Mesothelioma is a rare, aggressive cancer that develops in the lining of certain internal organs. It is caused by exposure to asbestos—a hazardous mineral used widely in construction, shipbuilding, and manufacturing throughout the 20th century.
This type of cancer most commonly forms in the chest or abdominal cavity, and it often goes undiagnosed until it has reached an advanced stage. Understanding what mesothelioma is—and how it’s linked to asbestos exposure—is a critical first step toward protecting your health and your legal rights.
How Mesothelioma Develops
Mesothelioma begins when microscopic asbestos fibers are inhaled or swallowed. These fibers lodge in the body’s mesothelium—the protective tissue lining the lungs, abdomen, and heart—where they can remain for decades.
Over time, the body’s inflammatory response to the fibers may lead to cellular damage, scarring, and genetic mutations. This can eventually trigger cancer in the affected area.
Among the different forms of the disease, pleural mesothelioma is the most common. It develops in the pleura, the tissue lining the lungs. Other forms include peritoneal mesothelioma, which affects the abdominal lining, and the rarer pericardial mesothelioma, which forms around the heart.
Asbestos Exposure: The Only Known Cause
The only medically established cause of mesothelioma is exposure to asbestos. For decades, workers in industries like shipbuilding, construction, power generation, and automotive repair were exposed to asbestos fibers on the job. In many cases, employers failed to warn them of the danger or provide adequate protective equipment.
Occupational asbestos exposure remains the leading risk factor for mesothelioma. However, secondhand asbestos exposure—when family members inhale fibers brought home on clothing—has also led to many cases.

Why Mesothelioma Can Take Decades to Appear
One of the reasons mesothelioma is so dangerous is its long latency period. Symptoms usually do not appear until 20 to 50 years after exposure. By that time, the disease may already be in an advanced stage.
This delay often makes it difficult for patients to identify the source of their exposure. Many people do not realize they worked around asbestos—or lived with someone who did—until long after the fact.
If you’re unsure whether you or a loved one may have been exposed, review our guide to asbestos exposure and risk factors.
Recognizing the Early Symptoms
Mesothelioma symptoms depend on where the cancer develops. In pleural mesothelioma, the earliest signs may include shortness of breath, chest pain, and persistent coughing. Peritoneal mesothelioma often causes abdominal pain, bloating, and digestive issues.
Because these symptoms mimic more common conditions, they are frequently misdiagnosed. If you or a loved one has a history of asbestos exposure, visit our page on mesothelioma symptoms to understand what to watch for.
Who is at Risk for Mesothelioma?
People who worked in high-risk industries are the most vulnerable. This includes:
- Shipyard workers and Navy veterans
- Oilfield workers – roughnecks, drillers, roustabouts
- Electricians and pipefitters
- Insulators and construction workers
- Refinery, factory, and power plant employees
- Mechanics exposed to asbestos in brakes and clutches
Even family members of workers can be at risk due to secondhand exposure. If you or someone close to you worked in one of these fields, you may qualify for a mesothelioma legal claim.
Legal Rights for Mesothelioma Victims
Many companies continued to use asbestos long after its dangers were known—putting profits above worker safety. Today, victims of asbestos exposure may be entitled to financial compensation through:
- Personal injury lawsuits
- Wrongful death claims
- Asbestos trust fund claims
- VA benefits for veterans
