In claims like these, a surviving spouse pursues a cause-of-death claim for a Vietnam veteran whose aggressive cancer was denied a service connection. An Independent Medical Opinion connects the cancer to a service-connected metabolic condition and shows how other service-connected disabilities aggravated its course by making a recommended treatment physically impossible, applying the but-for standard from Spicer v. McDonough.
The Challenge
When the veteran has passed, the entire case must be built from existing records. Two problems commonly stand in the way. The cancer at issue is not an Agent Orange presumptive, so there is no shortcut through conceded herbicide exposure. And a prior VA reviewer often dismisses the link between a service-connected condition and the cancer as an association rather than proof of causation.
What Existed Before
- A DD-214 confirming Vietnam service and conceded Agent Orange exposure.
- A death certificate identifying the cancer as the immediate cause of death.
- Civilian and VA treatment records, including the treating physician's notes.
- A prior VA denial citing association rather than causation.
- Lay testimony from the surviving spouse.
- No medical opinion tying the cancer to service.
Our Contribution
- Reviewed the full medical and service record together with the lay testimony.
- Established a long-standing service-connected metabolic condition as a recognized risk factor for the cancer, grounded in peer-reviewed literature.
- Anchored the argument to a condition that predated the cancer by years, separating it from a condition that appears only after a tumor develops.
- Built the aggravation argument that service-connected orthopedic and psychiatric conditions made a recommended treatment physically impossible to tolerate.
- Tied that barrier to the treating physician's own documentation.
- Applied the but-for and inability-to-treat standard from Spicer v. McDonough.
- Answered the prior denial directly with individualized mechanisms and the veteran's own documented findings.
Key Takeaway
- A cancer that is not an Agent Orange presumptive can still be connected through a service-connected condition acting as an intermediate cause.
- Aggravation now reaches situations where a service-connected disability blocks or delays treatment of another condition, under Spicer v. McDonough.
- The objection that association is not causation is answered with individualized evidence, not more statistics.
- A strong Independent Medical Opinion engages the prior denial head-on rather than restating the claim.
