Mesothelioma and Asbestos

Asbestos, a natural mineral, occurs naturally in the form of long, thin fibers. Workers who are regularly exposed to Asbestos Legal risk developing lung diseases, such as mesothelioma.

It may take decades for symptoms to show up after exposure to asbestos. Different asbestos types can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma occurs in the lung's outer lining, also known as pleura. It is the most prevalent mesothelioma that accounts for up 70% to 79% of diagnosed cases. Patients suffering from this condition experience pain in the chest and breathlessness and may also feel a sensation of heaviness in the chest.

Exposure to asbestos attorney, a family of minerals made of microscopic fibers causes this kind of cancer. When inhaled, these fibers, cause irritation and DNA mutations. Pleura is the lining of both the chest cavity as well as the lungs, and so irritations can also affect the heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

The most frequent symptoms of pleural mesothelioma are chest discomfort and shortness of breath. Some patients also experience difficulty breathing, or chest tightness. People who suffer from this cancer usually have an history of exposure to asbestos in the workplace. Construction, manufacturing and shipbuilding are the most prevalent occupations which put people at risk risk of developing pleural mesothelioma. People who served in the military are at greater risk due to the extensive use asbestos in Navy vessels and bunkers in the Army.

The TNM (tumors, lymph nodes, and metastases staging system) is the most common staging system used for the pleural adenocarcinoma. The stage the patient is in at the time of diagnosis can help determine the treatment plan they should follow. For instance, patients suffering from mesothelioma pleural stage three or four have a less favorable prognosis than those with a lower stage. Stage four mesothelioma may develop into the liver, heart or diaphragm. This makes it more difficult to treat and increases the risk of complications for the patient.

Peritoneal Mesothelioma

In contrast to pleural mesothelioma which develops in the lung lining, peritoneal mesothelioma develops in the peritoneum -- a membrane that lines the abdominal cavity and organs like the intestines and the liver. Similar to pleural mesothelioma, asbestos exposure is the cause of peritoneal msothelioma. The disease is much less prevalent than pleural mesothelioma, and around 300-500 cases being diagnosed each year.

Like pleural mesothelioma, the symptoms can take years to show. Patients usually experience abdominal pain, and may have a mass in their abdomen. The symptoms of this kind of mesothelioma may also include nausea as well as weight loss and fever. Many of these symptoms can be mistaken for gastrointestinal problems which can lead to a false diagnosis.

Doctors can identify mesothelioma by reviewing the medical history of the patient and performing a physical exam. They can also utilize imaging tests such as X-rays, CT scans and PET/CT scans to identify mesothelioma. These tests can detect tumors and other signs of cancer that aren't visible on X-rays.

These test results enable doctors to identify mesothelioma, and determine the stage. They can also suggest treatment options. The stage is determined by the type of cell and whether the cancer has spread.

The most important risk factor for mesothelioma is asbestos exposure. People who have worked in professions that require asbestos, such as plumbing manufacturing, electrical work or construction, are at increased risk of developing the disease. Even if someone does not work in one of these areas, he or she can still be exposed through family members and other sources. Anyone who believes they're at risk should speak with an expert. If they have a history of asbestos exposure, a mesothelioma specialist can help them find out more about the risk.

Risk Factors

Asbestos exposure is the main risk factor for mesothelioma, accounting for up to 80 percent of cases. Exposure to asbestos can happen through work, military service or through living with a person who is exposed to asbestos or has previously done the same. asbestos settlement particles are inhaled by those who are exposed to it. The particles cause irritation to the linings of the lungs, causing cancerous cells to grow in the mesothelium. After asbestos exposure mesothelioma is likely to occur between 15 and 60 year.

Other risk factors include smoking, genetics and age. People in their 40s and 50s are at a higher chance of developing mesothelioma to people who are younger or more. It takes mesothelioma 20-60 years to manifest cancer symptoms after the first exposure. It is important to note, too, that mesothelioma can develop in people who have been exposed to asbestos, but without having been directly exposed to it. This is referred to as indirect or secondary exposure to asbestos, and it is just as harmful as direct exposure.

Smoking can increase the likelihood of developing mesothelioma due to the fact that it damages the mesothelium, which makes it more vulnerable to asbestos. In addition, mesothelioma may be exacerbated by certain illnesses like asbestosis and pneumonia. It is also important to remember that mesothelioma is more prevalent in men than women. This is due to men being more likely to work with asbestos 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 asbestos fibers that have escaped home on their clothing. Women are less likely to come into exposure to asbestos and rarely carry asbestos around on their clothing.

Diagnosis

Mesothelioma is a difficult cancer to recognize because the symptoms can be similar to other diseases. This can lead to victims being misdiagnosed.

NYU Langone doctors will perform physical examinations and document the patient's medical history including asbestos exposure. Doctors will also recommend an CT scan or chest X-ray to look for lumps, abnormalities, and evidence of exposure to asbestos. These include pleural plaques, thickened pleura and calcium deposits.

Other diagnostic tests include an echocardiogram which examines the blood vessels and the heart as well as a magnetic resonance imaging, or MRI test, which makes use of magnets and radio waves to create detailed images of the inside of the body. Another method doctors use to diagnose mesothelioma is by performing the procedure of a surgical biopsy. During a surgical biopsy, doctors remove a small amount of tissue from the peritoneum or pleura for further analysis. A pathologist can examine the tissue with microscopes to determine whether it contains cancerous cells.

The mesothelial type involved, the malignant or benign nature of those cells and the location, type and stage of the tumour, are used to categorize the disease. Certain mesothelioma types have an increased risk of spreading or metastasizing, so it's important to establish a clear diagnosis to ensure that the doctors can treat it before it becomes out of control.

Doctors may also conduct tests in the lab on tumors to identify specific proteins, genes or other elements that can aid in describing cancer characteristics and determine the best treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be terrifying. It is important to keep in mind that cancer can be treated, particularly in its early stages. Many mesothelioma patients live for many years with the disease without it spreading to other areas of their body.

Asbestos exposure can trigger mesothelioma via many mechanisms. Asbestos particles, which are too small to detect or feel with 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 covers the lungs and the heart and also the abdomen. Mesothelium consists of cells that respond when exposed to asbestos lawsuit. They cause inflammation of the tissue and cause it to become scarred. These changes can eventually lead to malignant mesothelioma tumours.

The signs of pleural mesothelioma can include breathing problems, chest pain or an accumulation of fluid on the lungs (pleural effusion). In rare instances, the cancer can grow to the tissues surrounding the heart and reproductive organs.

If imaging scans reveal a possible mass in the lungs or stomach the doctor will request a biopsies. The procedure involves the removal of a small amount of fluid or tumor for laboratory testing. The results will confirm the diagnosis of mesothelioma and help determine the best treatment option.

There are many types of mesothelioma treatment, which include chemotherapy, surgery, and immunotherapy. The majority of doctors employ combinations of these treatments. Participating in clinical trials for new mesothelioma treatment may also be beneficial to patients. To learn more about the trials, patients should speak to a mesothelioma specialist who has experience treating the condition.
