Guide To Mesothelioma And Asbestos: The Intermediate Guide To Mesothelioma And Asbestos
Mesothelioma and Asbestos
Asbestos is a naturally occurring mineral that is found in thin, long fibres. Workers who are regularly exposed to asbestos may develop lung diseases such as mesothelioma.
It could take a long time for symptoms to show up after exposure to asbestos. Different asbestos types can cause different symptoms.
Pleural Mesothelioma
Pleural mesothelioma is a cancer of the lung's outer lining, also known as the pleura. It is the most frequent form of mesothelioma and is responsible for 70 to 79% all diagnosed cases. Patients with this disease experience pain in the chest and breath shortness, and they may feel the sensation of weight in the chest.
Exposure to asbestos, a group of minerals made of microscopic fibers, usually causes this kind of cancer. Once inhaled, the fibers are absorbed into the lungs and cause irritation that causes scarring and DNA mutations. Pleura covers both the chest cavity and the lungs, and so irritations can also affect the heart. Mesothelioma usually doesn't show symptoms until 30 to 50 year after exposure.
The most frequent symptoms of pleural melanoma are chest pain and shortness of breath. Some patients may also suffer from chest tightness or coughing. They may also experience difficulty breathing. People with this cancer often have previous exposure to asbestos in the workplace. Construction, manufacturing and shipbuilding are among the most prevalent jobs that put people at high chance of developing pleural mesothelioma. People who served in the military are at greater risk due to the frequent use of asbestos case in Navy vessels and bunkers for the Army.
The most common staging system for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage a patient is in at diagnosis will assist their doctor in determining the most effective treatment plan for them. For example, patients with mesothelioma that is pleural in stage three or four have a poorer prognosis than patients with lower stages. Stage four mesothelioma can spread to the liver, heart, or diaphragm. This makes the cancer more difficult to treat and increase the chances of complications for the patient.
Peritoneal Mesothelioma
In contrast to pleural mesothelioma which is a lung-lining cancer, peritoneal mesothelioma is found in the peritoneum, it is a membrane that lines the abdominal cavity and organs like the intestines and liver. Similar to pleural mesothelioma, exposure to asbestos is the cause of peritoneal msothelioma. Only 300-500 cases are diagnosed each year this is less than pleural asbestosis.
As with pleural asbestosis, symptoms can take several years to show. Patients generally have abdominal pain, and could also experience a mass in their abdomen. This mesothelioma type can cause nausea, weight loss and fever. A lot of these symptoms can be misinterpreted as digestive issues and can lead to a false diagnosis.
Typically, doctors can identify mesothelioma by conducting an exhaustive health history and physical examination. Imaging tests like X-rays or CT scans are a way to identify mesothelioma. These tests can detect tumors and other cancer signs that are not visible on X-rays.
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 as well as whether the tumor has spread.
Asbestos exposure is the main risk factor. People who have worked in professions which require asbestos legal, such as plumbing electrical work, manufacturing or construction, are at greater risk of developing the disease. Even if an individual isn't employed in any of these areas, he or she can still be exposed through family members and other sources. Anyone who suspects that they are at risk should consult an expert. If they have any history of exposure to asbestos or mesothelioma, a specialist can assist them in finding out more about their risk.
Risk Factors
Asbestos exposure is the primary risk factor for mesothelioma which accounts for as much as 80 percent of cases. Exposure to asbestos can happen due to military service, work, or living with those who worked with asbestos. When exposed to asbestos, small particles can be inhaled into the lungs and abdomen. The particles cause irritation to the linings of the abdomen, which causes 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 the advancing age. People in their 40s and 50s are more likely to develop mesothelioma than those who are younger or older. It is because mesothelioma generally takes 20 to 60 years from the initial exposure to asbestos before cancer symptoms appear. It is important to note, too, that mesothelioma may be present in those who have been exposed to asbestos, but without having been directly exposed to it. This is known as indirect or secondary exposure to asbestos litigation. It can be just as dangerous as direct exposure.
Smoking increases a person's chances of developing mesothelioma since it causes mesothelium damage and makes it more prone to asbestos legal. Additionally, mesothelioma can be worsened by certain diseases like pneumonia and asbestosis. Men are more likely to develop mesothelioma than women. This is because men are more likely to work with asbestos law and experience a an extended period of exposure than women. Men are also more likely to have lived with someone who had worked with asbestos, and to have asbestos fibers on their clothing. Women are less likely to be in contact with asbestos, and don't typically bring asbestos home on their clothes.
Diagnosis
It is difficult to recognize mesothelioma since its symptoms are often similar to other conditions. Because of this, victims are sometimes mistakenly diagnosed.
The first step to diagnose mesothelioma is for NYU Langone doctors to perform an examination of the body and take notes on the medical history of a patient including asbestos exposure. Doctors can also order a chest X-ray or CT scan to look for lumps and other abnormalities and also to look for evidence of past asbestos exposure such as plaques on the pleura (thickened pleura with calcium deposits) and the accumulation of fluid between the lung and chest wall (known as pleural effusion).
Other diagnostic tests include a magnetic resonance image, or MRI test, that uses magnets and radio waves to create a series of detailed images of the inside of the body. Another method doctors use to diagnose mesothelioma is through the procedure of a surgical biopsy. During a surgery biopsy, doctors remove a tiny piece of tissue from pleura or the peritoneum, to be further examined. A pathologist is then able to look at the tissue under microscopes to determine if it has cancerous cells.
Mesothelioma is classified based on the mesothelial type involved, whether those cells are benign or malignant and the location of the tumor, its type, and the stage of the cancer. Certain types of mesothelioma are more likely to develop metastasis or spread, so it is important to get a definite diagnosis so doctors can treat the disease before it becomes out of control.
Doctors may also conduct laboratory tests on tumors to determine specific proteins, genes and other factors which can help them identify the characteristics of cancer and plan treatment. These results are called staging.
Treatment
A diagnosis of mesothelioma may be frightening. However, it's important to remember that the disease is treatable, particularly in its early stages. Many patients with mesothelioma survive for a long time with the disease, without spreading to other parts of their body.
Exposure to asbestos can cause mesothelioma through a variety of ways. Asbestos fibers, too small to detect or feel through the naked eye, can become airborne and irritate the lining of the lungs (pleura). As time passes irritation can lead to formation of scar tissue which leads to changes in the structure of cells that can eventually grow into tumors.
The Pleura is a covering that covers the lungs, heart and abdomen. Mesothelium is composed of cells that react when exposed to asbestos. They cause inflammation to the tissue and cause it to become scarred. As time passes, these changes cause the development of malignant mesothelioma cancers.
A shortness of breath, chest pain or fluid accumulation on the lungs are all indications of the pleural mesothelioma. In rare cases cancer can spread to the tissues surrounding the reproductive organs as well as the heart.
A doctor will order biopsy if imaging scans show the possibility of a lung tumor or stomach. In the course of the procedure, doctors remove some of the fluid or tumor to allow for lab tests. The results can confirm the diagnosis of mesothelioma and help determine the most effective treatment plan.
There are many types of mesothelioma treatment, including chemotherapy, surgery and immunotherapy. Most doctors use the combination of these treatments. Patients could also benefit from taking part in a clinical trial of new mesothelioma treatments. Patients can learn more by consulting a mesothelioma expert who has treated mesothelioma.
