Why should Veterans have to prove what the VA already knows

Requiring the Veteran to prove exposures based on what is in the medical record is criminal and is the single source for the benefit backlogs. This is the MAJOR problem with the VA, why should we have to prove a chemical exposure the VA already KNOWS we suffered.

No corpsman or medic documented in our medical records the exposures to all of the chemicals such as Asbestos, Carbon Tet, TCE, Agent Orange, burn pits, etc. The Theater of Operations, MOS or NEC should be the primary factors to determine a Veteran medical or disability claim, NOT the medical records!  Medical records should only be used as supplemental secondary supportive documentation. Even when a medical jacket cover had the word ASBESTOS in red, the VA does NOT monitor the Veteran because there is no ASBESTOS registry.Veteran Medical Records 01
