Malignant Mesothelioma is a rare and aggressive form of cancer that affects the lining of the lungs, abdomen, or heart. The main risk factor for developing this disease is exposure to asbestos fibers, a naturally occurring mineral commonly used in the past in the construction and shipbuilding industries.

It can take several decades to develop. Symptoms include shortness of breath, chest pain, and abdominal swelling. The prognosis is generally poor, with limited treatment options and a median survival time of less than a year.

Other potential risk factors include:

  1. Asbestos exposure
  2. Smoking
  3. Age (typically over 60 years)
  4. Gender (more common in men)
  5. Family history
  6. Occupational exposure (e.g. in construction, shipyard work)
  7. Inflammatory lung disease.
  1. Exposure to asbestos: This is the most significant risk factor for malignant mesothelioma. People who have been exposed to asbestos fibers over a long period of time, such as workers in asbestos mines, construction workers, shipyard workers, and insulation workers, are at an increased risk.
  2. Duration and intensity of asbestos exposure: The longer and more intense a person’s exposure to asbestos, the higher their risk of developing mesothelioma.
  3. Age: Malignant mesothelioma is more common in older individuals, typically those over the age of 60.
  4. Gender: Men are more likely to develop mesothelioma than women, likely due to the higher number of men who have been exposed to asbestos in occupational settings.
  5. Smoking: Smoking does not directly cause mesothelioma, but it does increase the risk for people who have been exposed to asbestos.
  6. Family history: There may be a genetic predisposition to developing mesothelioma, as some families have a higher incidence of the disease.
  7. Other exposures: People who have been exposed to erionite, a naturally occurring mineral that is similar to asbestos, are at an increased risk of developing mesothelioma. Additionally, individuals who have been exposed to other types of dust and fibers may also have an increased risk.
  8. Occupational exposure: People who have worked in industries where asbestos was used, such as construction, shipbuilding, and manufacturing, are at an increased risk of developing mesothelioma.
  9. Chronic pleural effusion: People who have had a long-standing fluid buildup around their lungs (pleural effusion) are at an increased risk of developing mesothelioma.
  10. Previous radiation therapy: People who have undergone radiation therapy for other types of cancer are at an increased risk of developing mesothelioma.

Treatment for Malignant Mesothelioma

Malignant mesothelioma is a rare and aggressive cancer that affects the mesothelial cells that line the lungs, abdomen, and heart. Treatment options for malignant mesothelioma include:

  1. Surgery: including pleurectomy/decortication (removal of the pleural lining) or extrapleural pneumonectomy (removal of the entire lung and part of the diaphragm).
  2. Radiation therapy: using high-energy rays to kill cancer cells.
  3. Chemotherapy: using drugs to kill cancer cells.
  4. Immunotherapy: using drugs to boost the body’s natural immune response to cancer.
  5. Clinical trials: exploring new and innovative treatments that are not yet widely available.

The choice of treatment will depend on several factors, including the stage and location of the cancer, the patient’s overall health, and the patient’s personal preferences. A multidisciplinary team of specialists, including a mesothelioma specialist, oncologist, surgeon, and radiologist, will work together to develop a treatment plan tailored to the individual patient.


  1. Avoid Exposure to Asbestos: The primary cause of malignant mesothelioma is exposure to asbestos, so avoiding exposure to this hazardous substance is the most effective way to prevent the disease.

  2. Use Protective Gear: If you work in an environment where asbestos exposure is a possibility, it is important to use protective gear such as masks, gloves, and eye protection.

  3. Get Regular Health Checks: If you have been exposed to asbestos in the past, it is recommended that you undergo regular health checks to monitor for any early signs of mesothelioma.

  4. Safe Demolition Practices: When demolishing buildings that contain asbestos, it is important to follow safe demolition practices to minimize the release of asbestos fibers into the air.

  5. Use Alternative Products: There are alternative building materials that can be used instead of asbestos. Use these materials to reduce the risk of asbestos exposure.

  6. Educate Yourself: Educate yourself on the dangers of asbestos and the steps you can take to reduce your risk of exposure. Share this information with others to help prevent mesothelioma.

  7. Support Research: Support research into mesothelioma and the development of new treatments. Your support can help bring hope to those affected by this disease.
