VA has processed more than 3 million PACT Act-related claims since the law took effect in August 2022, and the approval rate for toxic-exposure conditions climbed from roughly 25% before the law to about 78.6% in the PACT Act's first year. Yet thousands of veterans holding a qualifying cancer diagnosis still have not filed, because the presumptive cancer list is spread across two dozen medical categories with no plain-English map. That gap costs families money and time they cannot recover. This guide lays out the 2026 presumptive cancer list by body system, the service locations and dates that trigger the presumption, and the filing sequence that protects an effective date from day one.
Key Takeaways
- Confirm qualifying service first — the presumption turns on where and when a veteran served, not on proof of exposure.
- Match the diagnosis to one of the 23 PACT Act condition categories, which together cover more than 330 individual conditions.
- Recognize that VA has stated its published cancer lists are not exhaustive — related diagnoses may still qualify.
- Track the newer additions: three cancers added in June 2024 and several blood and genitourinary cancers effective in January 2025.
- File an Intent to File before the formal claim to lock the earliest possible effective date.
- Build the medical record — pathology report, diagnosis date, and treatment history — before submission, not after.

Who Qualifies: Service Locations and Dates That Trigger the Presumption
The most common reason a presumptive cancer claim stalls is not the diagnosis — it is the service record. Veterans assume that any deployment counts. It does not. The PACT Act presumption attaches to specific countries, specific bodies of water, and specific date windows. A veteran who served three feet outside those boundaries is not disqualified from compensation, but the automatic presumption will not apply and the claim reverts to the standard direct service-connection pathway requiring a medical nexus opinion.
VA has reported more than 6.6 million toxic exposure screenings completed as of December 31, 2025 — a strong signal that the agency expects far more qualifying veterans than have filed. Screening is not a claim, though. A screening records a conversation with a clinician. A claim is a separate filing that starts the compensation clock.
Gulf War and Post-9/11 Deployment Windows
Two service windows drive burn pit and particulate-matter presumptions. The first covers service on or after August 2, 1990, on the ground or in the airspace above Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, Somalia, the United Arab Emirates, the Arabian Sea, the Gulf of Aden, the Gulf of Oman, the neutral zone between Iraq and Saudi Arabia, the Persian Gulf, or the Red Sea.
The second covers service on or after September 11, 2001, on the ground or in the airspace above Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Uzbekistan, or Yemen.
Airspace counts. Aircrew who flew missions over these locations without ever setting boots on the ground fall inside the window. So do sailors in the listed waters. The evidence that proves this is usually a DD-214, deployment orders, flight records, or a personnel file entry — not a memory. Veterans should pull those documents before filing and confirm current eligibility on VA.gov, because location and date lists have been amended more than once since 2022.
The 2026 Presumptive Cancer List by Body System
The PACT Act created what VA officials have described as 23 categories of presumptive conditions, encompassing more than 330 medical conditions in total. Many veterans scan a short summary list, do not see their exact diagnosis, and stop. That is the costly mistake. VA has stated plainly that its published cancer lists are not complete lists of the cancers considered presumptive — the categories are broader than any single bulleted page.
Head, Neck, Brain, Nervous System, and Respiratory Cancers
The brain and nervous system category includes glioblastoma (primary and secondary), anaplastic astrocytoma, brain stem glioma, diffuse and pilocytic astrocytoma, subependymal giant cell astrocytoma, ependymomas, oligodendrogliomas, mixed gliomas, malignant pineal gland tumors, and pituitary carcinoma. Spinal cord cancers include chordoma, chondrosarcoma, Ewing's sarcoma, malignant peripheral nerve sheath tumor, and solitary plasmacytoma.
Head and neck coverage runs through hypopharyngeal, laryngeal, jaw, oral cavity, oropharyngeal, pharyngeal, salivary gland, thyroid, and tongue cancers, plus basal cell carcinoma, squamous cell carcinoma, and melanoma of the skin. Eye and ear cancers — including choroidal, conjunctival, and iris melanoma — are covered as well.
Respiratory cancers cover lung (adenocarcinoma, small cell, large cell, squamous cell, carcinoid, sarcomatoid, and more), bronchial, tracheal, nasopharyngeal, paranasal sinus and nasal cavity, laryngeal, and throat cancers.
Gastrointestinal, Reproductive, Blood, and Genitourinary Cancers
Gastrointestinal coverage includes anal, colorectal, esophageal, liver, pancreatic, small intestine, spleen, stomach, salivary gland, and tongue cancers. Kidney coverage spans renal cell carcinoma of all major subtypes plus renal sarcoma and Wilms tumor.
Reproductive cancers include breast, cervical, ovarian, uterine, vaginal, vulvar, and paraurethral gland cancer for women, and male breast, penile, prostate, and testicular cancer for men. Urethral cancer is covered separately.
Lymphomas — Hodgkin's, non-Hodgkin's, B-cell, T-cell, Burkitt, mantle-cell, lymphoblastic, anaplastic large cell, and mycosis fungoides — are presumptive, as are melanomas of the skin, eye, and mucosal tissue, and soft-tissue sarcomas including Ewing sarcoma, leiomyosarcoma, liposarcoma, osteosarcoma, rhabdomyosarcoma, and angiosarcoma.
Conditions Added Since 2024 and the Non-Cancer Presumptives
The presumptive list is not frozen. The PACT Act requires VA to keep reviewing evidence for future conditions, and the agency has used that authority repeatedly. Veterans who were denied in 2022 or 2023 for a condition that later became presumptive are in a materially different position today than they were then — a fact many never learn because no one sends a notice when a list changes.
In June 2024, VA announced presumptions of service connection for male breast cancer, urethral cancer, and cancer of the paraurethral glands for eligible Gulf War and post-9/11 veterans who deployed to Afghanistan, Somalia, Djibouti, Egypt, Jordan, Lebanon, Syria, Yemen, Uzbekistan, and the broader Southwest Asia theater of operations.
In January 2025, VA extended presumptions further. Urinary bladder, ureter, and related genitourinary cancers took effect January 2, 2025. Acute and chronic leukemias, multiple myelomas, myelodysplastic syndromes, and myelofibrosis took effect January 10, 2025, tied to exposure to fine particulate matter for Gulf War and Southwest Asia theater veterans serving on or after August 2, 1990.
The Twelve Non-Cancer Respiratory and Systemic Presumptives
Cancer is only part of the burn pit list. VA also presumes service connection for asthma diagnosed after service, chronic bronchitis, chronic obstructive pulmonary disease, chronic rhinitis, chronic sinusitis, constrictive or obliterative bronchiolitis, emphysema, granulomatous disease, interstitial lung disease, pleuritis, pulmonary fibrosis, and sarcoidosis.
Separately, the PACT Act added high blood pressure and monoclonal gammopathy of undetermined significance to the Agent Orange presumptive list, and expanded Agent Orange exposure locations to include Thailand, Laos, Cambodia, Guam, American Samoa, and Johnston Atoll during defined periods. Camp Lejeune and MCAS New River service between August 1, 1953 and December 31, 1987 carries its own eight-condition presumptive list.
Filing a Presumptive Cancer Claim: Five Steps
Presumptive status removes the hardest element of a claim — proving the link — but it does not file the claim. VA received more than 1 million PACT Act-related claims in 2025 alone, and the ones that move fastest are the ones submitted complete. Follow a fixed sequence.
Step 1 — File an Intent to File. Submit VA Form 21-0966 or start the claim online. This sets a placeholder effective date and generally preserves up to one year to complete the formal claim.
Step 2 — Pull the service evidence. Gather the DD-214, deployment orders, flight or ship records, and any personnel entry showing presence in a qualifying location during a qualifying window.
Step 3 — Assemble the medical proof of diagnosis. The pathology report, oncology notes, imaging, and the date of diagnosis are the core. Presumptive claims still require a current, documented diagnosis.
Step 4 — Complete VA Form 21-526EZ. Name the specific cancer, cite the PACT Act presumption, and list every secondary or residual condition — surgical scars, neuropathy, fatigue, medication side effects.
Step 5 — Submit and confirm receipt. File online at VA.gov or through a VA-accredited representative, then verify the claim appears in the claim status tracker within a few days.
Standard Claim vs. Fully Developed Claim
A Fully Developed Claim asks the veteran to supply all private evidence up front in exchange for faster handling. For presumptive cancers, where the records are usually concentrated with one oncology practice, the FDC route often fits well. A Standard Claim keeps VA's duty to assist in gathering records fully engaged and is the safer choice when records are scattered across multiple providers or decades.
Why Every Residual Matters
Cancer ratings frequently change after active treatment ends. Residual conditions — removed organs, chronic pain, lymphedema, incontinence, hormone effects — are rated separately and are commonly the difference between a modest combined rating and a substantially higher one. Claim them by name at the outset.
After Filing: Exams, Decisions, and Survivor Claims
Waiting is where most veterans lose ground, because nothing on the claim status screen explains what to do next. VA has reported that PACT Act claims are being decided roughly 65% faster than traditional disability claims, but "faster" is not "instant," and the steps after filing carry real decisions.
The C&P Exam and the Rating Decision
VA will usually schedule a Compensation and Pension examination to assess severity and residuals — not to re-litigate whether service caused the cancer, which the presumption already answers. Attend it. Describe symptoms on the worst days, not the best ones, and bring a written list of residuals so nothing is forgotten under time pressure.
The rating decision letter identifies each condition, the assigned percentage, the effective date, and the reasons and bases. Read the effective date line first — it controls back pay. Active malignancy is often rated at a high temporary level, with a scheduled future examination to re-rate based on residuals once treatment concludes.
Denials and Survivor Claims
A denial on a presumptive claim usually traces to one of three gaps: unproven qualifying service, a diagnosis VA did not match to a listed category, or missing medical records. Each has a distinct remedy under the Appeals Modernization Act — Supplemental Claim, Higher-Level Review, or Board appeal.
Surviving spouses, dependent children, and dependent parents may be eligible to file for Dependency and Indemnity Compensation when a service-connected presumptive cancer contributed to a veteran's death, including in cases where the veteran never filed. Those claims are filed separately and have their own evidence requirements.
Take the Next Step
A presumptive cancer diagnosis is one of the few situations where the hardest part of a VA claim is already decided in the veteran's favor — and it is still the situation where families most often wait, assume they do not qualify, or file without the residuals that carry the rating. The fix is preparation, not luck.

Frequently Asked Questions
Does a presumptive cancer still require a medical nexus letter?
Generally no. The purpose of a presumption is to remove the nexus requirement. When qualifying service and a listed diagnosis are both established, VA presumes the connection rather than asking the veteran to prove it. A nexus opinion becomes relevant again in two situations: when the specific diagnosis does not clearly fall inside a listed category, or when the veteran's service does not fall inside a qualifying location and date window. In those cases the claim proceeds on a direct service-connection theory, and a private medical opinion linking the condition to service can carry significant weight. Confirm the current list on VA.gov before deciding whether an opinion is needed.
What if the exact cancer is not on the published list?
Do not stop. VA has stated that its published burn pit cancer lists are not complete lists of the cancers considered presumptive. The presumptions are organized as broad categories — respiratory cancers, gastrointestinal cancers, reproductive cancers, lymphomas, melanomas, sarcomas, and others — and many specific diagnoses fall inside a category without appearing by name. A rare subtype of a listed organ cancer is a common example. Where a diagnosis genuinely falls outside every category, the standard direct service-connection pathway remains available with medical evidence and an exposure history. Verifying the current categories on VA.gov before filing is the reliable move.
Can a veteran refile after being denied before the list expanded?
Yes, and this is one of the most overlooked openings in the entire PACT Act. Conditions added in June 2024 and January 2025 did not exist as presumptions when many veterans were first denied. A new presumption is generally treated as new and relevant information for purposes of a Supplemental Claim. Veterans denied for male breast cancer, urethral cancer, paraurethral gland cancer, bladder or ureter cancer, leukemias, multiple myeloma, myelodysplastic syndromes, or myelofibrosis before those effective dates should review the prior decision closely. Effective-date rules for retroactive awards are technical, so a VA-accredited representative is worth consulting before filing.
Does airspace-only service count for burn pit presumptions?
Yes. The qualifying language covers service on the ground or in the airspace above the listed locations. Aircrew, aeromedical evacuation personnel, and others who flew missions over qualifying countries without ground time fall inside the window, as do personnel serving in the listed waters. The practical challenge is documentation. Flight records, aircraft mission logs, unit histories, and personnel file entries carry more weight than recollection alone. Veterans should request their military personnel file early, because assembling flight documentation frequently takes longer than gathering medical records and is the step most likely to delay an otherwise strong claim.
How does the diagnosis date affect a presumptive cancer claim?
Diagnosis date matters in two ways. First, it establishes that a current disability exists, which every claim requires regardless of presumption. Second, some presumptive frameworks carry manifestation timeframes tied to separation from service. Because these rules differ by exposure category and have been amended since 2022, the diagnosis date, the separation date, and the applicable presumption should be checked together on VA.gov rather than assumed. The effective date of the award is a separate question driven mainly by when the Intent to File or claim was submitted, which is why filing an Intent to File promptly is such a consistent recommendation.
Are non-cancer conditions treated differently from presumptive cancers?
The eligibility logic is the same — qualifying service plus a listed diagnosis — but the evidence pattern differs. The twelve non-cancer burn pit presumptives, including asthma diagnosed after service, COPD, chronic sinusitis, chronic rhinitis, constrictive bronchiolitis, emphysema, interstitial lung disease, pleuritis, pulmonary fibrosis, sarcoidosis, granulomatous disease, and chronic bronchitis, are usually rated on pulmonary function testing and symptom frequency rather than on staging and treatment history. That means recent PFT results and a documented symptom history often drive the rating far more than the diagnosis paperwork alone. Both types of claim benefit from a written symptom record kept over time.
What can survivors do when the veteran never filed?
Survivors are not shut out. Surviving spouses, dependent children, and in some circumstances dependent parents may be eligible to file for Dependency and Indemnity Compensation when a service-connected condition — including a presumptive cancer — caused or contributed substantially to the veteran's death. The claim is filed by the survivor and requires the veteran's service records, the death certificate, medical records establishing the condition, and proof of the family relationship. Because the PACT Act made conditions presumptive that were not presumptive at the time of many deaths, families who were previously told there was no claim should re-examine eligibility on VA.gov or with a VA-accredited representative.
