are diagnosed annually, which is less than pleural asbestosis.

As with pleural asbestosis, symptoms can take several years to manifest. Patients usually suffer from abdominal pain and may also have a lump in their abdomen. The symptoms of this kind of mesothelioma could also include nausea, weight loss and fever. Many of these symptoms are similar to those of gastrointestinal issues, which can cause confusion in diagnosis.

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

The results of these tests allow doctors to diagnose mesothelioma, identify the stage and suggest treatment options. Staging is determined based on the cell type and whether or not the tumor has spread to other areas of the body.

Asbestos exposure is the main risk factor. People who have worked in asbestos-containing jobs, such as plumbing or electrical work, or in construction and manufacturing, are more likely to develop the disease. However, even if individuals aren't employed in these fields they could be exposed to asbestos case through relatives or other sources. Therefore, anyone who suspects they may be at risk should speak to an expert. A mesothelioma expert can help those who have a previous history of asbestos to find out more about their risk.

Risk Factors

Asbestos is the primary risk factor for mesothelioma. It is responsible for as much as 80percent of cases. Exposure to asbestos can happen due to work, military service or through living with a person who works with asbestos or has previously done the same. Asbestos particles can be inhaled by people who are exposed to it. The particles cause irritation to the linings of the abdomen, which causes cancerous cells to grow in the mesothelium. Following exposure to asbestos mesothelioma can develop between 15 and 60 year.

Other risk factors include smoking, genetics and age. People in their 40s and 50s are more likely develop mesothelioma than those who are younger or older. This is because mesothelioma typically takes 20 to 60 years after the initial exposure to asbestos before the first signs of cancer appear. It is important to keep in mind that mesothelioma may be present in people who have been exposed to asbestos without having directly worked with it. This is called secondary or indirect exposure to asbestos. It can be just as dangerous as direct exposure.

Smoking increases the risk of developing mesothelioma due to the fact that it damages the mesothelium, which makes it more susceptible to asbestos. Mesothelioma is also aggravated by certain illnesses such as 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 longer periods of time and work with it. Men are also more likely to have lived with someone who been exposed to Asbestos Case, and to have asbestos-containing fibers on their clothing. Women are less likely to come exposed to asbestos, and don't typically carry asbestos on their clothing.

Diagnosis

It is difficult to diagnose mesothelioma due to its symptoms being frequently similar to other illnesses. This could lead to patients being misdiagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform an examination and write notes on the medical history of a patient which includes asbestos exposure. Doctors can also request an X-ray chest or CT scan to look for lumps and other abnormalities, and also to look for evidence of past asbestos exposure like plaques on the pleura (thickened pleura with calcium deposits) and the accumulation of fluid between the lung and chest wall (known as the pleural effusion).

Other diagnostic tests include a magnetic resonance image or MRI test, which makes use of radio waves and magnets in order to create a series of detailed images of the inside of the body. Another way for doctors to detect mesothelioma is to perform an operation called a biopsy. During a surgery biopsy, doctors remove a tiny piece of tissue from the pleura or the peritoneum to be tested further. A pathologist can then examine the tissue with microscopes to determine whether it has cancerous cells.

The type of mesothelial cells involved as well as the benign or malignant nature of the cells as well as the location and stage of the tumor, are used to classify the disease. Certain types of mesothelioma are more likely to develop metastasis or spread and spread, therefore it is essential to have a clear diagnosis to ensure that doctors are able to treat the disease before it goes out of control.

Doctors may also conduct laboratory tests on tumors in order to determine specific proteins, genes or other elements that will help them identify the characteristics of cancer and plan treatment. These results are referred to as staging.

Treatment

A mesothelioma diagnose can be frightening. It is important to keep in mind that cancer can be treated particularly in its early stages. Many patients with mesothelioma survive for many years with the disease, without spreading to other areas of their body.

Asbestos exposure can trigger mesothelioma via a variety of mechanisms. Asbestos fibers, which are too small to be able to see or feel by the naked eye can become airborne and irritate the lung's lining (pleura). Over time irritation leads to formation of scar tissue which leads to changes in the cell structure that eventually develop into tumors.

The pleura is a protective covering that protects the lungs, heart and abdomen. Mesothelium is made up of cells that respond when exposed to asbestos claim. They cause inflammation of the tissue and cause it to become scarred. These changes can result in malignant mesothelioma tumors.

Symptoms of pleural mesothelioma include shortness of breath and chest pain, or a buildup of fluid in the lungs (pleural effusion). In rare cases cancer may spread to the tissues that surround the reproductive organs and the heart.

If imaging scans show an area of concern in the lungs or stomach the doctor will request biopsies. During the procedure, doctors remove a small sample of the fluid or tumor for lab tests. The results can confirm a mesothelioma diagnosis, and provide the best treatment plan.

There are many types of treatment for mesothelioma including surgery and chemotherapy. Most doctors use a combination of these treatments. Enrolling in clinical trials of mesothelioma treatments may be beneficial to patients. To find out more, patients should consult mesothelioma experts who have expertise in treating the condition.
