Abstract Objective: To examine cancer incidence in 1,482 Air Force veterans who served in Southeast Asia (SEA) and were not occupationally exposed to herbicides.

Methods: Cancer incidence between 1982 and 2003 was determined by record review and Cox proportional hazards models were used to estimate risk ratios across serum TCDD and years served in SEA categories.

Results: All sites cancer risk increased with TCDD (RR=1.6, 95% CI 1.2-2.2). The risk of prostate cancer increased with years of SEA service but not with TCDD. TCDD and years of SEA service interacted with all sites cancer; the risk was greatest in those with the highest TCDD levels and the longest time served in SEA.

Conclusions: These results suggest non-occupational exposures to TCDD or other factors while in SEA may contribute to cancer risk in these veterans.
