Mesothelioma Causes Other Than Asbestos

Mesothelioma occurs in the tissues that line the chest wall, lungs abdomen, and other organs. People who get this cancer usually worked on jobs that exposed them to asbestos.

Asbestos is a class of minerals that make strong microscopically-sized fibers. It was used to make construction and automotive products as it is invulnerable to fire, heat and water.

Occupational Exposure

Asbestos is a naturally occurring mineral that was used extensively to protect against fire before it was banned in the 1970s. People who worked with asbestos regardless of whether they mined it or worked with it in factories are at risk of developing mesothelioma. The people who are at the highest risk are those who were exposed to large quantities of microscopic asbestos fibers for prolonged periods of time. Mesothelioma symptoms generally don't manifest until decades after exposure to asbestos. This is why the majority of mesothelioma cases are linked to occupational asbestos exposure.

When asbestos is disturbed, its tiny fibers can become airborne and can be breathed in or swallowed. The fibers could make their way to the thin layer of tissue that surrounds organs. This layer is known as the mesothelium, and it is prone to developing mesothelioma-related cancerous tumors. Pleural mesothelioma is a tumor that develops around the lung and is the most prevalent mesothelioma form. Other mesothelioma types are pericardial and peritoneal. They are formed in the abdomen.

Mesothelioma can also occur in other parts of the body, if asbestos is ingested or inhaled with smaller amounts. It can develop in the testicles' linings and the abdominal cavity. Mesothelioma is typically the result of an injury to the mesothelium and it's difficult to determine whether it was caused by exposure to occupational radiation or a different cause.

Certain mesothelioma patients have developed the disease through contact with asbestos from the outside. This is often referred to as take-home exposure, and occurs when asbestos is brought home on the clothing of workers or other equipment. In these situations families are often required to clean and wash the workers' clothes which can lead to greater exposure than would otherwise be expected. Some studies have found that the use of a similar asbestos known as erionite increases the risk of mesothelioma developing in those who live near erionite deposits.

Radiation and chemotherapy are also medical treatments that can increase the risk of developing mesothelioma. These treatments can damage mesothelium, causing mesothelioma, but they do not account for a large proportion of cases.

Secondhand Exposure

Many other factors can increase a person's chance of developing mesothelioma. These include genetics, a history of radiation therapy to the chest and secondhand exposure. A family history of the disease may also increase an individual's risk. However, asbestos remains the primary mesothelioma cause.

Workers who are directly exposed to asbestos are at the greatest risk of developing mesothelioma. This is particularly true for those who work in manufacturing, construction, shipbuilding, asbestos lawsuit mining, and other related industries. People who work with asbestos often inhale tiny asbestos fibers when they break or disturb the substance. The asbestos fibers can end up in the linings of the lungs, stomach and the heart. The asbestos litigation may remain in the body for a long time, causing malignant mesothelioma tumors to develop.

Inhaling or swallowing these harmful fibers could lead to mesothelioma pleural, peritoneal mesot and other forms of the disease. The symptoms can take between 30 to 50 years to show. To determine if mesothelioma is a cancer doctors must first rule out any other condition that could be causing the patient's symptoms.

Exposure to asbestos is known to cause pleural mesothelioma, the most common type of cancer. It is believed that the risk for this form of mesothelioma diminishes after a person's asbestos exposure is over. However, the risk of mesothelioma of the peritoneal region continues to increase even after exposure to asbestos has ended.

Asbestos is a class of naturally occurring metamorphic minerals that are fibrous. It is highly robust and is resistant to fire and heat which makes it a popular choice for industrial, military and commercial applications throughout the 20th century. Asbestos was heavily used from the end of World War II through to the mid 1970s. It was commonly used in ship, buildings as well as in automobile parts and insulation.

Workers who handled or inhale asbestos were the primary group that developed mesothelioma. However, some people have been diagnosed with mesothelioma and do not have a history of occupational exposure to asbestos. These individuals were exposed to asbestos through other methods. For example, many wives of husbands who employed asbestos brought home stray asbestos fibers that landed on their clothing and skin. Those who were vaccinated against polio in the 1950s and 1960s were found to be at an increased risk of developing mesothelioma too because of the contamination of the vaccine for polio with asbestos law.

Environmental Exposure

While asbestos is the main mesothelioma trigger but there are a variety of other factors that could be involved. This may include the person's gender, age, or genetics. People with a genetic predisposition or other health issues are more at risk of developing mesothelioma than those who don't.

Exposure to asbestos in the workplace is responsible for the majority of mesothelioma cases. Workers who have long-term, constant exposure to asbestos, like shipyard or miners workers, are at most risk. However, many of those with mesothelioma have not directly worked with asbestos. The risk of exposure to asbestos can be exacerbated when someone lives with someone who worked with asbestos and breathe in asbestos fibers. This type of exposure is the most frequent among spouses of those who worked with asbestos compensation.

Mesothelioma symptoms typically occur over time and differ depending on the type of mesothelioma that a person has. It is important for everyone to be aware of the risks and consult a physician if they are experiencing any unusual or worrying symptoms.

Asbestos exposure can lead to three kinds of mesothelioma: Pericardial, peritoneal, and pleural. Pleural mesothelioma affects the lungs, peritoneal mesothelioma affects organs in the abdomen, and mesothelioma of the pericardium is a common occurrence heart. Most mesothelioma forms in the lung. However, peritoneal and pericardial cancers can also develop in the abdominal cavity.

Researchers have discovered that different substances can cause mesothelioma too. This includes erionite, which is a mineral similar to asbestos, and radiation therapy. In addition, a virus known as SV40 and certain kinds of talcum powder can also cause mesothelioma.

The study of the causes of mesothelioma help doctors make diagnoses more quickly and precisely. This allows mesothelioma sufferers to receive treatment earlier and improve their results. It is also essential to understand other mesothelioma risk factors to help to avoid more mesothelioma cases in the near future. The use of talcum could increase the risk of women developing peritoneal cancer. Through educating the public about mesothelioma, we can decrease the number of patients diagnosed with the disease. This is particularly important as mesothelioma symptoms are typically delayed for as long as 50 years.

Genetics

If you have been diagnosed with mesothelioma, you should consult a physician. Early treatment can give patients the best prognosis. While asbestos exposure is the most common mesothelioma cause but research continues to identify other risk factors such as talcum powder and SV40. Knowing and avoiding these risk factors can help reduce the incidence of mesothelioma.

Asbestos is a class of fibrous minerals that were used extensively throughout the 20th century for various industrial, commercial and military applications. Its strength and fire resistance was a major draw for manufacturers. However, the dangers of asbestos became evident and were documented by researchers, resulting in its phase out. The people who were exposed to asbestos in the workplace are at risk for mesothelioma. This includes miners factory workers, asbestos insulation manufacturers and installers, railroad workers, ship builders, auto manufacturers and others who handled or wore clothing contaminated with asbestos.

Inhaled asbestos fibers settle in the lung's lining (the pleura) and are irritation and eventually grow into tumors. The symptoms typically take years to manifest, but by the time they do, mesothelioma is already advanced. Symptoms can include chest pain, heaviness, or difficulty breathing. Fluid buildup in the lungs is also an indication.

Mesothelioma results from cancerous cell mutations. These are due to asbestos exposure, however many scientists believe a person's genes also play an important role. Researchers have discovered a gene named BAP 1, located on the short arm chromosome 3, that causes mesothelioma. They discovered this gene through studying epidemics of mesothelioma in two U.S. family with Swiss origins. The mutation in the gene was discovered in every member of the family who had mesothelioma.

Genetics is only one aspect of the mesothelioma puzzle, but it is a crucial one. A small proportion of those who suffer from asbestos exposure develop mesothelioma, which suggests that a person's genes may also be at play. The genes that suppress tumors appear to be altered in the majority mesothelioma victims. As the research continues this gene will be investigated and analyzed better to prevent further mesothelioma developing. It is also possible that those who are genetically predisposed will need to be more careful about asbestos exposure and will need regular screening for mesothelioma signs.
