Mesothelioma and Other Asbestos Related Cancers

People with previous exposure to asbestos are at risk for various types of cancer such as mesothelioma. These cancers have a time-of-resistance of many years, meaning that symptoms may not appear until decades after exposure.

The risk of developing pleural or peritoneal mesothelioma declines with time from the first exposure. The evidence is built on six cohort studies of occupational exposure and two residential cohorts with long-term follow-up.

What is Mesothelioma?

Mesothelioma is a cancer of the inner organs' linings, including the lung (pleural mesothelioma) or abdomen (peritoneal mesothelioma) or the heart (pericardial mesothelioma). It's a rare and deadly disease that most often starts in the lining of the chest cavity, but it may also occur in the stomach's lining or in other parts of the body. Asbestos exposure is the most common cause of mesothelioma, and the cancer typically doesn't appear until decades after the initial exposure.

People who are exposed to asbestos at work have higher chances of developing the disease than other. Asbestos fibers can be inhaled or swallowed and cling to the lining of organs. They can cause irritation to the lining and cause abnormal cells to multiply and develop into tumors. The symptoms usually do not show until a person has developed advanced mesothelioma.

Most asbestos exposure occurs in industrial jobs, where workers handle the material or work near it. Asbestos was utilized in shipbuilding, construction, auto repair and other trades. Veterans who served in the military are at a higher risk for mesothelioma, as asbestos was used extensively on ships and bases.

People with a past history of asbestos exposure need to have regular checkups and be alert to any unusual symptoms. If a doctor suspects mesothelioma, they may order imaging tests like CT scans, MRI or PET scans to look for the tumors and see whether they have spread. They may also perform an examination and inquire about a patient's exposure to asbestos history. Some cases of mesothelioma are linked to genetic changes, which means that some patients might benefit from genetic tests.

Risk Factors

The most significant risk factor for mesothelioma is exposure to asbestos. Asbestos, a mineral composed of fibers, is resistant to heat and strong. Asbestos is utilized in a variety of manufacturing and construction products, including insulation, brakes and shingles. When asbestos is disturbed it creates dust that may be swallowed or inhaled. Over time, this can lead to irritation of the mesothelium which could eventually lead to mesothelioma.

People who have had an history of occupational asbestos exposure are at most risk of mesothelioma. This includes people who have worked in industries like construction, shipbuilding, mining, as well as automotive repair. Veterans of the military are also at risk, since many branches of military employed asbestos-based materials.

Other factors that increase the risk of mesothelioma are an asbestos-related family history exposure and prior treatment with radiation to the chest. Furthermore, the type of mesothelioma that is diagnosed has an impact on the risk. Pleural mesothelioma is by far the most prevalent form and typically affects the lungs. Other forms of mesothelioma are peritoneal, pericardial and testicular.

In general, the risk of mesothelioma increases with the third or fourth power of latency, which is how long it takes for someone to be diagnosed. However, the risk of pleural mesothelioma exhibits a slight flattening out after approximately 40 years of exposure. Peritoneal and pericardial mesothelioma both show this trend as well. Individuals who have exposure to asbestos - like living in close proximity to an asbestos plant, or consuming products from the household that are contaminated are also at higher risk of developing mesothelioma. A study of six cities showed that those with this kind of exposure were at a higher mesothelioma rate than those who had only occupational exposure.

Symptoms

Malignant mesothelioma can affect the tissue linings surrounding internal organs. It is most often seen in the lung lining (pleura) and abdomen (peritoneum). Mesothelioma can also occur in the lining around the testicles or the heart. It is a rare form of cancer and the majority of people diagnosed with mesothelioma worked in positions that exposed them to asbestos. It can take decades for symptoms of mesothelioma to develop and the disease is not curable.

Asbestos is a class of minerals with tiny, microscopic fibers that are resistant to heat, chemicals, and fire. It was widely employed in a variety of industries, such as shipbuilding, construction, manufacturing and many more. Exposure to asbestos attorney can lead to mesothelioma due to the fibers getting stuck in tissues that line organs and protect them which causes irritation and damage to cells. This can lead to tumors developing and eventually turning cancerous.

The most frequent type of mesothelioma is pleural mesothelioma, which develops in the lung's lining (pleura). It can also develop in the lining of the testicles or the heart or in the abdominal lining (peritoneum). Mesothelioma can also spread to the lymph nodes, causing them to expand.

The majority of people diagnosed with mesothelioma have many years of exposure to asbestos, and are suffering from other diseases like chronic lung diseases. Symptoms of mesothelioma can be similar to other conditions, so it is important to consult a doctor when you observe any persisting or alarming signs and symptoms. Doctors can inquire about asbestos exposure in the past, and then conduct a physical exam. They may also order scans of your body or blood tests of your chest and abdomen. These tests can detect any thickening or fluid between the lungs and chest wall.

Diagnosis

Asbestos fibers that are entangled on the body may cause damage and may eventually grow into cancerous tumours. Different kinds of asbestos-related cancers develop in various tissues or organs and can be identified using different tests. Mesothelioma is found in the lining of the chest cavity and lungs (pleura) as well as the stomach membranes (peritoneum) or around the heart and reproductive organs.

The first step in identifying mesothelioma is to talk with his or her doctor about their history with asbestos exposure and the symptoms they've experienced. Doctors will also conduct a physical exam and request basic tests, such as blood work to determine how well the lungs are working.

X-rays and CT scans help doctors gain a better understanding of the affected area. In certain cases, doctors will use a pleural effusion test to determine if mesothelioma, or another disease is causing fluid buildup in the lung. The pleural effusion could be a symptom of pleural mesothelioma, peritoneal mesothelioma or a rarer form of mesothelioma called biphasic or mixed mesothelioma.

Mesothelioma is often misdiagnosed due to the symptoms resemble those of other diseases and conditions. The most commonly reported symptoms include difficulty breathing and chest pain. Pleural mesothelioma can also cause chest tightness, cough and fatigue. Peritoneal mesothelioma can lead to abdominal discomfort swelling, distension and pain. Testicular mesothelioma may manifest as a swollen or itchy lump that is located in the testicles.

Researchers are studying the presence of certain blood-borne proteins to find an approach to detect mesothelioma earlier in its development. They are also researching several other tests and procedures that may enhance the accuracy of diagnostic tests, including mesothelioma scans and MRIs. They are also researching genetic mutations and ways to determine if a person is at risk of developing mesothelioma through analyzing their family history.

Treatment

Asbestos exposure is the primary risk factor for mesothelioma. People who have been exposed to asbestos, especially in high-risk occupations like electrical work, construction or auto repair, shipbuilding and military service are at an increased risk.

Exposure to asbestos causes mesothelioma, when fibers are trapped in tissue that lines and protects vital organs. The fibers cause DNA damage and irritation to the mesothelium which can cause cancerous cell growth. Mesothelioma symptoms usually do not appear until decades after exposure.

Symptoms differ depending on the type of mesothelioma and the location it develops in the body. Most mesothelioma cases involve the lung lining (pleural mesothelioma) however, it can be found in the lining of the stomach (peritoneal mesothelioma), heart (pericardial mesothelioma) or testicles (testicular mesothelioma).

Mesothelioma staging helps doctors determine treatment options. The disease is classified as stage I through stage IV, with stages I and II being the most early and most manageable. Stage III and IV are the later stages of cancer that are more difficult to treat, but there are many treatment options available.

Pleural mesothelioma is the most frequent form of the disease and affects the lung lining and chest wall, as well as the abdomen. In the majority of cases of pleural mesothelioma asbestos exposure happened in the workplace. This was most likely from breathing in asbestos particles from the air or ingestion of the cancerous substance through the food chain.

Other risk factors include a family history of mesothelioma, genetic mutations, and previous radiation therapy for a different condition. If you've been exposed to asbestos and are suffering from mesothelioma symptoms, it is crucial to see your doctor. Genetic counseling could be beneficial. In certain instances, a mesothelioma specialist can assist you in filing a lawsuit against companies that incorrectly use asbestos in everyday products.
