Condition 101 About Malignant Mesothelioma

What is the definition of Malignant Mesothelioma?

Malignant mesothelioma is an uncommon cancerous tumor. It mainly affects the lining of the lung and chest cavity (pleura) or lining of the abdomen (peritoneum). It is due to long-term asbestos exposure.

What are the alternative names for Malignant Mesothelioma?

Mesothelioma - malignant; Malignant pleura mesothelioma (MPM)

What are the causes for Malignant Mesothelioma?

Long-term exposure to asbestos is the biggest risk factor. Asbestos is a fire-resistant material. It was once commonly found in insulation, ceiling and roofing vinyls, cement, and car brakes. Even though many asbestos workers smoked, experts do not believe smoking itself is a cause of this condition.

Men are affected more often than women. The average age at diagnosis is 60 years. Most people seem to develop the condition about 30 years after being in contact with the asbestos.

What are the symptoms for Malignant Mesothelioma?

Symptoms may not appear until 20 to 40 years or longer after exposure to asbestos, and may include:

  • Abdominal bloating
  • Abdominal pain
  • Chest pain, especially when taking a deep breath
  • Cough
  • Fatigue
  • Shortness of breath
  • Weight loss
  • Fever and sweating

What are the current treatments for Malignant Mesothelioma?

Malignant mesothelioma is a difficult cancer to treat.

There is usually no cure, unless the disease is found very early and the tumor can be completely removed with surgery. Most of the time, when the disease is diagnosed, it is too advanced for surgery. Chemotherapy or radiation may be used to reduce symptoms. Combining certain chemotherapy drugs may help decrease symptoms, but it will not cure the cancer.

Untreated, most people survive about 9 months.

Participating in a clinical trial (test of new treatments), may give the person more treatment options.

Pain relief, oxygen, and other supportive treatments may also help relieve symptoms.

What are the support groups for Malignant Mesothelioma?

You can ease the stress of illness by joining a support group where members share common experiences and problems.

What is the outlook (prognosis) for Malignant Mesothelioma?

The average survival time varies from 4 to 18 months. Outlook depends on:

  • The stage of the tumor
  • The person's age and general health
  • Whether surgery is an option
  • The person's response to treatment

You and your family may want to start thinking about end-of-life planning, such as:

  • Palliative care
  • Hospice care
  • Advance care directives
  • Health care agents

What are the possible complications for Malignant Mesothelioma?

Complications of malignant mesothelioma may include:

  • Side effects of chemotherapy or radiation
  • Continued spread of cancer to other organs

When should I contact a medical professional for Malignant Mesothelioma?

Call for an appointment with your provider if you have symptoms of malignant mesothelioma.

How do I prevent Malignant Mesothelioma?

Avoid exposure to asbestos.
