The Board denied service connection for thyroid cancer as the evidence did not support a causal or etiological relationship to active service, including exposure to radiation and/or herbicides.
The deciding factor: The evidence of record does not support a finding that the Veteran's thyroid cancer is causally related to his active service, and there was no reasonable possibility that it resulted from ionizing radiation exposure during military service.
