Mesothelioma – What Causes It?

Mesothelioma is a cancer that affects the lining of organs in the body. Asbestos exposure is a major risk factor for mesothelioma. Asbestos strands that are loose can be absorbed into the lungs and abdomen and attach themselves to sensitive mesothelial cells.

People who have an history of occupational asbestos exposure are at the highest risk, including miners, shipbuilders construction workers, plumbers, electricians, and remodelers of older homes. mesothelioma what to expect of asbestos-exposed individuals are also at a higher risk of risk.

Asbestos Exposure

The majority of mesothelioma cases result from exposure to asbestos, a common material employed in construction and other industries until the late 20th century. After toxicological studies showed asbestos to be carcinogenic in the late 20th century, developed countries began to regulate or ban asbestos (Europe, Australia).

Asbestos is a class of minerals made of microscopic fibers which are extremely tough as well as fire-resistant, heat-resistant and. When disturbed the fibers are able to become airborne and can be absorbed by the body via inhalation or swallowing. They may then get stuck in the mesothelium, which lining the lungs, heart, stomach and other organs. The exposure can last for an extended period of time. Symptoms of mesothelioma typically don’t appear until decades after exposure.

The most prevalent mesothelioma form affects the lungs. In certain instances it may also affect the chest, abdomen or the testis. Most mesothelioma cases involve a type of malignant (cancerous) mesothelial cell growth in the mesothelium. The exact cause of the mutation in these cells is not identified.

The highest risk for asbestos-related illnesses is among those who have been exposed asbestos. This includes people who worked in factories, shipyards and mines and those who handled or installed asbestos-containing materials like roofing or insulation or manual work that came in direct contact with asbestos. Inhaling asbestos dust from secondhand sources is also possible at home, especially when older homes are being renovated or renovated.

A family history of mesothelioma increases the risk of a person developing the disease, as do a person’s smoking habits. Mesothelioma is also more likely to develop if you are genetically predisposed to cancer.

Asbestos patients typically develop mesothelioma in their 50s, 60s or 70s and some patients are diagnosed in their 30s and 40s. They are most often men who were exposed to asbestos at work. One-third to half of mesothelioma sufferers are veterans who were exposed asbestos on military bases, ships, and during construction. Additionally, a small proportion of patients have been exposed to the mineral that occurs naturally talc.


Many asbestos-related illnesses, such as mesothelioma is a genetic disease. Researchers aren’t able to pinpoint exactly how, but mutated genes play a significant role in the development of this cancer. Mutations change a gene’s code, which creates the protein that controls cell growth, duplication and death. The mutations enable cells to become cancerous. Asbestos causes irritation to cells and damages their DNA, which causes mesothelioma to develop.

Mesothelioma can develop in the mesothelium the thin layer of tissue that surrounds most of your body’s internal organs. Three out of four cases begin in the lung (pleural mesothelioma) but it can also affect the abdomen or tissues around the testicles and heart. It’s less common for mesothelioma cases to occur outside of the lungs, however it can happen.

Researchers have examined the connection between mesothelioma and genetics after studying family clusters of the disease. In one instance four members of the same family passed away from malignant mesothelioma. Researchers believe that hereditary factors could have played a role for each of the deceased. Each had a past that involved exposure to asbestos.

A mesothelioma-related gene, BAP1, is frequently mutated in patients who suffer from this disease. This gene controls the body’s self-regulation and ability to kill cancerous cells. When mutated, it allows cancerous mesothelioma cells to grow out of control and spread to other parts of the body.

Patients with this cancer also have mutations in NF2 mesothelioma related gene. This gene controls the way that a protein known as PD-L1 interacts the immune system. If mutated, cancerous gene makes PD-L1 overexpress, which reduces the immune system’s ability fight mesothelioma.

Some patients have an array of environmental and genetic factors that contribute to mesothelioma. They may include the patient’s age as well as the place they were exposed. The older a person was when they were exposed to asbestos the more likely they will be to receive a mesothelioma diagnosis. This is due to the fact that it takes between 20 to 40 years for the disease to develop. Women also tend to have a poorer prognosis for mesothelioma than men.


Mesothelioma is a cancer that is found in the thin layer of tissue that protects most internal organs. A rare type of cancer, mesothelioma is usually fatal if left untreated.

Asbestos exposure is the only known cause of mesothelioma, and it occurs most often when asbestos fibers are absorbed into the lungs. Once inside the lungs, asbestos fibers can become stuck in the lining that surrounds the lungs and chest cavity known as the Pleura. These fibers can irritate the pleura over time, and trigger DNA mutations that can lead to cancerous cells.

The cancer cells multiply out of control and create an abnormality which is the main mesothelioma-related symptom. Other symptoms include chest pain, fatigue and breathing difficulties. As the cancer develops, it may expand to other organs. The most common organ is the lung. Mesothelioma may also affect the abdomen as well as the heart (peritoneal or pericardial mesothelioma).

Many types of asbestos have been utilized in the past for its durability, strength, and fire resistance. People in certain jobs that are exposed to asbestos, including industrial workers, construction workers and veterans of the military, have a higher chance of developing mesothelioma. Asbestos is a class of minerals with thin microscopic fibers that are resistant to heat and do not conduct electricity. It is a naturally-occurring mineral that has been extracted and utilized by a variety of industries.

Researchers have found that chrysotile, amphibole and Erionite asbestos can increase a person’s mesothelioma danger. It isn’t known, however, how asbestos types or levels affect the development of mesothelioma.

Although mesothelioma is not curable but there are options for treatment that can help patients manage their symptoms and extend their lives. Doctors treat the disease with chemotherapy, surgery and radiation therapy. They also provide support to the patient and loved ones. The aim is to keep patients as comfortable as is possible and assist them in achieving their treatment goals and extending their life. Some patients have remarkable survival rates. They are an inspiration to those who are afflicted with this disease.

Environmental Exposure

Asbestos, a naturally occurring mineral is composed of fibers that are strong and resistant to heat. The fibers are able to float in the air for long durations, which makes them easy to inhale or ingest unintentionally. The asbestos-containing particles can irritate organ linings and cause cancer. Mesothelioma is usually found in the lungs, however it can be found in the abdomen or in the heart.

Asbestos can cause mesothelioma because it alters the DNA of the cells that are found in the organs of the body. The mutations that cause cancer can result in tumors that grow and expand. Contrary to other forms of cancer, mesothelioma suffers from a long latency period between exposure to asbestos and appearance of symptoms.

The highest risk of mesothelioma is from occupational asbestos exposure. Workers who work with asbestos on the job such as boiler operators, electricians and shipbuilders, are at the highest risk of developing mesothelioma. However, blue-collar jobs that involved exposure to asbestos in the workplace prior to federal regulations were enacted in the 1970s could also lead to mesothelioma. Some people were exposed to mesothelioma through exposure to asbestos through secondhand sources. These cases involve loved one’s who brought home fibers from their clothing, hair, or shoes after working on an industrial site.

Veterans are another category of people that are at higher risk for mesothelioma. The military has employed asbestos extensively in ships, vehicles and armor. Different types of asbestos have been employed in the military, but chrysotile was especially connected to mesothelioma.

Genetics and radiation are also risk factors for mesothelioma. BAP1 gene mutations increase the risk of mesothelioma, as well as other diseases. The gene regulates cell growth and may help in preventing the growth of tumors. Exposure to radioactive substances like thorium dioxide, which was used as a component of X-rays in imaging tests between the 1920s and 1950s increases the risk of developing mesothelioma. The BAP1 gene mutation is also associated with melanoma in the eye and skin.
