Malignant Mesothelioma Symptoms: Everything You Need to Know :

Greetings, everyone. If you or someone you know has been diagnosed with malignant mesothelioma, it’s essential to understand the symptoms associated with this rare and aggressive form of cancer. In this article, we will dive deep into everything you need to know about malignant mesothelioma symptoms, including its causes, stages, diagnosis, and treatment.

What is Malignant Mesothelioma?

Malignant mesothelioma is a rare and aggressive form of cancer that affects the mesothelium, a protective lining that covers the internal organs of the body. The most common form of mesothelioma affects the lining of the lungs or pleura, which is called pleural mesothelioma. Other less common forms of mesothelioma include peritoneal mesothelioma (abdomen), pericardial mesothelioma (heart), and testicular mesothelioma (testicles).

What are the Causes of Malignant Mesothelioma?

The primary cause of malignant mesothelioma is exposure to asbestos, a naturally occurring mineral that was widely used in construction, shipbuilding, and other industries until the mid-1970s. Asbestos fibers are tiny and can easily be inhaled or swallowed, where they can become lodged in the mesothelium and lead to cancerous growth.

Other potential causes of malignant mesothelioma include genetic mutations, radiation exposure, and simian virus 40 (SV40) infection. However, these risk factors are relatively rare and only account for a small percentage of mesothelioma cases.

What are the Symptoms of Malignant Mesothelioma?

The symptoms of malignant mesothelioma can vary depending on the location of the cancer and its stage of development. Common symptoms of pleural mesothelioma include:

Symptoms of Pleural Mesothelioma Symptoms of Peritoneal Mesothelioma
Chest pain Abdominal pain
Shortness of breath Abdominal swelling
Coughing Nausea and vomiting
Fatigue Loss of appetite
Unexplained weight loss Constipation or diarrhea

Pericardial mesothelioma can cause chest pain, difficulty breathing, and irregular heartbeats, while testicular mesothelioma can cause swelling or lumps in the testicles.

How is Malignant Mesothelioma Diagnosed?

Diagnosing malignant mesothelioma can be challenging because its symptoms mimic other more common conditions. A medical history, physical exam, and imaging tests such as X-rays, CT scans, and MRIs are usually the first steps in detecting mesothelioma. Doctors may also use a biopsy to collect a tissue sample for laboratory testing to confirm the diagnosis.

What are the Stages of Malignant Mesothelioma?

There are four stages of mesothelioma, with stage 1 being the earliest and most treatable stage and stage 4 being the most advanced and least treatable stage. The stages are determined by the size of the tumor, its location, and whether it has spread to other parts of the body.

How is Malignant Mesothelioma Treated?

The treatment options for mesothelioma depend on the stage of the cancer, its location, and the patient’s overall health. The three most common treatments for mesothelioma are surgery, chemotherapy, and radiation therapy. Combination therapies that involve a combination of these treatments may also be used.

FAQs About Malignant Mesothelioma Symptoms

Q: What is the difference between mesothelioma and lung cancer?

A: While mesothelioma and lung cancer can have similar symptoms, they are two distinct types of cancer that affect different parts of the body. Mesothelioma affects the mesothelium, which is a lining around the organs in the chest and abdomen, while lung cancer affects the lung tissue itself.

Q: Who is at risk for mesothelioma?

A: The primary risk factor for mesothelioma is exposure to asbestos, which can occur in various occupations such as construction, shipbuilding, and industrial workers. Family members of those who work with asbestos can also be exposed to the fibers through secondhand exposure.

Q: Can mesothelioma be cured?

A: While there is no known cure for mesothelioma, early detection and treatment can significantly improve a patient’s quality of life and increase their life expectancy. Treatment options can include surgery, chemotherapy, and radiation therapy, as well as ongoing monitoring and management of symptoms.

Q: What is the life expectancy for someone with mesothelioma?

A: Life expectancy for mesothelioma patients can vary widely depending on the stage of the cancer, the location, and the patient’s overall health. On average, the life expectancy for someone diagnosed with mesothelioma is around 12 to 21 months.

Q: Can mesothelioma be prevented?

A: The best way to prevent mesothelioma is to avoid exposure to asbestos. Employers should take steps to protect workers from asbestos exposure, such as providing personal protective equipment and following safety regulations. Homeowners should also avoid disturbing asbestos-containing materials in their homes.


Malignant mesothelioma is a rare but aggressive form of cancer that can be challenging to diagnose and treat. Understanding the symptoms associated with mesothelioma is essential for early detection and improved patient outcomes. If you or someone you know is experiencing symptoms associated with malignant mesothelioma, seek medical attention immediately.
