Service connection requires (1) a current diagnosis, (2) an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two under 38 C.F.R. § 3.303. This condition is frequently rated as secondary to Thyroid Cancer or Leukemia under 38 C.F.R. § 3.310.
Conditions resulting from ionizing-radiation exposure during military service, including atmospheric nuclear testing (1945-1962), occupation of Hiroshima/Nagasaki, post-WWII cleanup operations, nuclear accident response, and other documented radiation-risk activities. Specific cancers are presumptive under 38 CFR § 3.309(d) for "radiation-exposed veterans," with additional cancers eligible for service connection on a direct basis under § 3.311 after dose reconstruction.
