PORTSMOUTH, VA — When Thomas Greer's VA claim for mesothelioma was denied the first time, his daughter assumed it was a paperwork problem. When it was denied a second time, she started making phone calls.
Greer, a 71-year-old retired Navy machinist who spent 24 years servicing engine rooms aboard vessels where asbestos insulation wrapped every pipe and bulkhead, had been diagnosed with pleural mesothelioma in late 2024. His family submitted what they believed was a complete disability claim. The VA disagreed, twice, citing insufficient documentation of service-connected asbestos exposure. It took two years, a patient advocate, and a formal appeal before his claim was finally approved in early 2026.
His case is not unusual. It is, advocates say, the norm.
The Documentation Gap That Defeats Veteran Claims
What happened to Greer reflects a pattern that recurs across VA regional offices: veterans with mesothelioma, one of the most clearly asbestos-linked cancers in medical literature, are still being asked to prove individual exposure events that occurred decades ago aboard ships where asbestos use was standard and pervasive.
According to the National Cancer Institute's SEER database, mesothelioma carries a median survival of roughly 12 to 21 months from diagnosis, meaning the administrative timeline for a contested claim can consume a significant portion of a patient's remaining life. The disease is almost exclusively caused by asbestos exposure, according to the World Health Organization, making occupational naval service one of the most recognized risk pathways.
The VA does recognize mesothelioma as a service-connected condition for veterans who can demonstrate asbestos exposure during service. But "demonstrate" is where the system breaks down. Service records from the 1970s and 1980s rarely document which specific materials a machinist handled on which ship. Asbestos was simply everywhere, and no one thought to write it down.
"What I hear from patients going through this is that they feel like they're being asked to prove something everyone already knows," said Yvette Abrego, patient advocate at Mesothelioma-Lung-Cancer.org. "These men worked in the engine rooms. The pipes were wrapped in asbestos. That's not a secret. But the VA process treats it like a mystery that needs solving."
Why the Stakes Are Higher Than Most Families Realize
For veterans like Greer, an approved VA claim unlocks more than monthly disability compensation. It can open access to VA healthcare, including oncology services at facilities affiliated with major academic medical centers. It can also establish a legal foundation for additional claims against asbestos trust funds, which have paid out more than $20 billion since the first funds were established.
The distinction matters because many veterans don't realize that VA benefits and civil compensation are not mutually exclusive. A veteran whose mesothelioma is service-connected can simultaneously pursue claims through the asbestos bankruptcy trust fund system, which holds billions in assets set aside specifically for asbestos victims. The two tracks operate independently, and pursuing one does not disqualify a patient from the other.
For families navigating both systems at once, the cognitive and logistical burden is enormous. Greer's daughter described spending evenings after hospital visits sorting through discharge papers, ship manifests, and medical records, trying to build the paper trail the VA required.
Understanding the full scope of asbestos exposure risks and compensation pathways is something many families don't encounter until they're already deep into the process, often after critical deadlines have passed.
What Patients and Families Can Do Right Now
The most important step you can take right now, if you or a veteran in your family has been diagnosed with mesothelioma, is to begin documenting service history immediately, before memory fades and before records become harder to retrieve.
That means requesting military service records through the National Personnel Records Center, identifying the specific ships or bases where service occurred, and cross-referencing those locations with known asbestos use. Veterans' service organizations, including the DAV and VFW, offer free claims assistance that can help families structure the documentation the VA requires.
Beyond the VA, families should also explore whether the diagnosing physician can provide a nexus letter, a medical opinion connecting the mesothelioma diagnosis to asbestos exposure. This document is often the single most powerful piece of evidence in a contested claim, and many VA denials happen precisely because no nexus letter was submitted with the initial filing.
Many patients and families I've worked with have found that a second opinion on both the medical diagnosis and the legal claim strategy changes the trajectory of their case entirely. Mesothelioma specialists at major academic centers are often willing to provide the kind of detailed documentation that general oncologists don't know to include. Our guide to choosing a mesothelioma treatment center walks through what to look for when selecting a facility that understands both the clinical and documentation needs of veterans.
For Greer, the approval came in time to help his family stabilize financially during his treatment. His daughter said she wishes they'd known in the first month what they only learned after two years of fighting. That knowledge gap, she said, is the real problem.
"He earned this. He earned it the day he enlisted." The VA system, she believes, should make that easier to prove, not harder.
