What Causes Mesothelioma Other Than Asbestos
Mesothelioma is a rare form of cancer that develops in the lining of organs, most commonly in the lungs (pleural mesothelioma), abdomen (peritoneal mesothelioma) and less frequently in the heart or testicles. Most cases of mesothelioma are due to asbestos exposure, but a small percentage of those affected develop the disease for other reasons.
Recent studies have revealed other possible causes for the development of this disease.
Understanding these other causes is essential for prevention, early diagnosis and comprehensive treatment.
In this article, What Causes Mesothelioma Other Than Asbestos, we explore the various factors other than asbestos that can lead to mesothelioma.

Understanding mesothelioma:
Before exploring alternative causes, it's important to understand the basics of mesothelioma. This type of cancer primarily affects the thin layer of tissue covering the lungs, abdomen, heart and other internal organs, known as mesothelioma. Mesothelioma is known for its long latency period, with symptoms often not revealing themselves until decades after initial exposure to carcinogens.
The role of asbestos
Asbestos remains the main cause of most cases of mesothelioma. This natural mineral was once widely used in various industries for its heat-resistant and insulating properties. Inhalation or ingestion of asbestos fibers can cause them to penetrate the mesothelium, leading to inflammation, scarring and, ultimately, cancer.
What is asbestos?
Asbestos is a group of minerals known for their heat resistance and durability. Companies used it in thousands of products until the 1980s. Asbestos was popular for decades because it was cheap, strong and fireproof.
Over time, however, it has become increasingly clear that exposure to asbestos is associated with serious health risks. These include asbestos-related cancers such as mesothelioma and lung cancer.
In the 1980s, the United States began tightening regulations on asbestos. However, the risk of exposure to asbestos remains due to past use of this mineral. The United States has not completely banned asbestos. Asbestos is still mined and used in other countries.

Other causes of mesothelioma besides asbestos
Although asbestos exposure is the primary cause of mesothelioma, new research suggests that other factors may also contribute to the development of this disease. Let's look at some of these lesser-known causal factors:
Exposure to erionite:
Eryonite is a naturally occurring mineral that is similar to asbestos but has stronger carcinogenic properties. Exposure to erionite fibers, which are found in some parts of the world, has been linked to an increased risk of mesothelioma. Regions with naturally high levels of erionite, such as parts of Turkey, have seen a higher incidence of mesothelioma.
Similarities and differences between erionite and asbestos
Eryonite and asbestos are needle-shaped fibrous minerals. When inhaled, these fibers can irritate and damage the lining of the lungs, which can lead to the development of mesothelioma. However, there are some important differences:
Chemical composition: Erionite belongs to the zeolite group, while asbestos belongs to the silicate family.
Distribution: Asbestos was commonly used in building materials until the end of the 20th century, leading to widespread exposure. Exposure to erionite is geographically limited.
Radiation Therapy: A rare risk factor
Radiation Therapy is a common treatment for various types of cancer. Although it is very effective, there is a small risk of new cancers, including mesothelioma, developing in the irradiated area. This risk is particularly low in patients receiving standard doses of Radiation Therapy. However, people who have been irradiated with high doses of radiation for certain types of cancer or who received radiation to the chest as a child have a slightly higher risk.
Who has the highest risk of developing mesothelioma after Radiation Therapy?
The risk of developing mesothelioma after radiotherapy is generally low for most patients. However, certain factors can increase the risk:
High radiation doses: receiving a higher dose of radiation than usual increases the risk.
Asbestos exposure: Previous exposure to asbestos significantly increases the risk of mesothelioma after radiation therapy.
Age at the time of Radiation Therapy: People who received chest radiotherapy as children may be slightly more at risk as their bodies are still developing.
Genetic predisposition:
Although rare, genetic mutations can predispose to mesothelioma. Some mesothelioma patients have been found to have inherited genetic defects, such as mutations in the BAP1 gene. These genetic factors can influence susceptibility to the disease and its progression.
Benefits of genetic testing for mesothelioma risk
Genetic testing for mutations in the BAP1 gene can be useful for people with a strong family history of mesothelioma, especially if there is no obvious environmental cause. Early detection of a BAP1 mutation allows for increased mesothelioma screening and potentially earlier diagnosis, leading to better treatment outcomes.
SV40 virus:
Simian virus 40 (SV40), a virus originally found in monkeys, has been implicated as a possible cofactor in the development of mesothelioma. Although controversial, some studies suggest a link between SV40 infection and the development of mesothelioma, particularly in individuals exposed to contaminated polio vaccines in the mid-20th century.
Chronic inflammation
Chronic inflammation, e.g. due to chronic peritonitis or pleurisy, can lead to cellular changes in the mesothelium. Prolonged inflammation can lead to DNA damage and cell transformation and thus contribute to the development of mesothelioma.
Exposure to zeolite:
Like asbestos and erionite, some forms of zeolite minerals have also been linked to an increased risk of mesothelioma. Zeolites are crystalline aluminosilicate minerals commonly used in industry. Inhalation of zeolite fibers, especially in the workplace, can contribute to the development of mesothelioma.
The Importance of Early Diagnosis and Consulting a Doctor
The importance of early diagnosis
Early diagnosis of mesothelioma considerably improves treatment results and survival rates. Due to the aggressive nature of the disease and its long latency period, symptoms often only appear at an advanced stage.
Recognition of early warning signs, such as persistent cough, chest pain, shortness of breath and unexplained weight loss, can lead to earlier medical intervention and a better prognosis.
Regular examinations and screenings, especially for those with known risk factors, are essential for early diagnosis.
Consult a doctor
If you think you may be at risk of mesothelioma, or if you develop symptoms associated with the disease, it's important to seek medical advice immediately.
Specialists such as oncologists and pulmonologists can perform diagnostic tests such as imaging, biopsies and blood tests to determine the presence of mesothelioma.
Early consultation can lead to treatment tailored to the patient's specific condition and needs.
What Causes Mesothelioma Other Than Asbestos: Conclusions
Although asbestos exposure remains the main cause of mesothelioma, other factors such as exposure to erionite, radiation therapy, genetic predisposition and even unknown causes may also play a role.
By knowing about these less common risk factors, you can pay more attention to early diagnosis and consult a doctor if in doubt.
