Investigative Documents
Preliminary questions [22471]
there is some evidence that heavy occupational exposure to wood dust may be a factor in the development of the condition under consideration.22472 the veteran's malignant neoplasm of the nasopharynx is a nasopharyngeal carcinoma.
the veteran has been heavily occupationally exposed to wood dust at some time. the veteran has been heavily occupationally exposed to wood dust before the clinical onset of malignant neoplasm of the nasopharynx.22476 — the veteran has established the causal connection between the heavy occupational exposure to wood dust and VEA service for the clinical onset of malignant neoplasm of the nasopharynx.
22477 — the veteran has established the causal connection between the heavy occupational exposure to wood dust and operational service for the clinical onset of malignant neoplasm of the nasopharynx.
or
22478 — the veteran has established the causal connection between the heavy occupational exposure to wood dust and eligible service for the clinical onset of malignant neoplasm of the nasopharynx.
Clinical onset and operational service [22477]
the veteran has been heavily occupationally exposed to wood dust for a period or periods of time totalling at least 10 years before the clinical onset of malignant neoplasm of the nasopharynx. operational service made a material contribution to the veteran being heavily occupationally exposed to wood dust for a period or periods of time totalling at least 10 years before the clinical onset of malignant neoplasm of the nasopharynx.Clinical onset and eligible service [22478]
the veteran has been heavily occupationally exposed to wood dust for a period or periods of time totalling at least 20 years before the clinical onset of malignant neoplasm of the nasopharynx. eligible service made a material contribution to the veteran being heavily occupationally exposed to wood dust for a period or periods of time totalling at least 20 years before the clinical onset of malignant neoplasm of the nasopharynx.
