Types of Mesothelioma

Quick Summary

Mesothelioma is a cancer that starts in the linings of major organs. It has 4 main types. Most people develop mesothelioma in the lining of their lungs (pleural mesothelioma) or abdomen (peritoneal mesothelioma). It can also occur in the heart lining (pericardial mesothelioma) or testicles (testicular mesothelioma). There is no cure for any type of mesothelioma, but medical treatments may help you live longer.

What Are the Types of Mesothelioma?

Mesothelioma tumors grow in the lining of major organs. There are 4 different types of mesothelioma. Which type you have depends on where the cancer started.

Mesothelioma can occur in the lining of your:

  • Lungs
  • Heart
  • Chest
  • Testicles

Though mesothelioma can start in different areas in the body, all types share similarities. For example, they share a common cause: exposure to asbestos fibers. Asbestos is a strong, fibrous mineral once used in many construction and vehicle products.

If these products were damaged, microscopic asbestos fibers would enter the nearby air. Those who inhaled these fibers were in grave danger. Once inside the body, asbestos fibers get lodged into nearby tissue.

The fibers cannot naturally be broken down by the body. Over time, they cause damage at a cellular level. This damage can eventually lead to mesothelioma after 20-50 years.

To diagnose mesothelioma, doctors will scan the affected area for signs of cancer. They will then take a biopsy (tissue sample) to look for cancerous cells.

What is My Mesothelioma Outlook?

There is no cure for any type of mesothelioma. There are treatments available for each type that can extend a patient’s lifespan. However, the effectiveness of treatments depends on each person’s unique case.

Filing a claim with a mesothelioma law firm can help you afford the high cost of treatment. When you file a claim, the law firm will work on your behalf to get you financial compensation.

Claims are usually brought against the makers of asbestos products who knew the health risks of their products but sold them to make billions.

Mesothelioma by Type

Because mesothelioma can develop in different parts of your body — often with only vague symptoms — you should learn the basics about each type.

Consult your doctor if you are feeling any of the symptoms mentioned below. Make sure to discuss your history of asbestos exposure. This can help them narrow down the cause of your illness and lower the risk of a misdiagnosis.

Pleural Mesothelioma

Pleural mesothelioma is by far the most common type. It accounts for 75% of all mesothelioma cases. Pleural mesothelioma develops in the lining of the lungs (also known as the pleura). The pleura helps reduce friction as the lungs work. There are two layers in the pleura with fluid in between them.

When asbestos fibers get lodged in the pleura, they cause serious damage and scarring. This makes it harder for the pleura to do its job over time. The pleura may become thick, and the fluid may build up and leak into the lungs.

However, pleural mesothelioma often begins with mild and vague symptoms. As a result, it can easily be mistaken for many other illnesses.

Early symptoms include:

  • Chest pain
  • Coughing
  • Difficulty breathing

As the cancer worsens, serious symptoms include:

  • Coughing up blood
  • Nausea
  • Fevers

To treat pleural mesothelioma, doctors will first determine if the disease has spread. If the disease is contained to just the pleura, they will remove the diseased portions. They will also remove parts of other organs, such as a lung, as a precaution in some cases.

Peritoneal Mesothelioma

Peritoneal mesothelioma is the second most common type. This type makes up around 20% of all mesothelioma cases. Peritoneal mesothelioma starts in the lining of the chest (the peritoneum).

The peritoneum is a protective layer of tissue that covers the lining of major organs, including the stomach, large intestine, and small intestine. Early symptoms may include abdominal swelling, pain, and loss of appetite. Like symptoms for other mesothelioma types, these start out mild and only worsen.

Symptoms of peritoneal mesothelioma include:

  • High fever
  • Nausea and vomiting
  • Seizures

Pleural mesothelioma responds better to treatments compared to the other types. Most often, mesothelioma surgeons will perform cytoreduction with HIPEC. This procedure removes cancerous tumors from the affected area and then bathes the surgery site in cancer-killing drugs.

However, cytoreduction with HIPEC may not be an option if the cancer has spread. In these cases, less intense treatment methods will be used to manage painful symptoms.

Pericardial Mesothelioma

Pericardial mesothelioma is a rare form of the disease. About 200 cases have been reported in total. Pericardial mesothelioma develops in the lining of the heart (the pericardium).

Because this type of mesothelioma is so rare, scientists are still determining its exact causes and symptoms. The most important symptoms are inflammation and fluid buildup in the pericardium from cancerous tumors.

Other notable symptoms include:

  • Chest pain
  • Fever
  • Irregular heartbeat
  • Persistent cough

Pericardial mesothelioma, if caught early enough, can be treated with a pericardiectomy. This removes the diseased part of the pericardium where most of the cancer is. However, if the cancer has spread, this will not be an option because it could put the patient’s life at risk.

Pericardial mesothelioma has a very poor life expectancy. Most patients require palliative care, as they are diagnosed with the disease after it has spread.

Testicular Mesothelioma

Testicular mesothelioma is the rarest type. Between the late 1950s and 2012, there were only 100 reported cases of testicular mesothelioma.

Testicular mesothelioma develops in the lining of the testicles known as the tunica vaginalis. Over time, cancerous masses may develop on the testicles themselves.

Much like pericardial mesothelioma, little is known about how this type develops or all of its symptoms.

Reported symptoms include:

  • Fluid buildup in the scrotum
  • Thickening of tunica vaginalis
  • Swelling of the testicles

In nearly all cases, the cancer starts out in one testicle before spreading throughout the body. To treat testicular mesothelioma, doctors will typically remove the affected testicle. Chemotherapy may also be used if the cancer has spread, though its effects are limited.

Testicular mesothelioma has decent survival odds if caught early on. Recent data suggests that the median survival rate for patients is 2 years. Some patients may live longer than 5 years after their first diagnosis in rare cases.

Help for Each Type of Mesothelioma

If you or someone you love may be suffering from mesothelioma, it is important to seek medical care from a mesothelioma specialist. They will be able to make a proper diagnosis and recommend the next steps for treatment.

Be sure to take extra notice if you or a loved one meet these criteria:

  • Has a history of asbestos exposure
  • Has persistent, yet vague, symptoms
  • Is over the age of 40

Following a mesothelioma diagnosis, you may consider filing a claim with a mesothelioma law firm. Most cases of mesothelioma could have been prevented had companies not made products with asbestos.

For decades, these manufacturers knew the health risks that asbestos posed. However, they continued to use asbestos to make a profit, even when they realized it could lead to cancer.

A mesothelioma legal claim helps you earn monetary compensation from these companies. This payout can help pay for costs associated with your medical care and provide financial security for your family.
