Mesothelioma Quick Facts

Overview

Mesothelioma is an aggressive cancer of the mesothelial lining caused almost exclusively by asbestos exposure. Approximately 2,500-3,000 new cases are diagnosed annually in the United States.[1] The disease has a median latency period of 20-50 years between first asbestos exposure and diagnosis, with a median age at diagnosis of 72 years.[2] The overall five-year survival rate is approximately 12%, though outcomes vary significantly by type, stage at diagnosis, and treatment approach.[1]

Four Types of Mesothelioma

Type Location Percentage 5-Year Survival
Pleural Mesothelioma Lung lining (pleura) ~75% 10-12%[1]
Peritoneal Mesothelioma Abdominal lining (peritoneum) ~20% 30-65% (with HIPEC)[7]
Pericardial Mesothelioma Heart lining (pericardium) ~1% 6 months median[2]
Testicular Mesothelioma Tunica vaginalis <1% ~50% (limited data)[2]

Frequently Asked Questions

What causes mesothelioma?

Asbestos exposure is the primary cause of mesothelioma, accounting for approximately 80% of all diagnosed cases.[2] When asbestos fibers are inhaled or ingested, they can become lodged in the mesothelial lining where they cause chronic inflammation and DNA damage over decades. Secondhand exposure through contaminated clothing or household dust also causes cases.[8]

How long does mesothelioma take to develop?

The latency period between asbestos exposure and mesothelioma diagnosis ranges from 20 to 50 years, with a median of approximately 30-40 years.[3] This extended latency means many patients diagnosed today were exposed to asbestos in the 1970s-1990s, often in occupational settings.[9]

What is the survival rate for mesothelioma?

The overall five-year survival rate for mesothelioma is approximately 12%.[1] However, survival varies significantly by type: peritoneal mesothelioma treated with surgery and HIPEC (heated chemotherapy) can achieve 5-year survival rates of 30-65%.[7] Early-stage diagnosis and multimodal treatment improve outcomes substantially. See Mesothelioma Survival Rates for detailed statistics.

Who is most at risk for mesothelioma?

The highest-risk groups include workers in construction, shipbuilding, insulation, automotive repair, and industrial manufacturing who handled asbestos-containing materials.[9] Military veterans, particularly Navy personnel, account for approximately 30% of all mesothelioma diagnoses due to heavy asbestos use in ships and military facilities.[10] See the Occupational Exposure Index for a complete list of high-risk occupations.

What are the early symptoms of mesothelioma?

Early mesothelioma symptoms are often subtle and mimic common respiratory conditions. For pleural mesothelioma, early signs include persistent chest pain, shortness of breath, unexplained weight loss, and fatigue.[2] Peritoneal mesothelioma may present with abdominal pain, swelling, and digestive changes. Early detection through regular screening of asbestos-exposed individuals improves treatment options.

What treatment options are available?

Mesothelioma treatment typically involves a multimodal approach combining surgery, chemotherapy, and radiation therapy.[11] Immunotherapy drugs including nivolumab and ipilimumab received FDA approval for unresectable mesothelioma and have shown improved survival.[12] Clinical trials continue to expand available treatment options. See Mesothelioma Treatment Centers for specialized facilities.

Yes. Patients diagnosed with mesothelioma may be eligible for compensation through personal injury lawsuits, asbestos bankruptcy trust fund claims, VA disability benefits (for veterans), and settlements.[13] The statute of limitations varies by state, typically 1-6 years from diagnosis. An experienced mesothelioma attorney can pursue multiple compensation sources simultaneously.
