What is Mesothelioma?
Mesothelioma is a rare and aggressive form of cancer that affects the thin layer of tissue that covers the lungs, chest wall, abdomen, and other organs. This tissue is known as the mesothelium, and mesothelioma most commonly occurs in the lining of the lungs, which is called the pleura.
Mesothelioma is caused by exposure to asbestos, a natural mineral that was once widely used in construction, shipbuilding, and other industries. When asbestos fibers are inhaled or ingested, they can become lodged in the mesothelium and cause damage to the cells, which can lead to mesothelioma.
| Type | Incidence | Mortality |
|---|---|---|
| Pleural Mesothelioma | 70% | 80% |
| Peritoneal Mesothelioma | 20% | 50% |
| Pericardial Mesothelioma | 1% | 90% |
| Testicular Mesothelioma | Less than 1% | N/A |
What are the Symptoms of Mesothelioma?
The symptoms of mesothelioma can vary depending on the type and stage of the cancer, but may include:
- Chest pain or discomfort
- Shortness of breath
- Coughing or wheezing
- Fatigue or weakness
- Loss of appetite or weight loss
- Nausea or vomiting
- Sweating
- Fever
If you are experiencing any of these symptoms and have a history of asbestos exposure, it’s important to see a doctor as soon as possible.
How is Mesothelioma Diagnosed?
Diagnosing mesothelioma can be challenging because the symptoms are similar to those of other conditions, and because it is a rare disease. Your doctor may use a combination of tests and procedures to diagnose mesothelioma, including:
- Chest X-ray
- CT scan
- MRI
- PET scan
- Blood tests
- Biopsy
A biopsy is the only way to confirm a diagnosis of mesothelioma. During a biopsy, a small piece of tissue is removed from the affected area and examined under a microscope.
Types of Mesothelioma
There are four main types of mesothelioma, which are classified based on the location of the cancer:
- Pleural mesothelioma: This is the most common type of mesothelioma, and affects the lining of the lungs.
- Peritoneal mesothelioma: This type of mesothelioma affects the lining of the abdomen.
- Pericardial mesothelioma: This rare type of mesothelioma affects the lining of the heart.
- Testicular mesothelioma: This is the rarest type of mesothelioma, and affects the lining of the testicles.
What are the Symptoms of Pleural Mesothelioma?
The symptoms of pleural mesothelioma may include:
- Chest pain or discomfort
- Shortness of breath
- Coughing or wheezing
- Fatigue or weakness
- Loss of appetite or weight loss
What are the Symptoms of Peritoneal Mesothelioma?
The symptoms of peritoneal mesothelioma may include:
- Abdominal pain or swelling
- Nausea or vomiting
- Loss of appetite or weight loss
- Bowel changes
What are the Symptoms of Pericardial Mesothelioma?
The symptoms of pericardial mesothelioma may include:
- Chest pain or discomfort
- Shortness of breath
- Persistent cough
- Heart palpitations
What are the Symptoms of Testicular Mesothelioma?
The symptoms of testicular mesothelioma may include:
- Swelling or lump in the testicle
- Pain or discomfort in the testicle or scrotum
Causes of Mesothelioma
Mesothelioma is caused by exposure to asbestos, a naturally occurring mineral that was once widely used in construction, shipbuilding, and other industries. When asbestos fibers are inhaled or ingested, they can become lodged in the mesothelium and cause damage to the cells, which can lead to mesothelioma.
Asbestos exposure can occur in a variety of ways, including:
- Working with asbestos-containing products
- Living or working in a building that contains asbestos
- Living with someone who works with asbestos
- Working in an industry with high levels of asbestos exposure
It’s important to note that not everyone who is exposed to asbestos will develop mesothelioma, and that the risk increases with the duration and intensity of the exposure.

What are the Stages of Mesothelioma?
Mesothelioma is staged based on the extent of the cancer and how far it has spread. The stages of mesothelioma are:
- Stage 1: Cancer is localized to one side of the chest and has not spread to other parts of the body.
- Stage 2: Cancer has spread beyond the point of origin and may have spread to nearby lymph nodes.
- Stage 3: Cancer has spread to nearby organs and lymph nodes, and may be affecting the other side of the chest.
- Stage 4: Cancer has spread throughout the body and is affecting multiple organs.
The stage of your mesothelioma will play a role in determining your treatment options and prognosis.

What are the Treatment Options for Mesothelioma?
Treatment for mesothelioma depends on the type and stage of the cancer, as well as your overall health and other factors. Some common treatment options for mesothelioma include:
- Surgery
- Chemotherapy
- Radiation therapy
- Immunotherapy
In some cases, a combination of treatments may be used to achieve the best possible outcome.
What is the Prognosis for Mesothelioma?
The prognosis for mesothelioma depends on many factors, such as the type and stage of the cancer, and the patient’s overall health. Mesothelioma is a serious and often aggressive form of cancer, but early diagnosis and treatment can improve the chances of a positive outcome.

Surgery for mesothelioma involves removing as much of the cancerous tissue as possible. Depending on the location and extent of the cancer, different types of surgery may be used, such as:
- Pleurectomy and decortication (P/D)
- Extrapleural pneumonectomy (EPP)
- Peritonectomy
Surgery is often used in combination with other treatments, such as chemotherapy and radiation therapy.

Chemotherapy involves the use of drugs to kill cancer cells or slow their growth. Chemotherapy may be given orally or intravenously, and is often used in combination with other treatments, such as surgery and radiation therapy.
What is Radiation Therapy for Mesothelioma?
Radiation therapy involves the use of high-energy radiation to kill cancer cells or slow their growth. Radiation therapy may be given externally or internally, and is often used in combination with other treatments, such as surgery and chemotherapy.
What is Immunotherapy for Mesothelioma?
Immunotherapy involves the use of drugs that help the body’s immune system fight cancer. Immunotherapy may be used alone or in combination with other treatments, such as chemotherapy and radiation therapy.

Some factors that may affect the prognosis for mesothelioma include:
- The type and stage of the cancer
- The location and size of the tumor
- The patient’s age and overall health
- The presence of other medical conditions
Your doctor can provide more specific information about your prognosis based on your individual situation.
Prevention of Mesothelioma
The best way to prevent mesothelioma is to avoid exposure to asbestos. If you work in an industry where asbestos is present, make sure you follow all safety procedures and wear appropriate protective gear. If you live in a building that contains asbestos, consult with a professional to have it safely removed or contained.
If you have been exposed to asbestos in the past, it’s important to monitor your health and see a doctor if you experience any symptoms of mesothelioma.
