The Truth About Mesothelioma | Understanding Average Life Expectancy

Share This Post

Mesothelioma is a rare and aggressive form of cancer that primarily affects the lining of the lungs. It is caused by exposure to asbestos, a mineral once widely used in construction and other industries. This disease has a long latency period, often taking decades to manifest after initial exposure. As a result, it casts a long shadow over the lives of those affected, leaving a lasting impact on their health and life expectancy.

In this article, we will delve into the realities of mesothelioma and its impact on life expectancy. We will explore the average life expectancy for mesothelioma patients, as well as the factors that influence it. Additionally, we will discuss treatment options and strategies for extending life expectancy, as well as the role of research and innovation in seeking new treatments. By the end, we hope to provide a comprehensive guide for patients and families dealing with the devastating effects of mesothelioma and its implications for life expectancy.

Average Life Expectancy for Mesothelioma: A Comprehensive Overview

The prognosis for mesothelioma is generally poor, with a median survival time ranging from 12 to 21 months. This means that half of mesothelioma patients will live for less than two years after diagnosis. However, it is important to note that every case is unique, and some patients may live longer or shorter than the average life expectancy.

Several factors can influence life expectancy in mesothelioma patients, including the stage of diagnosis, type of mesothelioma, age, overall health, and access to quality healthcare. Let’s dive deeper into each of these factors and understand their impact on life expectancy.

Factors Influencing Life Expectancy in Mesothelioma Patients

Stage of Diagnosis

As with most cancers, early detection plays a significant role in increasing life expectancy in mesothelioma patients. In cases where the cancer is diagnosed in its early stages, when it is still localized and hasn’t spread to other parts of the body, there is a better chance for successful treatment and a longer life expectancy.

Unfortunately, mesothelioma is often diagnosed in its later stages when the cancer has already metastasized, making it difficult to treat and reducing the chances of extending life expectancy. According to data from the National Cancer Institute, the five-year survival rate for localized mesothelioma is 18%, while the survival rate for metastatic mesothelioma drops to just 1%.

Type of Mesothelioma

There are four types of mesothelioma based on the location of the cancer: pleural (in the lining of the lungs), peritoneal (in the lining of the abdomen), pericardial (in the lining of the heart), and testicular (in the lining of the testicles). The type of mesothelioma can also influence life expectancy, with peritoneal mesothelioma having a better prognosis than the other types.

This is because peritoneal mesothelioma is more responsive to certain treatments, such as surgery and heated chemotherapy, which have been found to improve survival rates and extend life expectancy. On the other hand, pleural mesothelioma is the most common type, and it tends to have a poorer prognosis due to its location and difficulty to treat.

Age and Overall Health

Age and overall health play a role in determining life expectancy for mesothelioma patients. Generally, older patients tend to have a lower life expectancy compared to younger patients due to a weaker immune system and other age-related health factors. Additionally, patients with preexisting health conditions may have a lower life expectancy due to the added strain on their bodies from both the disease and its treatment.

Diagnosis and Prognosis: Assessing Life Expectancy with Mesothelioma

Diagnosing mesothelioma can be challenging due to its long latency period and the similarity of its symptoms to other respiratory conditions. As a result, patients are often diagnosed in the later stages of the disease, when treatment options are limited, and life expectancy is significantly reduced.

The most common diagnostic tools include imaging scans, such as X-rays, CT scans, and MRIs, which help identify the presence and location of tumors. Biopsies, where a small sample of tissue is taken for analysis, are also used to confirm a diagnosis of mesothelioma.

Once a diagnosis is confirmed, doctors use various factors to determine the prognosis and estimate life expectancy. This includes the stage of the cancer, the type and location of the tumor, and the overall health of the patient.

Treatment Options and Their Impact on Life Expectancy

Currently, there is no cure for mesothelioma, but several treatment options can help extend life expectancy and improve the quality of life for patients. These include surgery, chemotherapy, radiation therapy, immunotherapy, and targeted drug therapy. However, the effectiveness of these treatments may vary depending on the type and stage of mesothelioma, as well as the individual’s overall health.


Surgery is often the first-line treatment for early-stage mesothelioma, where the cancer is still localized and hasn’t spread significantly. The goal of surgery is to remove as much of the cancerous tissue as possible, reducing the tumor burden and potentially extending life expectancy. There are different types of surgeries used to treat mesothelioma, including:

  • Pleurectomy and decortication (P/D): This is a lung-sparing surgery that involves removing the diseased pleural lining and any visible tumors.
  • Extrapleural pneumonectomy (EPP): This is a more invasive surgery that involves removing the entire lung, the pleural lining, and other affected tissues, such as the diaphragm and pericardium.
  • Cytoreductive surgery (CRS): This surgery is used to treat peritoneal mesothelioma and involves removing all visible tumors from the peritoneum.
  • Testicular mesothelioma surgery: Treatment for this type of mesothelioma often involves surgical removal of the affected testicle.

Surgery can improve life expectancy and quality of life for some mesothelioma patients. However, it may not be an option for everyone, especially those in later stages or with other underlying health conditions.


Chemotherapy is a systemic treatment that uses drugs to kill cancer cells or slow their growth. It is usually administered intravenously or in pill form and can be used as a primary treatment or alongside surgery. Chemotherapy can help extend life expectancy by shrinking tumors and slowing the progression of the disease.

For peritoneal mesothelioma, heated chemotherapy (also known as hyperthermic intraperitoneal chemotherapy or HIPEC) is often used. This involves delivering heated chemotherapy directly into the abdominal cavity during surgery, which helps kill any remaining cancer cells and reduces the risk of recurrence.

Radiation Therapy

Radiation therapy uses high-energy beams such as X-rays and protons to kill cancer cells and shrink tumors. It is often used as a palliative treatment in mesothelioma, helping to relieve symptoms like pain and difficulty breathing. In some cases, it may also be used alongside surgery or chemotherapy to improve the effectiveness of treatment and potentially extend life expectancy.


Immunotherapy is a relatively new form of treatment that harnesses the body’s immune system to fight cancer. It can help extend life expectancy in some mesothelioma patients by boosting the body’s natural defenses against the disease. Types of immunotherapy used in mesothelioma treatment include:

  • Checkpoint inhibitors: These drugs help “release the brakes” on the immune system, allowing it to recognize and attack cancer cells.
  • CAR T-cell therapy: This is a personalized form of immunotherapy where immune cells are extracted from the patient’s blood, genetically modified to target cancer cells, and then reinfused into the body.
  • Cytokines: These are naturally occurring proteins that can stimulate the immune system to fight cancer cells.

Targeted Drug Therapy

Targeted drug therapy uses drugs that specifically target certain molecules or pathways involved in cancer growth and spread. They tend to have fewer side effects than traditional chemotherapy and may be more effective in some cases. Some targeted therapies currently being studied for use in mesothelioma treatment include:

  • Angiogenesis inhibitors: These drugs block the formation of new blood vessels, which are necessary for tumors to grow and spread.
  • PARP inhibitors: These drugs can prevent cancer cells from repairing DNA damage, leading to their death.
  • EGFR inhibitors: These drugs block the activity of a protein called EGFR, which is overexpressed in many types of cancer, including mesothelioma.

The Role of Stage and Histology in Mesothelioma Life Expectancy

As discussed earlier, the stage of mesothelioma at diagnosis can have a significant impact on life expectancy. Generally, the earlier the stage, the better the prognosis and the longer the life expectancy. Doctors use different staging systems to classify mesothelioma based on how far the cancer has spread and guide treatment decisions. The most common staging systems for mesothelioma include TNM (tumor, lymph nodes, metastasis), Brigham, and Butchart.

Another important factor is the histology, or the type of cancer cells involved. There are three main histological subtypes of mesothelioma: epithelioid, sarcomatoid, and biphasic. Epithelioid mesothelioma is the most common subtype, with a better prognosis than sarcomatoid and biphasic mesothelioma.

Living with Mesothelioma: Strategies to Extend Life Expectancy

While there is no cure for mesothelioma, there are ways to manage the disease and improve life expectancy. Alongside traditional medical treatments, patients are encouraged to adopt healthy lifestyle habits that can help them cope with the disease and potentially extend their life expectancy. Some of these strategies include:

  • Staying physically active: Regular exercise can improve overall health and reduce the risk of developing other health conditions.
  • Eating a balanced diet: A nutritious diet can help boost the immune system and provide the body with the necessary nutrients to fight the disease.
  • Managing symptoms: Mesothelioma can cause a range of symptoms, such as pain, difficulty breathing, and fatigue. Managing these symptoms through medication, therapy, or alternative treatments can help improve quality of life and potentially extend life expectancy.
  • Seeking emotional support: Dealing with a cancer diagnosis can be emotionally taxing for both patients and their families. It is essential to seek support from loved ones, as well as mental health professionals, to cope with the emotional toll of the disease.
  • Participating in clinical trials: Clinical trials are research studies that test new treatments for various diseases, including mesothelioma. By participating in a clinical trial, patients may have access to cutting-edge treatments and potentially extend their life expectancy.

Hope and Support: Navigating Life Expectancy with Mesothelioma

A diagnosis of mesothelioma can be devastating, but it is essential to remember that there is always hope. While the average life expectancy for mesothelioma may be low, every person’s journey is unique, and some patients have been known to exceed their life expectancy. Additionally, advancements in research and treatment are constantly being made, offering hope for improved survival rates and better quality of life for mesothelioma patients.

It is also crucial for patients and their families to seek support and guidance throughout the journey. There are various resources available, including support groups, patient advocacy organizations, and legal assistance for those seeking compensation for their exposure to asbestos.

Research and Innovation: Seeking New Treatments and Extending Life Expectancy

Research plays a critical role in improving our understanding of mesothelioma and developing new and effective treatments. Currently, there are numerous ongoing clinical trials studying potential treatments for mesothelioma, including new drug therapies, immunotherapies, and novel surgical techniques.

Additionally, researchers are working on improving early detection methods for mesothelioma, which can significantly impact life expectancy by allowing for earlier treatment. Some studies are also focusing on identifying biomarkers that can help predict disease progression and guide treatment decisions.
