Mesothelioma What To Know About It

Mesothelioma What To Know About It

A Mesothelioma is a serious illness caused by exposure to asbestos. It most often forms in the thin lining around the lungs or abdomen. Although it is not common, mesothelioma is known for being aggressive and difficult to detect in its early stages. Symptoms usually take many years to appear after exposure. These symptoms can include chest pain, shortness of breath, fatigue, and unexplained weight loss.

Many individuals who are diagnosed with mesothelioma were exposed to asbestos through work or by coming into contact with older building materials. Asbestos is no longer mined in the United States, but it is still present in some homes, schools, and commercial buildings. This is why awareness and prevention remain important.

On average, people diagnosed with mesothelioma live between 18 and 31 months. However, outcomes can vary based on when the cancer is found and how well it responds to treatment. Common treatment options include surgery and chemotherapy. Newer approaches, such as immunotherapy, may also help improve survival and quality of life. A team of specialists can help create a treatment plan that fits the patient’s specific condition.

Whether you are learning about mesothelioma for yourself or for someone you care about, understanding the basics is an important first step. In this guide, we will explain what causes mesothelioma, the different types, the warning signs to watch for, how doctors diagnose it, and the treatments available today.

What is Mesothelioma?

Mesothelioma is a type of cancer that begins in the mesothelium, a thin layer of tissue that surrounds many internal organs. It most often develops in the lining around the lungs, which is known as pleural mesothelioma. However, it can also form in the lining of the abdomen, the heart, or even the testicles.

Sometimes referred to as malignant mesothelioma, this cancer tends to grow quickly and can be very serious. While there are treatment options available, mesothelioma is often difficult to cure, especially when it is diagnosed in later stages.

What Causes Mesothelioma?

Most cases of mesothelioma are caused by exposure to asbestos. Asbestos is a group of minerals found naturally in rocks and soil. These minerals form long, thin fibres that are incredibly strong and resistant to heat, fire, and chemicals. They do not break down easily in the body or the environment.

Because of these qualities, asbestos was widely used throughout the 20th century in many products, including building materials, car parts, and household items. At the time, people did not realise how dangerous it could be. While asbestos is no longer mined in the United States, it is still imported for use in some products and can still be found in older buildings and homes.

When materials that contain asbestos are disturbed, whether during construction, repairs, or demolition, tiny fibres can be released into the air. These fibres are too small to see, but they can be inhaled or swallowed. Over time, this exposure can lead to mesothelioma and other serious health problems.

Not everyone who is exposed to asbestos will develop mesothelioma, but long-term exposure increases the risk. If you have worked around asbestos or think you may have been exposed, it is a good idea to talk with your doctor about regular checkups or tests for asbestos-related diseases.

How Asbestos Exposure Leads to Mesothelioma| Mesothelioma What To Know About It

When someone breathes in or swallows asbestos fibres, the tiny particles can travel deep into the body and settle in the lining of the lungs, abdomen, or heart. These linings, called the mesothelium, become irritated and inflamed over time.

This ongoing irritation can cause scar tissue to build up, which may eventually turn into cancer. Mesothelioma tumours often begin to form in this scar tissue, but it can take 20 to 50 years after the initial asbestos exposure for the disease to develop. The type of mesothelioma someone gets often depends on how they were exposed to asbestos:

Pleural mesothelioma is the most common type and starts when asbestos fibres are inhaled and lodge in the lining of the lungs. Over time, they cause inflammation and scarring, which can lead to cancer.
Peritoneal mesothelioma develops when asbestos fibers are swallowed and settle in the lining of the abdomen.
Pericardial mesothelioma, which affects the lining around the heart, is rare. In many cases, it may begin as pleural mesothelioma that spreads to the pericardium.

Types of Mesothelioma| Mesothelioma What To Know About It

The most common type of mesothelioma is pleural mesothelioma, which affects the lining of the lungs. Other types include:

Peritoneal mesothelioma: This type affects the lining of the abdominal and pelvic cavities and is the second most common form of mesothelioma.
Pericardial mesothelioma: This rare type impacts the sac around the heart.
Mesothelioma of the tunica vaginalis testis (paratesticular mesothelioma): Also very rare, this type affects the lining around the testicles.

Symptoms Of Mesothelioma

The symptoms of mesothelioma can vary depending on where the cancer develops.

Pleural mesothelioma, which affects the lining around the lungs, may cause:

Chest pain
Painful coughing
Shortness of breath
Lumps under the skin on the chest
Fatigue
Unexplained weight loss

Peritoneal mesothelioma, which develops in the lining of the abdomen, may lead to:

Abdominal pain
Swelling in the belly
Nausea
Fatigue
Unexplained weight loss

Other types of mesothelioma are much less common, and fewer details are known about them.

Pericardial mesothelioma, which affects the lining around the heart, may cause:

chest pain
difficulty breathing.

Mesothelioma of the tunica vaginalis, which involves the lining around the testicles, may first show up as

swelling or a lump on a testicle.

If you notice any of these symptoms and have a history of asbestos exposure, it is important to speak with a doctor as soon as possible.

What Increases the Risk of Mesothelioma?

The main risk factor for mesothelioma is asbestos exposure. Most people who develop this cancer were exposed to asbestos at some point in their lives. However, there are a few other, less common factors that can raise the risk, too. Having one or more risk factors does not mean you will get mesothelioma, it just means your chances may be higher.
Below are some of the key risk factors:

Direct asbestos exposure: This happens when someone works with or around asbestos and breathes in the tiny fibres. It is the leading cause of mesothelioma, with about 80 per cent of cases linked to this type of exposure.
Secondhand exposure: People who live with someone who works with asbestos can also be at risk. Fibres can come home on clothes, skin, or hair, and others in the household may breathe them in over time.
Radiation treatment: Some studies suggest that people who received radiation therapy for other cancers may have a slightly higher chance of developing mesothelioma later in life.
Genetics: In rare cases, inherited gene changes, like the BAP1 mutation, can raise the risk of mesothelioma. People with this mutation may be more likely to develop the disease, even with only low-level asbestos exposure or no known exposure at all.

Diagnosing Mesothelioma| Mesothelioma What To Know About It

Early diagnosis is important when it comes to malignant mesothelioma. While symptoms can raise concerns, the only way to confirm a diagnosis is through a biopsy. This involves taking a small sample of tissue so doctors can check for cancer cells under a microscope.

If you know or suspect that you have been exposed to asbestos, it is important to let your doctor know. This information can help them watch for early warning signs of asbestos-related diseases. If symptoms do appear, seeing a specialist with experience in diagnosing mesothelioma can make a big difference in getting the right tests and care.

How to Help Prevent Mesothelioma

There is no safe level of asbestos exposure. Even small amounts can increase your risk of developing mesothelioma. That is why the best way to prevent this disease is to avoid contact with asbestos as much as possible. If you work in an environment where asbestos might be present, always wear protective gear and follow all safety guidelines for handling it. These steps can help reduce your risk.

If you think your home might have asbestos, especially in older insulation, tiles, or roofing, it is best to call a trained asbestos professional. Asbestos is not always dangerous if it is left undisturbed, so it does not need to be removed just because it is there. The problem happens when the material gets damaged and releases fibres into the air. If you are planning renovations or repairs that could disturb asbestos-containing materials, it is important to hire a certified expert. They know how to safely remove asbestos without putting you or your family at risk.

Mesothelioma Treatment Options

Treating mesothelioma is crucial for improving a patient’s prognosis, including enhancing quality of life and possibly extending life expectancy. The main treatments for mesothelioma include chemotherapy and surgery, with immunotherapy being a newer approach that has recently become more common.

Often, doctors will use a combination of treatments, known as multimodal treatment, to give patients the best chance for survival. This combined approach has led to some of the most successful outcomes for mesothelioma patients.

Chemotherapy:

Chemotherapy works by using drugs to kill cancer cells and prevent them from growing. The typical first-line chemotherapy for mesothelioma is a combination of cisplatin or carboplatin with Alimta® (pemetrexed). It’s often used along with other treatment methods.

Immunotherapy:

Immunotherapy helps the immune system recognise and fight cancer cells. It has been particularly effective for patients with more complex or advanced cases. A combination of Opdivo® (nivolumab) and Yervoy® (ipilimumab) is FDA-approved for pleural mesothelioma cases.

Multimodal treatment:

This approach combines two or more treatments to target the cancer from different angles. For example, combining surgery with chemotherapy is a common multimodal strategy to remove and destroy cancer cells.

Surgery:

Surgery involves physically removing the cancerous tissue. It can be used at different stages of the disease, though in later stages, surgery is often more about easing symptoms and improving comfort, rather than trying to cure the cancer.

How Do You Know if You Have Mesothelioma?

If you have a history of asbestos exposure, it’s important to share this information with your doctor. Be sure to mention any ongoing symptoms you may have, such as chest pain, a persistent cough, or difficulty breathing.
One thing to keep in mind is that mesothelioma has a long latency period. It can take anywhere from 20 to 60 years after exposure for symptoms to develop, so they may not appear until many years later.

Is There a Cure for Mesothelioma?

Currently, mesothelioma does not have a cure. However, researchers are working hard to develop new treatments through clinical trials. Some patients live longer than expected, and a small number have survived more than a decade after their diagnosis. New treatments like immunotherapy offer hope for improving survival and, potentially, finding a cure in the future.

How Doctors Diagnose Mesothelioma| Mesothelioma What To Know About It

To diagnose mesothelioma, your doctor will consider your symptoms and medical history and may recommend several tests to confirm or rule out the condition:

Blood tests: These can help check for specific markers related to mesothelioma.
Lung function tests: These tests assess how well your lungs are working, which can be affected by mesothelioma.
Imaging tests: Chest X-rays and CT scans are commonly used to look for signs of mesothelioma and to check for tumours.
PET scans: These scans help doctors see if the cancer has spread to other parts of the body.
Fluid drainage: If there’s fluid buildup in the chest or abdomen, your doctor may perform a procedure called thoracentesis (for the chest) or paracentesis (for the abdomen) to drain the fluid and check for cancer cells.
Biopsy: A biopsy involves taking a small sample of tissue to be examined under a microscope to confirm the presence of cancer.

Mesothelioma is a serious disease that is closely linked to asbestos exposure. Learning about the symptoms, knowing the risks, and getting medical help early can help.
