Mesothelioma and Asbestos

Asbestos is a mineral that naturally occurs in the form of thin, long fibers. People who are exposed to asbestos on a regular basis risk developing mesothelioma and other lung diseases of different types.

It may take decades for symptoms to show up after exposure to asbestos. Different asbestos types can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma, a form of cancer, that occurs in the outer lung lining (pleura). It is the most frequent mesothelioma type and accounts for 70% to 79% of diagnosed cases. Patients with this disease experience pain in the chest and breathlessness and may also feel the sensation of weight in the chest.

Exposure to asbestos, a family of minerals made of microscopic fibers causes this type of cancer. The fibers, when inhaled, cause irritation and DNA mutations. Pleura is the lining of both the chest cavity as well as the lungs, which means that irritations can also affect the heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most frequently reported symptoms. Patients may also experience difficulty breathing, or chest tightness. Patients with this cancer have a history that includes asbestos law exposure at work. The most prevalent jobs that put people at risk of developing pleural mesothelioma are manufacturing, construction and shipbuilding. People who have served in the military are at risk due to the widespread asbestos usage in Navy vessels and bunkers for the army.

The most common staging system for pleural mysothelioma has been the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage a patient is in when they are diagnosed will assist their doctor in determining the most effective treatment plan for them. For example, patients with a pleural mesothelioma in stage three or four have a less favorable prognosis than those with a lower stage. Stage four mesothelioma can be spread to the liver, heart or diaphragm. This can make it more difficult to treat and increases the likelihood of complications for the patient.

Peritoneal Mesothelioma

In contrast to pleural cancer, that develops in the lung's lining, peritoneal cancer develops in a membrane that surrounds the abdominal cavity, which includes organs such as the intestines and liver. Similar to pleural mesothelioma mesothelioma is triggered by asbestos exposure. The disease is less prevalent than pleural mesothelioma, with around 300-500 cases being diagnosed each year.

Like pleural mesothelioma, symptoms can take years to show. Typically, patients suffer from abdominal pain and an abdominal mass. The symptoms of this kind of mesothelioma could also include nausea as well as weight loss and fever. A lot of these symptoms are similar to symptoms of gastrointestinal issues, which can lead to incorrect diagnosis.

The doctors can detect mesothelioma through examining the patient's medical history and performing a physical exam. Imaging tests like X-rays or CT scans can be used to identify mesothelioma. These tests can reveal tumors and other signs of cancer which aren't evident on X-rays.

These test results enable doctors to identify mesothelioma, and determine the stage. They can also recommend treatment options. The stage is determined by the type of cell and whether the tumor has spread.

The most important mesothelioma risk factor is asbestos settlement exposure. People who have worked in Asbestos Case-containing occupations, like plumbing or electrical work, or in construction and manufacturing are more likely to develop the disease. Even if someone is not employed in any of these areas however, they may still be exposed through family members and other sources. This is why anyone who believes they could be at risk should speak to an experienced doctor. If they have any history of exposure to asbestos and mesothelioma is a concern, a specialist will help them find out more about the risk.

Risk Factors

Asbestos exposure is the main mesothelioma risk factor, accounting for up to 80 percent of cases. Exposure to asbestos can occur as a result of military service, work or living with those who worked with asbestos. When exposed to asbestos, small particles can be breathed into the lungs and abdomen. These particles irritate the linings of the abdomen, which causes cancerous cells to form in the mesothelium. After asbestos exposure mesothelioma can occur between 15 and 60 year.

Other risk factors include genetics, smoking and age. People in their 40s and 50s are more likely to be diagnosed with mesothelioma compared to those who are younger or older. Mesothelioma can take between 20 and 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 engage directly with it. This is known as indirect or secondary asbestos exposure. It can be as dangerous as direct asbestos attorney exposure.

Smoking increases the risk of mesothelioma, because it damages the mesothelium. It also makes it more prone to. In addition, mesothelioma may be worsened by certain diseases like pneumonia and asbestosis. It is also important to note that mesothelioma occurs more frequently in males than females. This is due to the fact that men are 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 was exposed to asbestos and bring stray asbestos fibers home on their clothing. Women are less likely to come into exposure to asbestos legal and don't typically carry asbestos around on their clothing.

Diagnosis

Mesothelioma is difficult to identify because the symptoms can be similar to other conditions. Because of this, victims are sometimes misdiagnosed.

The first step to diagnose mesothelioma is for NYU Langone doctors to perform a physical exam and take down a patient's medical history which includes asbestos exposure. Doctors can also request an X-ray of the chest or CT scan to detect lumps and other abnormalities as well as evidence of previous asbestos exposure like pleural plaques (thickened pleura with calcium deposits) and the buildup of fluid between the lung and chest wall (known as the pleural effusion).

Other diagnostic tests include a magnetic resonance scan or MRI test, which makes use of magnets and radio waves to create a series detailed images of the inside of the body. A surgical biopsy is a different method for doctors to identify mesothelioma. A surgical biopsy is when doctors take a small amount of tissue from the peritoneum or pleura to conduct further tests. A pathologist will then look at the tissue using a magnifying glass to determine if it is a cancerous cell.

The type of mesothelial cell involved, the malignant or benign nature of those cells as well as the location and stage of the cancer are used to categorize the disease. Some types of mesothelioma are more likely to spread or metastasize 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 can also perform tests in the lab on tumors in order to determine specific genes, proteins or other elements that can aid in describing cancer characteristics and plan treatment. These results are called staging.

Treatment

A mesothelioma diagnosis is terrifying. However, it's important to remember that the disease is treatable, particularly in its initial stages. Many patients with mesothelioma survive for years with the disease, without spreading to other organs of their body.

Exposure to asbestos can cause mesothelioma in many ways. Asbestos fibers, which are too small to detect or feel with the naked eye, can become airborne and irritate the lining of the lungs (pleura). In time irritation can lead to formation of scar tissue which causes changes in the cell structure which eventually lead to tumors.

The pleura is a protective covering that surrounds the abdomen, heart, and lungs. Mesothelium consists of cells that react when exposed to asbestos. They cause inflammation of the tissue and cause it to scar. These changes can cause mesothelioma cancers.

A shortness of breath, chest discomfort or fluid buildup on the lungs are all indications of the pleural msothelioma. In rare cases, cancer can spread into the tissues that surround the reproductive organs and the heart.

A doctor will order biopsy if imaging scans reveal a possible lung tumor or stomach. During the procedure, doctors take a small sample of the tumor or fluid for lab tests. The results can confirm a mesothelioma diagnosis and determine the best treatment plan.

There are many types of treatment for mesothelioma, including chemotherapy and surgery. Most doctors rely on the combination of these methods. Participating in clinical trials of mesothelioma treatments that are new could be beneficial to patients. To learn more, patients should speak to mesothelioma specialists who have expertise in treating the condition.
