Mesothelioma and Asbestos
Asbestos is a natural mineral that comes in thin, long fibres. Workers who are exposed to asbestos on a regular basis are at risk of developing mesothelioma or other lung diseases.
It could take a long time for symptoms to show up after asbestos exposure. Different asbestos types can cause different symptoms.
Pleural Mesothelioma
Pleural mesothelioma is a type of cancer that affects the lung’s outer liner (pleura). It is the most prevalent mesothelioma type and accounts for 70% to 79% of all diagnosed cases. The condition can cause chest pain, breath shortness, and a feeling of heavyness.
Exposure to brighton asbestos lawyer, a group of minerals made of microscopic fibers, usually causes this type of cancer. These fibers, when inhaled, cause irritation and DNA mutations. The pleura covers the lungs and chest cavity and therefore, these irritations could affect both the lungs and a person’s heart. Mesothelioma usually doesn’t show symptoms until 30 to 50 years after exposure.
Shortness of breath and chest pain are the most frequent symptoms. Patients may also feel tightness in their chest and coughing, or breathing difficulties. People with this cancer often have an history of exposure to asbestos in the workplace. The most common jobs that expose people to the risk of pleural mesothelioma include manufacturing, construction, and shipbuilding. Individuals who have been in the military are at risk due to the widespread asbestos usage in Navy ships and bunkers used by the army.
The most common staging system 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 what treatment plan they will receive. For instance, patients suffering from mesothelioma that is pleural in stage three or four have a less favorable prognosis than those in lower stages. Stage four mesothelioma often spreads to the diaphragm, liver and/or a person’s heart. This makes it more difficult to treat and increase the risk of complications for patients.
Peritoneal Mesothelioma
Unlike pleural mesothelioma, which develops in the lung lining, peritoneal mesothelioma is found in the peritoneum — an elongated membrane that covers the abdominal cavity as well as organs such as the liver and intestines. Similar to pleural mesothelioma and peritoneal mesothelioma can be caused by asbestos exposure. It is estimated that only 300-500 cases are diagnosed each year which is lower than pleural asbestosis.
Like pleural mesothelioma, symptoms can take years to show. Patients generally have abdominal pain, and may also have a lump in their abdomen. This kind of mesothelioma can cause nausea, weight loss, and fever. A lot of these symptoms are similar to those experienced by gastrointestinal issues, which can result in confusion in diagnosis.
The doctors can detect mesothelioma through examining the patient’s medical history and performing a physical examination. Imaging tests such as X-rays or CT scans are a way to detect mesothelioma. These tests can show tumors, as well as other indications of cancer that aren’t visible on an X-ray.
These test results enable doctors to diagnose mesothelioma and establish the stage. They can also suggest treatment options. The stage is determined by the type of cell and whether the tumor has spread.
Asbestos exposure is the most important risk factor. People who have worked in asbestos-related occupations, like electrical or plumbing work or in manufacturing and construction, are more likely to contract the disease. However, even if individuals do not work in these areas they could be exposed to asbestos through family members or other sources. Anyone who believes they are at risk should consult an expert. If they have an history of exposure to asbestos, a mesothelioma specialist can help them find out more about the risk.
Risk Factors
Asbestos exposure is a major mesothelioma risk factor, which accounts for as much as 80 percent of all cases. Exposure to asbestos may occur as a result of military service, work or living with someone who used to work with asbestos. Asbestos particles can be breathed in by people who are exposed to asbestos. They can cause irritation to the linings of the abdomen and trigger cancerous cells to grow in the mesothelium. Mesothelioma can take between 15 and 60 years to develop following exposure to asbestos.
Other risk factors include smoking, genetics and aging. People in their 40s and 50s are more at risk of developing mesothelioma compared to people who are younger or more. It takes mesothelioma 20-60 years to show signs of cancer after the first exposure. It is important to note that mesothelioma can occur in people who have been exposed to garden city Asbestos law firm, but without having directly worked with it. This is called secondary or indirect exposure to asbestos, and it can be just as dangerous as direct exposure.
Smoking increases the chance of mesothelioma as it damages the mesothelium. It also makes it more susceptible. Mesothelioma can also be aggravated by certain illnesses such as asbestosis and pneumonia. Men are more likely to develop mesothelioma than women. Men are more likely than women to have been exposed to asbestos for a longer period of time and work with asbestos for longer periods of time. Men are also more likely to live with someone who worked with asbestos and carry asbestos fibers that have escaped home on their clothes. Women are less likely to come into contact with asbestos and do not typically carry asbestos around on their clothes.
Diagnosis
It is difficult to diagnose mesothelioma due to its symptoms being frequently similar to other illnesses. Due to this, patients are sometimes wrongly diagnosed.
The first step to diagnose mesothelioma is for NYU Langone doctors to perform an examination and write notes on the medical history of a patient including asbestos exposure. Doctors may also request a CT scan or chest X-ray to look for lumps, abnormalities 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 and magnetic resonance imaging, also known as MRI test, which makes use of radio waves and magnets to create detailed images of the inside of the body. Another method doctors use to diagnose mesothelioma is by performing a surgical biopsy. In a surgical biopsy doctors take a small amount of tissue from the peritoneum or pleura for further testing. A pathologist then examines the tissue using an magnifying glass to determine if it contains cancerous cell.
Mesothelioma is classified according to the mesothelial type involved, whether these cells are malignant or benign, and the location, type, and stage of the tumor. Certain types of mesothelioma are more likely to spread or metastasize and spread, therefore it is essential to have a clear diagnosis so doctors can treat the disease before it goes out of control.
Doctors may also conduct tests in the lab on tumors to determine specific proteins, genes and other factors that help them understand the cancer’s characteristics and plan treatment. These results are referred to as staging.
Treatment
A mesothelioma diagnosis is terrifying. But, it is crucial to remember that the disease can be treated, particularly in its earlier stages. Many people with mesothelioma live for many years with the disease without it spreading to other organs of their body.
Exposure to asbestos can trigger mesothelioma via a variety of mechanisms. Asbestos fibers, too small to see or feel by the naked eye can be airborne and cause irritation to the lining of the lungs (pleura). In time irritation leads to formation of scar tissue, which can cause changes in the cell structure that can eventually grow into tumors.
The pleura is a protective covering that protects the abdomen, heart, and lungs. Mesothelium consists of cells that react to exposure to asbestos, causing it to inflame and create scar tissue. These changes can eventually cause mesothelioma cancers.
Symptoms of pleural mesothelioma include breathing problems, chest pain or the accumulation of fluid on the lungs (pleural effusion). In rare cases cancer may spread to the tissues around the reproductive organs and the heart.
If scans of imaging reveal an underlying mass in the lungs or stomach the doctor will request a biopsies. During the procedure, doctors remove tiny amounts of fluid or tumor for laboratory testing. The results will confirm a mesothelioma diagnosis, and indicate the most effective treatment plan.
There are a variety of mesothelioma treatment, including chemotherapy, surgery and immunotherapy. Most doctors rely on an amalgamation of these techniques. Patients could also benefit from enrolling in a clinical trial of new mesothelioma treatments. Patients can learn more by speaking with a mesothelioma doctor who has treated mesothelioma.
