Agent Orange exposure is a recognized risk factor for several types of bone marrow cancers, and is a presumptive condition for U.S. veterans seeking health and disability benefits. These include multiple myeloma and, based on recent research, myelodysplastic syndromes (MDS).
Confirmed Bone Marrow Cancers:
VA officially recognizes the following bone marrow-related conditions as presumptively linked to Agent Orange exposure:
1. Multiple Myeloma: This is a cancer of the plasma cells, a type of white blood cell found in the bone marrow. The VA considers it a presumptive condition, which means affected veterans do not have to prove a direct connection between their service exposure and the disease to be eligible for benefits.
2. Chronic B-cell Leukemias: This group of blood cancers affects B-cells, which also originate in the bone marrow and are part of the immune system.
Emerging Evidence: Myelodysplastic Syndromes (MDS):
Until recently, the link between Agent Orange and myelodysplastic syndromes (MDS) was less clear, creating barriers for veterans seeking care and disability benefits. However, significant new research, presented at the 2025 American Society of Hematology annual meeting and published in the journal Blood, has established a strong association.
The study identified genetic mutations tied to earlier diagnosis and faster progression of the disease, he said. “What we’re seeing is that Agent Orange added a mutation — and that mutation sets patients on the road to cancer 50 years later,” researchers stated.
These findings are expected to help formalize the recognition of MDS as a presumptive condition, aiding veterans in accessing the care they need.
Key findings from this research indicate that exposed veterans:
• Have a higher risk of developing MDS.
• Tend to be diagnosed at a younger age.
• Exhibit more aggressive forms of the disease with a higher number of harmful genetic mutations.
• Are nearly twice as likely to see their condition progress to acute myeloid leukemia (AML).
Actionable Steps for Veterans:
If you or a loved one are a veteran who was exposed to Agent Orange and have been diagnosed with a bone marrow cancer:
• Check Eligibility: Veterans who served in specific areas (e.g., Vietnam, the Korean DMZ) during defined time frames are presumed to have been exposed.
• Apply for Benefits: You may be eligible for VA health care and disability compensation. You can learn more about the process and eligible conditions on the official VA Public Health website. While many health problems such as MDS are not recognized by VA as presumptively associated with Agent Orange exposure, a claim can proceed for a case-by-case adjudication. This MDS study can help support such a claim. Seek help from an accredited veterans service officer, such as from DAV, VFW, state or local governments.
• Seek Specific Care: The findings from recent studies suggest that Agent Orange-related MDS has unique genetic patterns, which might influence specific treatment decisions. Consult with a hematology specialist. Make sure your health care providers are aware of your Agent Orange exposure history!
• Get an Exam: Eligible veterans can receive a free Agent Orange Registry health exam to document exposure-related health concerns.
