Mesothelioma is an uncommon and aggressive cancer that develops in the thin lining around certain organs. The overwhelming majority of cases are linked to past exposure to asbestos, often decades earlier, in settings such as shipyards, construction, manufacturing, power plants, and military service. Because it is rare, many doctors see few cases, and the choices patients face can feel overwhelming. This guide summarizes mesothelioma treatment options, how to find experienced care, and the financial resources available. It is educational information, not medical advice; treatment decisions should be made with your oncology team.
Types of mesothelioma
- Pleural mesothelioma affects the lining of the lungs and is the most common form.
- Peritoneal mesothelioma affects the lining of the abdomen.
- Pericardial mesothelioma affects the lining around the heart and is very rare.
- Testicular mesothelioma, in the tunica vaginalis, is extremely rare.
Pathologists also classify tumors by cell type. Epithelioid mesothelioma is the most common and generally responds better to treatment. Sarcomatoid is less common and more aggressive. Biphasic tumors contain both cell types. Cell type strongly influences treatment recommendations.
Diagnosis
Symptoms of pleural mesothelioma can include shortness of breath, chest pain, persistent cough, and fluid around the lungs, called pleural effusion. Peritoneal disease may cause abdominal swelling, pain, and fluid. Because symptoms resemble more common conditions, diagnosis can be delayed.
Diagnosis typically involves imaging such as CT or PET scans, removal and analysis of fluid, and a tissue biopsy, often obtained through thoracoscopy or laparoscopy. Pathologists use immunohistochemical staining to distinguish mesothelioma from other cancers. Given the rarity, a second pathology opinion from an experienced center is often worthwhile.
Treatment approaches
Treatment depends on the type, cell type, stage, and the patient’s overall health. Care is usually multidisciplinary, involving thoracic or surgical oncologists, medical oncologists, radiation oncologists, and palliative care specialists.
Systemic therapy
Immunotherapy. In 2020, the FDA approved the combination of nivolumab and ipilimumab, two immune checkpoint inhibitors, as a first-line treatment for unresectable malignant pleural mesothelioma, based on a clinical trial that showed improved overall survival compared with chemotherapy, with particular benefit in non-epithelioid tumors. In 2024, the FDA approved pembrolizumab in combination with chemotherapy for first-line treatment of unresectable advanced or metastatic pleural mesothelioma.
Chemotherapy. The combination of pemetrexed and a platinum drug, such as cisplatin or carboplatin, has long been a standard first-line chemotherapy for pleural mesothelioma. Some regimens add bevacizumab for eligible patients. Chemotherapy may also be used before or after surgery.
Surgery
For selected patients with early-stage disease and good overall health, surgery may be part of treatment. Approaches for pleural mesothelioma include pleurectomy/decortication, which removes the pleura and visible tumor while sparing the lung, and extrapleural pneumonectomy, which removes the lung and surrounding structures. Many centers have moved toward lung-sparing approaches in recent years. Surgical candidacy is a nuanced decision, and experts differ on its role, so evaluation at a high-volume center is important.
For peritoneal mesothelioma, cytoreductive surgery combined with heated intraperitoneal chemotherapy (HIPEC) is used at specialized centers for selected patients.
Radiation therapy
Radiation may be used after surgery, to relieve pain, or to treat specific areas. Advanced techniques such as intensity-modulated radiation therapy allow more precise targeting.
Palliative and supportive care
Palliative care focuses on relieving symptoms and improving quality of life at every stage, not just at the end of life. Procedures such as draining fluid, placing an indwelling pleural catheter, or pleurodesis can relieve breathlessness. Pain management, nutrition support, and emotional support are part of comprehensive care.
Clinical trials
Because mesothelioma is rare and outcomes remain difficult, clinical trials are an important option. Trials test new immunotherapy combinations, targeted therapies, cell therapies, and surgical strategies. You can search ClinicalTrials.gov or ask the National Cancer Institute’s Cancer Information Service for help. Many trials cover the cost of the investigational treatment, and federal law requires most health plans to cover routine patient care costs in approved clinical trials.
Finding experienced specialists
Research suggests that outcomes for rare cancers can be better at centers that treat a high volume of cases. National Cancer Institute-designated cancer centers and major academic medical centers often have dedicated mesothelioma or thoracic oncology programs. Ask any prospective team how many mesothelioma patients they treat each year, whether they hold multidisciplinary tumor boards, and what clinical trials they offer. Patient organizations, such as the Mesothelioma Applied Research Foundation, maintain information on treatment centers.
Paying for treatment
Mesothelioma treatment can be very expensive, especially with immunotherapy, surgery, and long-term follow-up.
Health insurance and Medicare
Medicare covers cancer treatment, including chemotherapy and immunotherapy given in a clinic (usually under Part B) and oral cancer drugs (under Part D, which now has an annual out-of-pocket cap). Private plans cover treatment subject to deductibles, coinsurance, and out-of-pocket limits, and often require prior authorization for expensive drugs. Confirm that your cancer center is in network, or ask about single case agreements if the only qualified specialist is out of network.
Veterans benefits
Many people with mesothelioma were exposed to asbestos during military service, particularly in the Navy. Veterans with service-connected mesothelioma may qualify for VA disability compensation, which is often rated at 100 percent while the disease is active, as well as VA health care. The VA operates specialized cancer programs, and veterans may be able to receive care in the community through VA programs. Surviving spouses may qualify for Dependency and Indemnity Compensation. Accredited veterans service officers can help file claims at no cost.
Asbestos bankruptcy trust funds
Many companies that made or used asbestos products filed for bankruptcy and established trusts to pay current and future claimants. Billions of dollars have been set aside in these trusts. Claims typically require proof of diagnosis and evidence of exposure to that company’s products. Trust payments are often a percentage of the scheduled value, and filing deadlines apply. People often pursue trust claims alongside lawsuits with the help of an attorney experienced in asbestos litigation.
Legal claims
Patients and families may be able to bring personal injury or wrongful death lawsuits against companies whose asbestos products caused the illness. Statutes of limitations, which are often measured from the date of diagnosis, vary by state, so it is important to consult an attorney promptly. Most asbestos attorneys work on contingency, meaning they take a percentage of any recovery rather than charging upfront fees.
Other financial help
Social Security Disability Insurance includes mesothelioma under its Compassionate Allowances program, which speeds disability decisions. Hospital social workers and financial counselors can help with charity care, drug manufacturer assistance programs, and travel and lodging assistance for treatment at distant centers.
Questions to ask your care team
- What type and cell type is my mesothelioma, and what stage?
- Am I a candidate for surgery? Why or why not?
- What first-line systemic therapy do you recommend, and what are the expected side effects?
- Are there clinical trials I qualify for?
- How will we manage symptoms such as breathlessness and pain?
- Who can help me understand costs and coverage?
Living with mesothelioma day to day
Beyond medical treatment, patients often benefit from practical support. Pulmonary rehabilitation programs can help people with breathlessness build stamina, and many are covered by Medicare and private insurance when criteria are met. Dietitians can help maintain weight during chemotherapy or immunotherapy. Counselors and support groups, including online groups for mesothelioma patients and caregivers, help families cope with a rare diagnosis that friends may not understand. Caregivers should ask about respite services and the Family and Medical Leave Act, which may protect their jobs while they provide care. Advance care planning, including naming a health care proxy and documenting treatment preferences, ensures that the patient’s wishes guide decisions if they become unable to speak for themselves.
Keeping records
Keep copies of pathology reports, imaging, treatment summaries, and a written history of where and when asbestos exposure may have occurred, including employers, job sites, ships, and products used. These records support second opinions, VA claims, trust fund claims, and legal actions.
