A study of Veterans Health Administration records finds that U.S. veterans diagnosed with cancer face a markedly higher chance of attempting suicide, with the greatest vulnerability in the months after diagnosis and elevated risk continuing for years. Published in JAMA Oncology, the research highlights gaps in mental-health support for people navigating cancer and survivorship.

Researchers at Oregon Health & Science University analyzed VHA data for more than 292,000 veterans diagnosed with cancer between 2014 and 2023. They measured incidents of **suicidal self-directed violence (SSDV)** — including both fatal and nonfatal attempts — and compared those rates to population baselines.
The team found a reported rate of roughly 203 SSDV events per 100,000 veterans with cancer, a level the authors say exceeds general-population figures. The study is observational, meaning it shows an association rather than direct cause-and-effect.
When the risk is highest — and how long it lasts
Risk peaked within the first six months after a cancer diagnosis but did not end there. The elevated likelihood of suicidal behavior persisted for as long as five years after diagnosis in the dataset, underscoring that distress can extend well into survivorship.
- Periods of heightened risk: first six months after diagnosis, then sustained increase lasting up to five years.
- Groups with higher SSDV rates: veterans with severe frailty, chronic mental-health conditions, advanced-stage cancers, or high reported pain.
- Demographics with more nonfatal attempts: veterans under 45, female veterans, and those with central nervous system or thyroid cancers.
- Methods observed: prescription drugs (including opioids) were most common in nonfatal attempts; firearms were most common in fatal attempts.
The study authors stress that medical shock, treatment side effects, ongoing pain and mood disorders can create a cascade of distress after a cancer diagnosis. Lead author Donald R. Sullivan, MD, described the pattern as a significant public-health concern that disproportionately affects service members and veterans.
Implications for care and prevention
Clinically, the findings point to a need for routine mental-health screening and early intervention for veterans at the point of cancer diagnosis — not only during active treatment but also throughout follow-up and long-term survivorship care.
Outside commentators who were not part of the research urged a coordinated response. Whaley emphasized the importance of investigating upstream factors and sharing findings with veteran support organizations in communities, calling for combined efforts in research, outreach and clinical care. He also warned that many veterans, while adept at supporting peers, may be reluctant to seek help themselves.
As one practical takeaway, oncology and primary-care teams treating veterans might consider rapid mental-health assessment in the weeks following diagnosis, greater attention to pain management, safer medication practices and targeted support for patients with disabilities or preexisting psychiatric diagnoses.
What remains unsettled
The study cannot prove that cancer causes suicidal behavior; it identifies patterns and groups at increased risk. Further research is needed to untangle how clinical, social and economic factors interact after diagnosis and which interventions most effectively reduce risk.
Researchers and advocates say the findings support urgent policy and programmatic responses — from improved screening protocols in VA and non-VA clinics to broader community outreach — to address a preventable source of harm among veterans living with cancer.
