Mesothelioma and Asbestos

Asbestos, a mineral that occurs naturally in the form of long, thin fibers. Workers who are exposed asbestos regularly are at risk of developing mesothelioma or other lung diseases of different types.

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

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the lung's outer lining, or pleura. It is the most frequent form of mesothelioma and accounts for 70% to 79% all diagnosed cases. This condition causes chest discomfort, shortness of breath, and a feeling of weightiness.

Exposure to asbestos, a group of minerals composed of microscopic fibers, typically causes this kind of cancer. When inhaled, these fibers, cause irritation and DNA mutations. The pleura is the area that surrounds the chest cavity and lungs This means that these irritations can affect both the lungs and a person's heart. Mesothelioma usually doesn't show symptoms until 30 to 50 year after exposure.

Chest pain and shortness breath are the most frequent symptoms. Some patients may also suffer from chest tightness and coughing, or breathing difficulties. Patients with this type of cancer typically have previous exposure to asbestos in the workplace. Manufacturing, construction, and shipbuilding are the most common jobs that put people at high danger of developing pleural melanoma. People who have served in the military may be at risk due to the widespread use of asbestos in Navy vessels and bunkers for the army.

The most popular staging method for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage that the patient is in at the time of diagnosis will help determine the treatment plan they should receive. For instance, patients suffering from mesothelioma that is pleural in stage three or four have a worse prognosis than those with lower stages. Stage four mesothelioma may spread to the liver, heart or diaphragm. This makes the cancer more difficult to treat and increase the chance of complications for patients.

Peritoneal Mesothelioma

In contrast to pleural cancer, which forms in the lung's lining, peritoneal cancer develops in a membrane that surrounds the abdominal cavity, including organs like the intestines and liver. Similar to pleural mesothelioma, exposure to asbestos is the cause of peritoneal mesothelioma. There are only 300-500 cases diagnosed each year which is lower than pleural asbestosis.

As with pleural asbestosis symptoms can take years to manifest. Patients typically have abdominal pain, and may also have a lump in their abdomen. The symptoms of this type of mesothelioma can also include nausea or weight loss, as well as fever. Many of these symptoms can be misinterpreted as digestive issues, leading to a false diagnosis.

Typically, doctors can identify mesothelioma by conducting an extensive health history and physical examination. Imaging tests such as X-rays or CT scans can be used to detect mesothelioma. These tests can identify tumors as well as other signs of cancer that are not evident on X-rays.

These test results enable doctors to diagnose mesothelioma and establish the stage. They can also suggest treatments. The staging is determined by the type of cells and whether or the cancer has spread to other areas of the body.

Asbestos exposure is the biggest risk factor. People who have worked in asbestos-containing occupations, like plumbing or electrical work, or in construction and manufacturing are more likely to contract the disease. However, even if individuals aren't employed in these fields, they can still be exposed to asbestos through relatives or other sources. For this reason, anyone who is concerned that they might be at risk should talk to a doctor. If they have an history of exposure to asbestos lawsuit, a mesothelioma specialist can assist them in learning more about their risk.

Risk Factors

Asbestos exposure is a major risk factor for mesothelioma which accounts for as much as 80 percent of cases. Exposure to asbestos may occur through work, military service or by living with a person who is exposed to asbestos or used to do so. asbestos lawyer particles can be inhaled by people who are exposed to asbestos. These particles irritate the linings, causing cancerous cells to form in the mesothelium. Mesothelioma may take between 15 and 60 years to develop after exposure to asbestos.

Other risk factors include smoking, genetics and aging. The people in their 40s or 50s are at greater chance of developing mesothelioma to those younger or older. Mesothelioma can take between 20 and 60 years before it manifests cancer symptoms after the first exposure. It is also important to know that mesothelioma can develop in those who were exposed to asbestos, but did not work with it directly. This is referred to as indirect or secondary asbestos exposure and can be just as harmful as direct asbestos exposure.

Smoking increases the chance of mesothelioma because it damages the mesothelium. It also makes it more prone to. Mesothelioma can also be caused by certain illnesses, including asbestosis and pneumonia. It is also important to remember that mesothelioma is more prevalent in males than females. Men are more likely than women to have been exposed to asbestos for longer periods of time and to work with asbestos for longer durations and to work with it. Additionally, men are more likely to live with someone who has was exposed to asbestos attorney and bring asbestos Case fibers that have escaped home on their clothing. Women tend to have less exposure to asbestos and don't typically carry asbestos around on their clothes.

Diagnosis

Mesothelioma is difficult to identify because the symptoms can be similar to other diseases. This can lead to victims being wrongly diagnosed.

NYU Langone doctors will perform physical examinations and document the patient's medical background, including asbestos exposure. Doctors can also order an X-ray of the chest or CT scan to look for lumps or other abnormalities, as well as evidence of previous asbestos exposure such as plaques on the pleura (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 imaging or MRI test, which uses radio waves and magnets in order to produce a series of precise images of the inside of the body. Another way doctors can diagnose mesothelioma is to perform the procedure of a surgical biopsy. A surgical biopsy is when doctors take a small amount of tissue from the pleura or peritoneum to conduct further tests. A pathologist can then examine the tissue under microscopes to determine whether it contains cancerous cells.

Mesothelioma is classified based on the mesothelial type involved, whether these cells are malignant or benign and also the location, type, and stage of the cancer. Certain types of mesothelioma may be more likely to grow or spread which is why it is crucial to have a clear diagnosis to ensure that doctors are able to treat the disease before it goes out of control.

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

Treatment

A diagnosis of mesothelioma can be an incredibly frightening prospect. However, it is important to remember that the disease is treatable, especially in its earlier stages. Many mesothelioma patients live for a long time without the disease spreading to other parts of their body.

Exposure to asbestos may cause 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 irritate the lung's lining (pleura). In time the irritation can lead to the formation of scar tissue and eventually tumors.

The pleura is the area that surrounds the lungs and the heart and the abdomen. Mesothelium consists of cells that react to asbestos which causes it to become inflamed and develop scar tissue. These changes can eventually result in malignant mesothelioma tumors.

The symptoms of pleural mesothelioma are breathlessness, chest pain or the accumulation of fluid in the lungs (pleural effusion). In rare cases, cancer can spread into the tissues that surround the reproductive organs and heart.

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

There are many types of mesothelioma treatments, including surgery, chemotherapy and immunotherapy. Most doctors utilize an amalgamation of these techniques. Patients may also benefit from participating in a clinical study of new mesothelioma treatment. To learn more, patients should speak to mesothelioma specialists who have had experience treating the disease.
