Mesothelioma Causes and Symptoms: Everything You Need to Know

📗 Mesothelioma is a rare and deadly cancer that affects the lining of the lungs, heart, and abdomen. It is caused by exposure to asbestos, a group of naturally occurring minerals that were widely used in construction materials for decades.

Despite laws and regulations to prohibit the use of asbestos, many buildings and products still contain the mineral, putting individuals at risk of developing mesothelioma. In this article, we will discuss the causes and symptoms of mesothelioma, as well as how to seek treatment and support.

The Basics: What is Mesothelioma?

Mesothelioma is a type of cancer that affects the mesothelium, a protective lining that covers the organs in the body. The cancer typically develops in the lining of the lungs, but can also form in the lining of the heart or abdomen.

📗 The most common cause of mesothelioma is exposure to asbestos, which can occur through inhalation or ingestion of the minerals. Once in the body, the asbestos fibers can irritate and damage the mesothelial cells, leading to the development of cancer.

Mesothelioma Causes: How Does Asbestos Exposure Occur?

Asbestos was commonly used in construction and manufacturing products due to its durability and heat-resistant properties. Workers who were exposed to asbestos in their occupations, such as miners, insulation workers, shipbuilders, and construction workers, are at a higher risk of developing mesothelioma.

📗 Asbestos can also be found in older buildings and homes, where it may have been used in insulation, roofing, and other construction materials. Disturbing these materials can release asbestos fibers into the air, putting individuals at risk of exposure.

Mesothelioma Symptoms: What Are the Signs of the Disease?

Early symptoms of mesothelioma are often vague and can be mistaken for other conditions. However, as the cancer progresses, more severe symptoms may develop.

📗 Common mesothelioma symptoms include:

Symptom Description
Chest pain Pain in the chest or rib area that becomes more severe with deep breathing or coughing.
Shortness of breath Difficulty breathing or gasping for air, even during routine activities.
Fatigue Feeling tired or weak, even after getting enough rest.
Coughing Persistent dry or wheezing cough that does not go away.
Lumps under the skin Small, painless nodules that develop under the skin.
Abdominal swelling Swelling or bloating of the abdomen, with or without pain.
Nausea and vomiting Feeling sick to the stomach, with or without vomiting.

How is Mesothelioma Diagnosed?

As mesothelioma symptoms can be similar to those of other conditions, a medical professional will typically perform a series of tests and exams to determine if cancer is present.

📗 These tests may include:

Imaging tests:

Images of the chest or abdomen, such as x-rays, CT scans, or PET scans, can reveal any abnormalities or masses in the body.


A tissue sample from the affected area is taken, and examined under a microscope to determine if cancer cells are present.

Blood tests:

While there is no specific blood test that can diagnose mesothelioma, certain biomarkers may be present in the blood of individuals with the disease.

How is Mesothelioma Treated?

Treatment options for mesothelioma depend on the stage of the cancer, as well as the location and size of the tumor. In some cases, a combination of treatments may be used to provide the best possible outcome.

📗 Mesothelioma treatment options include:


Surgical removal of the tumor and surrounding tissue may be an option in early-stage mesothelioma.


Chemotherapy drugs can be used to kill cancer cells throughout the body.

Radiation therapy:

High-energy radiation can be used to shrink tumors or kill cancer cells.


Immunotherapy drugs can boost the body’s immune system to better target cancer cells.

Mesothelioma FAQs

Q: Are there different types of mesothelioma?

A: Yes, there are three main types of mesothelioma – pleural mesothelioma, peritoneal mesothelioma, and pericardial mesothelioma.

Q: How long does it take for mesothelioma to develop?

A: Mesothelioma can take several decades to develop after exposure to asbestos, with symptoms typically appearing 20-50 years after exposure.

Q: Can mesothelioma be cured?

A: While there is no cure for mesothelioma, treatment options are available that can help manage symptoms and improve quality of life.

Q: Who is at risk for developing mesothelioma?

A: Individuals who were exposed to asbestos in their workplace or through older building materials are at the highest risk for developing mesothelioma.

Q: Can mesothelioma be detected through a routine physical exam?

A: No, mesothelioma is typically not detected through a routine physical exam. Imaging tests and biopsies are typically needed for diagnosis.

Q: How is mesothelioma staged?

A: Mesothelioma is staged based on the size and location of the tumor, as well as the extent of its spread to other areas of the body.

Q: What should I do if I have been exposed to asbestos?

A: If you suspect you have been exposed to asbestos, it is important to speak with a medical professional right away. Regular checkups and monitoring can help detect mesothelioma early if it develops.

Conclusion: Seek Help and Support

📗 Mesothelioma is a devastating disease that impacts thousands of individuals each year. If you or a loved one have been diagnosed with mesothelioma, seeking treatment and support is crucial to managing the condition and maintaining quality of life.

Remember, there are resources available to help individuals with mesothelioma and their families, including support groups, medical professionals, and legal aid. Don’t hesitate to reach out for help and guidance.
