Mesothelioma and Other Asbestos Related Cancers

People with an exposure history to asbestos are at risk for different types of cancers that include mesothelioma. These cancers have a latency time of many years, meaning that symptoms may not appear until decades after exposure.

The risk of pleural or peritoneal msothelioma diminishes after first exposure. The evidence is based on six occupational cohort studies and two residential cohorts with long-term following.

What is Mesothelioma?

Mesothelioma is a cancer of the internal organs' lining which include the lungs (pleural mesothelioma) and abdomen (peritoneal mesothelioma) or heart (pericardial mesothelioma). It is a rare and aggressive disease that usually begins in the lining in the chest cavity. However, it could also affect the lining of the stomach, as well as other parts of your body. Asbestos exposure is the most common reason for mesothelioma, and the cancer usually doesn't show up until decades after the initial exposure.

People who are exposed to asbestos in the workplace are at an increased risk of developing cancer than other. Asbestos fibers can be inhaled or swallowed and bind to the organ lining. They can cause irritation to the lining which causes abnormal cells to grow and forming tumors. The symptoms usually don't manifest until a person has advanced mesothelioma.

Most asbestos case exposure occurs in industrial settings, where workers handle the substance or work around it. Asbestos is used in a variety of trades, such as construction, shipbuilding and auto repair. Veterans who served in the military are particularly at risk for mesothelioma, as asbestos was used extensively on ships and bases.

Patients with a history of asbestos exposure need to have regular checkups and be aware of any unusual symptoms. If a doctor suspects mesothelioma they may request imaging scans, such as CT scans or MRI scans to look for tumors and determine if they've gotten larger. They may also ask about the patient's history of asbestos exposure and perform an examination. Certain cases of mesothelioma may be caused by genetic changes. So, certain patients may benefit from genetic tests.

Risk Factors

The main mesothelioma risk factor is exposure to asbestos. Asbestos is a mineral comprised of fibers, is resistant to heat and strong. Asbestos is utilized in a variety of manufacturing and construction materials, such as insulation, brakes and shingles. Asbestos dust is inhaled and swallowed when disturbed. This can cause irritation of mesothelium, which can eventually lead to mesothelioma.

People who have an history of occupational asbestos exposure are at most risk of mesothelioma. This includes those who worked in industries like shipbuilding, mining, construction and automotive repair. Veterans of the military are also at risk, since many branches of service used asbestos-based material.

Other factors that increase the risk of mesothelioma include an asbestos-related family history exposure as well as prior treatment for chest cancer with radiation. Additionally, the type of mesothelioma that is diagnosed has a significant impact on the risk. Pleural mesothelioma, the most common form and typically affects the lungs. Other mesothelioma types include peritoneal, pericardial and testicular.

In general mesothelioma is a cancer that increases with the third or fourth power of latency - which is the length of time it takes for someone to be diagnosed. However, the incidence of pleural mesothelioma shows a slight flattening approximately 40 years of exposure. Peritoneal and pericardial mesothelioma both exhibit this trend too. Para-occupational asbestos attorney exposure, such as living near an asbestos plant or eating household products that are contaminated can also increase the risk of mesothelioma. A study of six cities revealed that those with this type of exposure had a greater mesothelioma danger than those who only had occupational exposure.

Symptoms

The linings of internal organs are affected by malignant mesothelioma. Most often, it is found in the linings of the lungs and abdomen. Mesothelioma can also occur in the lining around the testicles or heart. It is a rare type of cancer. The majority patients diagnosed with mesothelioma were employed in jobs where they were exposed to asbestos. It could take years for mesothelioma-related symptoms to develop and the condition is not curable.

Asbestos is made up of an assortment of minerals that possess microscopic fibers and are impervious to heat, chemicals and fire. It was once extensively used in shipbuilding, construction manufacturing, and other industries. Exposure to asbestos can lead to mesothelioma because the fibers get stuck in the tissues that line and protect organs, causing irritation and damaging cells. This can result in tumors growing and eventually becoming cancerous.

The most prevalent form of mesothelioma occurs in the wall (pleura) of the lungs. It can also start in the abdomen's lining (peritoneum) or in the membrane that surrounds the heart or testicles. Mesothelioma can also expand to lymph nodes, causing swelling of the lymph nodes.

Most people diagnosed mesothelioma suffer from a history of exposure to asbestos and also suffer from other diseases, such as chronic pulmonary disease. Mesothelioma symptoms are similar to the symptoms of other diseases, and you should consult a doctor when any recurring or alarming symptoms persist. Doctors can inquire about asbestos exposure in the past and conduct a physical exam. They can also order scans of your body or blood tests of your abdomen and chest. They can detect any thickening of the lung's lining, or the fluid that is leaking out of the space between your lungs and the chest wall.

Diagnosis

When asbestos fibers become stuck to the body, they can cause damage and may eventually develop into cancerous tumors. Different kinds of asbestos settlement-related cancers form in various organs or tissues, and each type can be identified using different tests. Mesothelioma develops in the lining of the chest cavity and the lungs (pleura), the stomach membranes (peritoneum) or around the heart and reproductive organs.

The first step to diagnose mesothelioma is to speak with his or her doctor about their experience with asbestos exposure and what symptoms they've been experiencing. Doctors will also conduct physical examinations and tests to determine the health of the lung.

X-rays or CT scans can aid doctors in identifying the affected area more clearly. In certain cases doctors will perform an pleural effusion test in order to determine if mesothelioma or another disease is causing fluid accumulation in the lung. The pleural effusion can be a sign of mesothelioma of the pleura, peritoneal mes or a rarer type of mesothelioma called biphasic or mixed mesothelioma.

The mesothelioma symptoms are frequently misdiagnosed, as they resemble those of other illnesses. The most frequent symptoms are chest pain and breathing difficulties. Pleural mesothelioma can also cause a cough, chest tightness and fatigue. Peritoneal mesothelioma may cause abdominal discomfort, swelling and distension. Testicular mesothelioma may manifest as a painful, itchy lump on the testicles.

Researchers are studying proteins in blood to create methods to detect mesothelioma in the early stages. They are also researching a number of other tests and procedures that may improve the accuracy of diagnosis, such as mesothelioma scans and MRIs. They are also studying genetic mutations and how to determine if a person has a mesothelioma-related risk by looking at their family background.

Treatment

Asbestos exposure is the main risk factor for mesothelioma. People who worked with asbestos in the past, particularly for prolonged periods of time, or in high-risk jobs like construction, shipbuilding, electrical work, military and auto repair are at greater risk.

Exposure to asbestos may cause mesothelioma when the fibers get stuck in the tissue that lines vital organs and protects them. The mesothelium is irritated by the asbestos fibers and cause DNA damage, which leads to cancerous cells. Mesothelioma symptoms typically don't manifest until decades after exposure.

Symptoms differ depending on the type of mesothelioma as well as the place it develops within the body. Most mesothelioma cases involve lung lining (pleural mesothelioma) however it may also be found in the lining of the stomach (peritoneal mesothelioma) or the heart (pericardial mesothelioma) or testicles (testicular mesothelioma).

Mesothelioma staging helps doctors determine treatment options. The cancer is classified as stage I through stage IV with stages I and II being the most early and most treatable. Stage III and stage IV are the last stages of cancer, and are more difficult to treat. However there are many options for treatment.

Pleural mesothelioma is by far the most frequent form of the disease and affects the lining of the lungs and chest wall, as well as the abdomen. In the majority of cases of pleural mesothelioma, asbestos exposure happened in the workplace. It was most likely due to breathing in airborne asbestos particles or ingestion of the cancerous substance through the food chain.

Other risk factors are a family history, genetic mutations, and prior treatment with radiation for a different ailment. If you have been exposed to asbestos and are suffering from mesothelioma symptoms, it is essential to consult a doctor. You could also benefit from genetic counseling. In some cases mesothelioma experts can help you file a lawsuit against companies that have knowingly used asbestos in their everyday products.
