Dioxins (Agent Orange family)
ContaminantIARC Group 1Persistent toxicants from herbicides like Agent Orange and from burning plastics in burn pits.
Where it comes from in service
Vietnam, the Thailand base perimeters, the Korean DMZ, herbicide test/storage sites, and burn-pit plastic combustion.
How it harms the body
Dioxin (TCDD) stores in body fat for years and interferes with hormone and cellular regulation, which is why its recognized effects span cancers, diabetes, heart disease, and nerve injury.
How long it stays in you
Half-life of several years in body fat — a single era of exposure can stay biologically relevant for decades.
Where it goes — tap an organ to go deeper
The Agent Orange presumptive list (38 CFR §3.309(e)) recognizes many conditions, including several cancers, type 2 diabetes, ischemic heart disease, hypothyroidism, Parkinson's, and early-onset peripheral neuropathy.
Recognized chronic diseases can surface decades later; the Agent Orange presumptive list is strong government acknowledgment for a claim.
What to ask your clinician about
- •Condition-specific screening with your clinician
- •Hormone and metabolic markers
Bring this to your clinician and your VSO — they decide what testing and care, if any, is right for you. For general, whole-person ways to support your body, see Whole health.
