Benign Mesothelioma: Understanding its Causes, Symptoms, Diagnosis, and Treatment :

Hello and welcome to this journal article on benign mesothelioma. This rare form of mesothelioma affects thousands of people every year, and it is important to understand its causes, symptoms, diagnosis, and treatment options. In this comprehensive guide, we will explore everything you need to know about benign mesothelioma, including its definition, types, risk factors, and much more. So, let’s dive right in.

What is Benign Mesothelioma?

As the name suggests, benign mesothelioma is a non-cancerous tumor that develops in the mesothelium, a thin layer of specialized cells that covers the internal organs of the body. Unlike malignant mesothelioma, which is a type of cancer that can spread to other parts of the body, benign mesothelioma is a localized tumor that does not invade nearby tissues or organs.

Benign mesothelioma is a rare disease, accounting for less than 10% of all mesothelioma cases. It is most commonly found in the pleura (the lining of the lungs) and peritoneum (the lining of the abdominal cavity), but it can also occur in the pericardium (the lining of the heart) and tunica vaginalis (the lining of the testicles).

Types of Benign Mesothelioma

There are several different types of benign mesothelioma, each of which can affect different parts of the body. Let’s take a closer look at some of the most common types:

Type of Benign Mesothelioma Affected Area
Benign Pleural Mesothelioma Pleura, the lining of the lungs
Benign Peritoneal Mesothelioma Peritoneum, the lining of the abdominal cavity
Benign Pericardial Mesothelioma Pericardium, the lining of the heart
Benign Tunica Vaginalis Mesothelioma Tunica vaginalis, the lining of the testicles

Causes and Risk Factors

While the exact cause of benign mesothelioma is unknown, it is believed to be linked to exposure to asbestos. Asbestos is a naturally occurring mineral that was widely used in insulation, building materials, and other products throughout the 20th century. When asbestos fibers are inhaled or ingested, they can become trapped in the mesothelium, where they can cause irritation and inflammation over time, leading to the development of mesothelioma.

Other risk factors for benign mesothelioma include:

  • Age: Benign mesothelioma is more common in older adults, particularly those over the age of 60.
  • Gender: Men are more likely than women to develop mesothelioma.
  • Genetics: Some people may be genetically predisposed to developing mesothelioma.
  • Occupational Exposure: People who work in industries that involve exposure to asbestos, such as construction, shipbuilding, and mining, are at a higher risk of developing mesothelioma.

Symptoms of Benign Mesothelioma

The symptoms of benign mesothelioma can vary depending on the type and location of the tumor. In many cases, the tumor may be asymptomatic, meaning that it does not produce any noticeable symptoms. However, in some cases, the tumor can cause a variety of symptoms, including:

  • Chest pain or discomfort (in the case of benign pleural mesothelioma)
  • Abdominal pain or discomfort (in the case of benign peritoneal mesothelioma)
  • Shortness of breath
  • Fever
  • Fatigue or weakness
  • Swelling or lumps in the affected area

Diagnosis of Benign Mesothelioma

If you are experiencing any of the symptoms listed above, it is important to see a doctor as soon as possible. Your doctor may perform a variety of tests to diagnose benign mesothelioma, including:

  • Imaging tests, such as X-rays, CT scans, or MRIs, to visualize the tumor.
  • Tissue biopsy, in which a small sample of the tumor is removed for analysis in a laboratory.
  • Blood tests, which can help identify certain markers associated with mesothelioma.

Treatment of Benign Mesothelioma

The treatment options for benign mesothelioma depend on the location and size of the tumor, as well as the overall health of the patient. In many cases, benign mesothelioma may not require any treatment unless it is causing symptoms, in which case the following treatments may be considered:

  • Surgery, which involves removing the tumor and a small amount of surrounding tissue to ensure that all cancer cells have been eliminated.
  • Radiation therapy, which uses high-energy radiation to kill cancer cells or shrink tumors.
  • Chemotherapy, which involves using drugs to kill cancer cells.
  • Observation, in which the patient is monitored regularly to ensure that the tumor is not growing or causing any further symptoms.


1. Is benign mesothelioma a type of cancer?

No, benign mesothelioma is not a type of cancer. It is a non-cancerous tumor that develops in the mesothelium.

2. Can benign mesothelioma become malignant?

While benign mesothelioma is not cancerous, there is a small risk that it may become malignant over time.

3. What is the prognosis for benign mesothelioma?

The prognosis for benign mesothelioma is generally good, as the tumor is non-cancerous and does not usually require aggressive treatment. However, it is important to monitor the tumor for any changes or growth over time.

4. Can asbestos exposure cause benign mesothelioma?

Yes, asbestos exposure is believed to be a major risk factor for benign mesothelioma.

5. Is surgery necessary to treat benign mesothelioma?

In some cases, surgery may be necessary to remove the tumor and prevent it from causing further symptoms. However, benign mesothelioma may not require any treatment unless it is causing symptoms.


In conclusion, benign mesothelioma is a rare but important disease that can affect the mesothelium in various parts of the body. While it is not cancerous, it can cause a variety of symptoms and may require treatment in some cases. If you are experiencing any of the symptoms associated with benign mesothelioma, it is important to see a doctor as soon as possible to receive an accurate diagnosis and appropriate treatment.
