Mesothelioma and Asbestos

Asbestos, a mineral that naturally forms in the form of long, thin fibers. Workers who are exposed asbestos regularly risk developing mesothelioma and other lung diseases.

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

Pleural Mesothelioma

Pleural mesothelioma is a cancer that develops in the outer lung the lining (pleura). It is the most common mesothelioma type and is responsible 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 group of minerals comprised of microscopic fibers, usually causes this type of cancer. When inhaled, these fibers can cause irritation and DNA mutations. Pleura covers both the chest cavity and the lungs, and so irritations can also affect the heart. Mesothelioma symptoms are usually not apparent until 30 to 50 years after exposure.

The most common symptoms of pleural mesothelioma are chest pain and shortness of breath. Patients may also feel tightness in their chest, coughing or difficulty breathing. Patients with this type of cancer have a past that includes asbestos exposure at work. Construction, manufacturing and shipbuilding are the most frequent jobs that put people at high danger of developing pleural melanoma. Individuals who have been in the military could be at an especially high risk due to the frequent use of asbestos in Navy ships and army bunkers.

The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most popular staging system for the pleural adenocarcinoma. The stage a patient is in at diagnosis will assist their doctor in determining the most effective treatment plan for them. Patients with pleural mesothelioma that is in stage three or stage four will suffer a more negative outlook than those in a lower stage. Stage four mesothelioma is often spread to the liver, diaphragm and/or a person's heart. This can make it more difficult to treat and increase the chance of complications for patients.

Peritoneal Mesothelioma

Unlike pleural cancer, that develops in the lining of the lung it develops in a membrane that covers the abdominal cavity, which includes organs like the intestines and liver. Similar to pleural mesothelioma, exposure to asbestos is the reason for peritoneal msothelioma. The disease is less prevalent than pleural mesothelioma, with around 300-500 cases being diagnosed each year.

Like pleural mesothelioma, the symptoms can take years to show. Patients usually suffer from abdominal pain and could also experience a mass in their abdomen. The symptoms of this type of mesothelioma can also include nausea as well as weight loss and fever. A lot of these symptoms can be mistaken for gastrointestinal problems and can lead to a false diagnosis.

Typically, doctors can identify mesothelioma by conducting an extensive health history and physical examination. Imaging tests like X-rays or CT scans can be used to identify mesothelioma. These tests can show tumors, as well as other signs of cancer that aren't apparent on an X-ray.

The results of these tests allow doctors to diagnose mesothelioma, identify the stage and suggest treatment options. The stage is determined by the type of cell as well as whether the cancer has spread.

The most significant mesothelioma risk factor is exposure to asbestos. People who have worked in asbestos-related occupations, like plumbing or electrical work, or in construction, manufacturing and manufacturing are more likely to develop the disease. However, even if individuals do not work in these fields they may be exposed to asbestos through family members or other sources. This is why anyone who believes they could be at risk should speak to a doctor. If they have an history of exposure to asbestos, a mesothelioma specialist can assist them in finding out more about the risk.

Risk Factors

Asbestos is the primary mesothelioma-related risk factor. It accounts for up to 80percent of cases. Exposure to asbestos may occur through work, military service or by living with someone who is exposed to asbestos or was previously exposed to doing such. When exposed to asbestos, particles can be inhaled into the abdomen and lungs. The particles cause irritation to the linings, causing cancerous cells to form in the mesothelium. After asbestos exposure, mesothelioma may develop between 15 and 60 years.

Other risk factors include smoking, genetics and age. People in their 40s or 50s are at a higher risk of developing mesothelioma compared to people who are younger or more. This is because mesothelioma usually occurs between 20 and 60 years after the initial time of exposure before the first signs of cancer appear. It is important to remember that mesothelioma may develop in those who were exposed to asbestos but didn't deal with it directly. This is known as indirect or secondary exposure to asbestos and it can be just as dangerous as direct exposure.

Smoking increases the chance of mesothelioma because it damages the mesothelium. It also makes it more susceptible. Additionally, mesothelioma can be worsened by certain diseases like pneumonia and asbestosis. It is also important to remember that mesothelioma occurs more frequently in males than females. This is due to the fact that men are more likely to work with alva asbestos law firm and experience a an extended period of exposure than women. Additionally, men are more likely to live with someone who has was exposed to asbestos and bring Doylestown asbestos attorney fibers that have escaped home on their clothes. Women are less likely to come exposed to asbestos, and they don't usually bring asbestos home on their clothes.

Diagnosis

Mesothelioma is difficult to recognize because the symptoms often resemble other conditions. This can result in patients being incorrectly diagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform a physical exam and take down a patient's medical history which includes asbestos exposure. Doctors will also order a CT scan or chest X-ray to check for abnormalities, lumps and evidence of exposure to asbestos. These include plaques on the pleura, pleura that are thickened and calcium deposits.

Other diagnostic tests include a magnetic resonance scan, or MRI test, which uses magnets and radio waves in order to create a series detailed images of the insides of the body. A surgical biopsy is another way for doctors to diagnose mesothelioma. A surgical biopsy is when doctors remove a small piece of tissue from the pleura or peritoneum for further analysis. A pathologist then examines the tissue with an magnifying glass to determine if it contains cancerous cell.

The mesothelial type involved, the malignant or benign nature of the cells and the location, type and stage of the tumour, are used to categorize the disease. Certain types of mesothelioma may be more likely to spread or metastasize, so it is important to have a clear diagnosis so that doctors can treat the disease before it gets out of control.

Doctors may also conduct tests in the lab on tumors to determine particular proteins, genes and other factors which can help them identify the characteristics of the cancer and determine a treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be frightening. However, it's important to remember that the disease can be treated, particularly in its earlier stages. Many people with mesothelioma can be afflicted for many years without it spreading.

Exposure to asbestos can trigger mesothelioma through a variety of ways. Asbestos particles, which are too small to see or feel with the naked eye, can be airborne and cause irritation to the lung's lining (pleura). Over time, the irritation leads to the formation of scar tissue, which eventually lead to tumors.

The pleura is the area that surrounds the lungs and the heart and the abdomen. Mesothelium is composed of cells that respond when exposed to asbestos. They inflame the tissue and cause it to become scarred. These changes can eventually result in malignant mesothelioma tumors.

Shortness of breath, chest discomfort or fluid buildup on the lungs are all symptoms of the pleural Msothelioma. In rare cases, the cancer can grow to the tissues surrounding the heart and reproductive organs.

If imaging scans show an underlying mass in the lungs or stomach the doctor will request a biopsies. During the procedure, doctors remove tiny amounts of tumor or fluid for lab analysis. The results will confirm a mesothelioma diagnosis and indicate the most effective treatment plan.

There are a variety of treatment for mesothelioma including chemotherapy and surgery. The majority of doctors employ a combination of these treatments. Patients could also benefit from participating in a clinical study of new mesothelioma treatments. Patients can learn more by consulting a mesothelioma specialist who has treated the disease.
