Vietnam veterans and prostate cancer: a claim map
A claim map for Vietnam veterans: prostate cancer is presumed for herbicide exposure, and erectile dysfunction, bladder problems and special monthly compensation follow from it. How the Board decided each step, and why ship service decides so many denials.
The claim map
A claim map follows one veteran's route: where they served, the condition VA presumes for that service, and the conditions that follow from it. Each box shows how the Board ruled at that step.

Bar: share granted in Board decisions that name Vietnam (one count per veteran; a remand counts as not granted). Red mark: all veterans with the same claim. Step 2 counts claims decided in the same decision; conditions with at least 15 veterans.
Is prostate cancer presumptive for Vietnam veterans?
Yes. Prostate cancer is on the herbicide list in 38 CFR 3.309(e), and VA presumes herbicide exposure for service in the Republic of Vietnam, including its offshore waters as set by the Blue Water Navy Vietnam Veterans Act, from January 1962 to May 1975. In decisions that name Vietnam, the Board granted 41.8% of prostate cancer claims, against 32.3% for all veterans.
The presumption covers the link between the exposure and the cancer, at any time after service. 59,560 Board decisions from 2020 to 2025 name Vietnam; this page counts only claims that name prostate cancer, because the same diagnostic code also covers kidney cancer, which is not on the herbicide list.
Why are so many still denied?
For 238 denials, the Board's note named the exposure in 71.8% of them: the decision names Vietnam, but the Board did not find qualifying service there. About four in ten of those denials mention a ship, naval service or offshore waters; only some waters qualify. A medical link was named in 58.4%.
In the denial below, service aboard the USS Coral Sea did not establish exposure. In the first grant below, the Board found service in Vietnam's territorial waters from the veteran's testimony and a letter written home.
How does VA rate prostate cancer?
Under DC 7528 in 38 CFR 4.115b, at a total rating during treatment. Six months after treatment ends, a VA exam is required; if the cancer has not come back, the rating moves to the residuals, rated as voiding dysfunction or renal dysfunction, whichever is worse.
What conditions follow from prostate cancer?
Erectile dysfunction most often: in the same decisions, the Board granted 68 of 175 (38.9%). Bladder problems were granted for 12 of 35. Erectile dysfunction after prostate cancer also opens special monthly compensation (k) for loss of use of a creative organ (M21-1 VIII.iv.4.A.4).
Does the prostate cancer have to be granted first?
In practice, yes. When the same decision granted the prostate cancer, the Board granted 68 of 81 claims secondary to it (84.0%); when it did not, 2 of 100.
Where the prostate cancer was not on appeal, usually because it was already service connected, 22.6% of the secondary claims were granted.

Recent decisions, with the Board's reasoning as summarized by AI:
- , November 2025: prostate cancer granted on the presumption; service in the territorial waters of Vietnam aboard the USS Oriskany was shown by the veteran's testimony and a letter home.
- , November 2025: prostate cancer granted on presumed herbicide exposure during qualifying Vietnam service; the decision names ships in the Gulf of Tonkin.
- , October 2025: prostate cancer denied for a veteran who served aboard the USS Coral Sea; the Board found no competent evidence of herbicide exposure or another link to service.
What the data cannot tell you
The Vietnam group comes from the places each decision names; it includes ships off the coast that may not qualify. Service-connection claims only; rating appeals are left out. The second step counts only claims decided in the same decision. Denial notes are AI-extracted. These are historical outcomes, not predictions.
For representatives
- Settle the service first: land service, or a ship in qualifying waters, with deck logs, the ship's record and the veteran's letters or statements.
- Once prostate cancer is granted, screen for erectile dysfunction and bladder problems, and check special monthly compensation (k).
- Watch the six-month exam after treatment: a reduction to residuals must follow the rules in .

Board of Veterans' Appeals decisions 2020-2025 (bva_cases_v2 lead basis). The group = decisions whose locations name Vietnam or a place in Vietnam; a mention is not proof of qualifying service. Service-connection issues only (not rating, effective-date or TDIU appeals). Each veteran is counted once per condition, at the best ruling in the decision (granted, then remanded, then denied); grant share = granted / all decided, so a remand counts as not granted. Step 2 counts the group's claims marked secondary to a step-1 condition in the same decision; 'all veterans' is the same count across all decisions. Denial notes are AI-extracted. Historical outcomes, not predictions. Queried October 22, 2026. Every figure in this story is computed from the query results, and the AI-extracted data can contain errors. The figures are fixed as of that date. Related research pages describe their own data dates and methods.

- Granted · Denied · Remanded: back to the regional office
Board of Veterans' Appeals decisions show how VA's highest review body applies 38 CFR and weighs evidence on contested claims.
Each one is an appeal: a regional office decided the claim first, and the veteran appealed. So these rates describe the Board, not a veteran's odds at the regional office, where most claims are decided and whose decisions are not public.
