The Veteran's cause of death from extensive stage small cell lung cancer was not service-connected due to lack of evidence showing exposure to herbicide agents during his service at U-Tapao Royal Thai Air Force Base.
The deciding factor: The Board found insufficient evidence to establish the Veteran’s exposure to herbicide agents, which is a prerequisite for presumptive service connection under 38 C.F.R. § 3.309(e).
