Mesothelioma and Asbestos
Asbestos is a mineral that naturally occurs in the form of thin, long fibers. People who are regularly exposed to Asbestos Legal risk developing lung diseases such as mesothelioma.
It could take a long time before symptoms begin to manifest after asbestos exposure. Different asbestos types may cause different symptoms.
Pleural Mesothelioma
Pleural mesothelioma is a cancer that occurs in the outer lung lining (pleura). It is the most frequent mesothelioma type, accounting for up 70 to 79% of diagnosed cases. The condition can cause chest pain, breath shortness and a feeling heavyness.
Exposure to asbestos, a group of minerals made of microscopic fibers, usually causes this type of cancer. When inhaled, these fibers cling to the lung and cause irritation which causes scarring and DNA mutations. Pleura surrounds both the chest cavity and the lungs, which means that irritations can also affect the heart. Mesothelioma symptoms are usually not apparent until 30 to 50 years after exposure.
Shortness of breath and chest pain are the most frequent symptoms. Some patients also experience difficulty breathing or chest tightness. Patients with this cancer have a history that includes asbestos exposure at work. Construction, manufacturing and shipbuilding are among the most frequent jobs that put people at high danger of developing pleural melanoma. People who have served in the military are at an especially high risk due to the widespread use of asbestos in Navy vessels and bunkers used by the army.
The most common staging system for pleural mysothelioma has been the TNM (tumor, lymph nodes and metastases) staging system. The stage a patient has upon diagnosis will aid their doctor in determining the best treatment plan for them. For instance, patients who have mesothelioma that is pleural in stage three or four have a less favorable prognosis than those in a lower stage. Stage four mesothelioma is often spread to the diaphragm, liver or even the heart of a patient. This makes it more difficult to treat and raises the chance of complications for patients.
Peritoneal Mesothelioma
As opposed to pleural mesothelioma that is a lung-lining cancer, peritoneal mesothelioma is found in the peritoneum -- a membrane that lines the abdominal cavity and organs like the intestines and liver. Like pleural mesothelioma, exposure to asbestos 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 years to show. Patients typically suffer from abdominal pain and may also have a lump in their abdomen. This mesothelioma type can also cause nausea, weight loss, and fever. Many of these symptoms could be mistaken for gastrointestinal problems which can lead to a mistaken diagnosis.
Typically, doctors can identify mesothelioma by conducting a thorough health history and physical examination. Imaging tests like X-rays or CT scans are a way to identify mesothelioma. These tests can reveal tumors as well as other signs of cancer that are not visible on X-rays.
The results of these tests allow 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 asbestos exposure. People who have been exposed to asbestos in professions, such as plumbing or electrical work, or in construction, manufacturing and manufacturing, are more likely to develop the disease. However, even if people aren't employed in these areas they could be exposed to asbestos law through family members or through other sources. This is why anyone who suspects they may be at risk should talk to an experienced doctor. A mesothelioma specialist can assist those who have a previous history of asbestos to find out more about their risk.
Risk Factors
Asbestos exposure is a major risk factor for mesothelioma accounting for up to 80 percent of cases. Exposure to asbestos can happen through military service, work, or living with people who have worked with asbestos. Asbestos particles are inhaled by people who are exposed to asbestos. These irritate the linings and trigger cancerous cells to develop in the mesothelium. After asbestos exposure, mesothelioma may occur between 15 and 60 year.
Other risk factors include smoking, genetics and age. People in their 40s and 50s are more likely get mesothelioma than people younger or older. It takes mesothelioma between 20 and 60 years before it manifests cancer symptoms after the first exposure. It is important to keep in mind that mesothelioma may develop in those who have been exposed to asbestos, but without having directly worked with it. This is called indirect or secondary exposure to asbestos. It could be as hazardous as direct exposure.
Smoking can increase the likelihood of developing mesothelioma since it causes mesothelium damage and makes it more vulnerable to asbestos. Additionally, mesothelioma can be caused by certain illnesses, such as asbestosis and pneumonia. Men are more likely to develop mesothelioma compared to women. This is because men are more likely to work with asbestos and have a longer period of exposure than women. Men are also more likely to have lived with someone who has worked with asbestos, and to carry asbestos fibers on their clothing. Women tend to have less exposure to asbestos and don't typically carry asbestos litigation on their clothing.
Diagnosis
Mesothelioma is a difficult cancer to identify because the symptoms can be similar to other conditions. Because of this, victims are sometimes mistakenly diagnosed.
The first step in identifying mesothelioma is for NYU Langone doctors to perform an examination of the body and take note of the medical history of the patient, including asbestos exposure. Doctors will also recommend an CT scan or chest X-ray in order to look for abnormalities, lumps and evidence of asbestos exposure. These include plaques in the pleura, thickened pleura and calcium deposits.
Other diagnostic tests include a magnetic resonance image, or MRI test, which uses radio waves and magnets to create a series of detailed images of inside the body. A surgical biopsy is yet another way for doctors to diagnose mesothelioma. In a surgical biopsy doctors will remove a small piece of tissue from the pleura or the peritoneum, to be examined further. A pathologist then examines the tissue with a magnifying glass to determine if it contains cancerous cell.
The type of mesothelial cell involved and the benign or malignant nature of the cells and the location and stage of the cancer are used to categorize the disease. Certain types of mesothelioma are at an increased risk of spreading or metastasizing and it's crucial to determine the type of mesothelioma so doctors can treat it 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 factors that can aid in describing cancer characteristics and determine the best treatment. These results are called staging.
Treatment
A mesothelioma diagnosis is an incredibly frightening prospect. It is important to keep in mind, however, that cancer can be treated particularly in its initial stages. A lot of people suffering from mesothelioma be afflicted for a long time, without expanding.
Asbestos exposure can trigger mesothelioma via a variety of mechanisms. Asbestos fibers, which are too small to be felt or seen through the naked eye are able to become airborne, irritating the lung's lining (pleura). Over 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 covers the abdomen, heart, and lungs. Mesothelium is composed of cells that respond when exposed to asbestos. They cause inflammation of the tissue and cause it to scar. These changes can cause mesothelioma cancers.
The signs of pleural mesothelioma can include breathlessness and chest pain as well as the accumulation of fluid in the lung (pleural effusion). In rare instances the cancer may grow to the tissues surrounding the heart and reproductive organs.
A doctor will request biopsy if imaging scans reveal a possible mass in the lungs or stomach. In the course of the procedure, doctors remove some of the fluid or tumor for lab tests. The results will confirm a mesothelioma diagnosis, and indicate the best treatment option.
There are a variety of treatment for mesothelioma including chemotherapy and surgery. The majority of doctors use an amalgamation of these techniques. Participating in clinical trials for mesothelioma treatments may be beneficial to patients. Patients can learn more by speaking with a mesothelioma doctor who has treated mesothelioma.
