Understanding the Average Life Expectancy After Mesothelioma Diagnosis | What You Need to Know

Share This Post

Mesothelioma is a rare and aggressive cancer that primarily affects the lining of the lungs, but can also affect other organs such as the heart and abdomen. It is caused by exposure to asbestos, a mineral commonly used in construction materials before its ban in the late 1970s. The disease is known for its long latency period, with symptoms often appearing 20-50 years after initial exposure. This makes mesothelioma particularly difficult to diagnose and treat, leading to an uncertain path for patients and their families.

In this article, we will delve into the complexities of mesothelioma and its impact on life expectancy. We will explore the factors that influence survival rates, the latest advancements in treatment, and strategies for coping with the emotional and practical implications of a mesothelioma diagnosis.

What is Mesothelioma?

Mesothelioma is a type of cancer that develops in the mesothelium, a thin membrane that lines various organs in the body. The most common form of mesothelioma is pleural mesothelioma, which affects the lining of the lungs. Other types include peritoneal mesothelioma (lining of the abdomen), pericardial mesothelioma (lining of the heart), and testicular mesothelioma (lining of the testicles).

The main cause of mesothelioma is exposure to asbestos fibers, which can become lodged in the linings of the organs and cause inflammation and scarring. Over time, this can lead to the development of cancerous cells. Asbestos was widely used in industries such as construction, shipbuilding, and automotive manufacturing before its link to mesothelioma and other health issues was discovered.

Factors Affecting Life Expectancy After Diagnosis

The prognosis for mesothelioma is generally poor, with a median overall survival of 12-21 months. However, several factors can affect an individual’s life expectancy after diagnosis.


Mesothelioma is typically diagnosed in the later stages, as symptoms often do not appear until the cancer has progressed. The stage of mesothelioma at diagnosis is determined by the size and location of the tumor, whether it has spread to nearby lymph nodes, and if it has metastasized to other organs.

In general, the earlier the stage of mesothelioma, the better the prognosis. For example, the 5-year survival rate for stage 1 pleural mesothelioma is around 20%, while the 5-year survival rate for stage 4 is only 5%.


The type of mesothelioma a person has also plays a significant role in their life expectancy. There are three main subtypes: epithelioid, sarcomatoid, and biphasic (a mix of both). Epithelioid mesothelioma tends to have a better prognosis, with a median survival of 18-24 months, while sarcomatoid mesothelioma has a median survival of 6-12 months. Biphasic mesothelioma falls somewhere in between, with a median survival of 10-14 months.

Patient Age and Overall Health

As with most types of cancer, age and overall health can impact a person’s life expectancy after a mesothelioma diagnosis. Younger patients tend to have better outcomes than older patients, as they may be more able to tolerate aggressive treatments. Additionally, patients with pre-existing health conditions or a weakened immune system may have a lower chance of survival.

Treatment Choices

The type of treatment a person receives for mesothelioma can also greatly impact their life expectancy. Currently, there is no cure for mesothelioma, but treatments can help manage symptoms and improve overall quality of life.

  • Surgery: For some patients, surgery may be an option to remove the tumor and surrounding tissues. This is more commonly done for early-stage mesothelioma and can potentially prolong survival.
  • Chemotherapy: Chemotherapy involves using drugs to kill cancer cells and is often used in combination with other treatments. It can help shrink tumors and slow the progression of the disease, but it also comes with significant side effects.
  • Radiation therapy: Radiation therapy uses high-energy rays to target and kill cancer cells. It may be used before or after surgery or as a standalone treatment to help relieve symptoms.
  • Immunotherapy: This form of treatment utilizes the body’s immune system to fight cancer cells. It has shown promise in some patients with mesothelioma, particularly those with epithelioid subtype.
  • Palliative care: Mesothelioma is a complex and challenging disease, and palliative care is crucial in managing symptoms and improving quality of life for patients. This can include pain management, psychological support, and assistance with day-to-day tasks.

The combination and effectiveness of these treatments will vary for each individual, making it difficult to predict exactly how they will impact life expectancy.

Recent Advancements in Treatment and Their Impact

While there is still no cure for mesothelioma, there have been recent advancements in treatment that have shown promising results in extending life expectancy and improving quality of life for patients.

  • Immunotherapy: As mentioned earlier, immunotherapy has shown great potential in treating mesothelioma. One type, called checkpoint inhibitors, works by blocking proteins on cancer cells that prevent the immune system from attacking them. Clinical trials have shown an increased response to treatment and improved survival rates for patients receiving this type of therapy.
  • Targeted therapy: This form of treatment targets specific genetic mutations in cancer cells, preventing them from growing and spreading. While targeted therapy is still in its early stages for mesothelioma, it has shown potential in slowing the progression of the disease.
  • Multimodal therapy: This approach combines two or more types of treatment to attack the cancer from different angles. For example, a patient may receive surgery followed by chemotherapy and radiation therapy. Studies have shown that multimodal therapy can prolong survival in some patients with mesothelioma.

As research and clinical trials continue, there is hope that new treatment options will emerge to improve life expectancy for those diagnosed with mesothelioma.

Coping Strategies and Support

A mesothelioma diagnosis can be emotionally and physically taxing for both the patient and their loved ones. It is important to have a support system and coping strategies in place to help navigate this difficult journey.

  • Build a support network: Reach out to friends and family for emotional support, and consider joining a support group specifically for people with mesothelioma. Connecting with others who are going through a similar experience can be helpful in processing emotions and sharing tips for managing symptoms and treatment.
  • Seek professional counseling: A mesothelioma diagnosis can bring about a range of emotions, including fear, anger, and sadness. Consider seeking professional counseling to help cope with these feelings.
  • Stay active and eat well: Maintaining physical health is crucial in managing symptoms and improving overall quality of life. Talk to your doctor about what types of physical activity are safe and beneficial for you, and try to maintain a healthy diet to provide your body with the nutrients it needs.
  • Address financial concerns: Mesothelioma treatment can be expensive, and many patients may face financial strain. It is important to seek guidance and resources from organizations that offer financial assistance for mesothelioma patients and their families.
  • Plan for end-of-life care: While it may be difficult to think about, making plans for end-of-life care can bring peace of mind and alleviate stress for both the patient and their loved ones. Consider discussing your wishes with family members and creating an advance directive or living will to ensure your wishes are carried out.


Mesothelioma is a complex and aggressive cancer with an uncertain path. While there have been advancements in treatment, there is still no cure, and predicting life expectancy after diagnosis remains challenging. However, by understanding the factors that influence survival rates, staying informed about the latest research and treatment options, and seeking support from loved ones and professionals, patients and their families can navigate this journey with hope and resilience.
