Thyroid Cancer (Radiation): VA Presumptive Condition (Ionizing Radiation)
VeteranHQ lists Thyroid Cancer (Radiation) as a presumptive condition in the Ionizing Radiation group. The exposure it is tied to is: Ionizing radiation — radioiodine (I-131) and external gamma radiation to the thyroid. The presumption is effective September 26, 1994. It is governed by 38 CFR § 3.309(d); 38 USC § 1112(c); Public Law 100-321.
A presumption removes one requirement and one only: the veteran does not have to prove a medical link between the condition and service. Everything else still applies. There must be a current diagnosis, the service has to meet the requirements below, and VA decides the claim on the evidence in the record.

About this presumption
Thyroid cancer is among the most strongly radiation-associated cancers, particularly for childhood/young adult exposure to radioiodine (I-131 fallout) and external gamma radiation. The thyroid gland is one of the most radiosensitive tissues in the body. The Chernobyl accident data and atomic bomb survivor data both confirm the dose-response relationship. The delay between radiation exposure and thyroid cancer diagnosis may be decades. Covers papillary, follicular, medullary, and anaplastic thyroid carcinoma, as well as differentiated thyroid cancers.
Evidence still needed
A presumption does not remove the evidence requirement. VA still needs a current diagnosis from a medical provider and service records that show the qualifying service above. What it removes is the medical opinion connecting the two.
Service records confirming radiation-risk activity; thyroid ultrasound; fine needle aspiration cytology (FNA) or surgical pathology confirming thyroid malignancy with histological type; endocrinology/surgery records; TSH, Free T4 levels; radioiodine treatment records if applicable.

Questions About Thyroid Cancer (Radiation) and Presumptive Service Connection
Is Thyroid Cancer (Radiation) a VA presumptive condition?
Yes. VeteranHQ lists Thyroid Cancer (Radiation) as presumptive in the Ionizing Radiation group, effective September 26, 1994, under 38 CFR § 3.309(d); 38 USC § 1112(c); Public Law 100-321. A presumption removes the requirement to prove a medical link to service. A current diagnosis and qualifying service are still required, and VA decides the claim.
What service qualifies for the Thyroid Cancer (Radiation) presumption?
Participation in a radiation-risk activity as defined in 38 CFR § 3.309(d)(3). Service era: WWII era through 1990s. Service location: Hiroshima/Nagasaki, atmospheric nuclear test sites, Enewetak Atoll.
What evidence is still needed for a Thyroid Cancer (Radiation) claim?
Service records confirming radiation-risk activity; thyroid ultrasound; fine needle aspiration cytology (FNA) or surgical pathology confirming thyroid malignancy with histological type; endocrinology/surgery records; TSH, Free T4 levels; radioiodine treatment records if applicable. A presumption removes the requirement to prove a medical link to service. A current diagnosis and qualifying service are still required, and VA decides the claim.
Is there a filing deadline for Thyroid Cancer (Radiation)?
No statutory deadline
