The short answer
The PACT Act added more than 20 presumptive conditions for burn pits, Agent Orange, and other toxic exposures. Eleven cancer categories are now presumptive for Gulf War era and post-9/11 veterans, including brain, kidney, pancreatic, and any lymphoma, melanoma, or reproductive, respiratory, head, neck, or gastrointestinal cancer. A presumptive condition removes the need to prove service caused it.
For a presumptive condition, a veteran does not have to prove that service caused it — only that the service requirements are met.
Eleven cancer categories are presumptive for burn pit exposure, including brain, kidney, pancreatic, melanoma, and any lymphoma, gastrointestinal, head, neck, reproductive, or respiratory cancer.
Presumed burn pit exposure covers service on or after September 11, 2001, in eight named countries, and on or after August 2, 1990, in eight more.
The PACT Act requires the VA to provide a toxic exposure screening to every veteran enrolled in VA health care.

The full explanation.
What "presumptive" actually means
This is the word that decides how hard a claim is, and the VA defines it plainly.
For most health conditions, a veteran must prove that service caused it. For a presumptive condition, the VA assumes it did.
So only one thing is left to show. That is the service requirement. It means being in the right place, at the right time, in the right role. The medical argument is already settled by law or regulation.
The law that changed the lists
The PACT Act is the current framework. Its full name is long. It is the Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics Act. The VA calls it perhaps the largest health care and benefit expansion in its history.
What it does:
- Widens VA health care eligibility for veterans with toxic exposures. That spans the Vietnam, Gulf War, and post-9/11 eras.
- Adds more than 20 presumptive conditions for burn pits, Agent Orange, and other toxic exposures.
- Adds more presumptive-exposure locations for Agent Orange and for radiation.
- Requires the VA to provide a toxic exposure screening to every veteran enrolled in VA health care.
- Supports research, staff education, and treatment related to toxic exposures.
That fourth item is worth acting on. The screening is required. It is not an extra that has to be requested.
The cancers now presumptive for burn pit exposure
For Gulf War era and post-9/11 veterans, the VA lists these cancers as presumptive:
- Brain cancer.
- Gastrointestinal cancer of any type.
- Glioblastoma.
- Head cancer of any type.
- Kidney cancer.
- Lymphoma of any type.
- Melanoma.
- Neck cancer of any type.
- Pancreatic cancer.
- Reproductive cancer of any type.
- Respiratory cancer of any type.
Notice how broad several of those entries are. The phrase "of any type" appears six times. So a specific diagnosis need not be named on the list. It only has to fall inside one of those groups.
The same list holds non-cancer conditions too. Those are asthma diagnosed after service, chronic bronchitis, and COPD. Also chronic rhinitis, chronic sinusitis, and constrictive or obliterative bronchiolitis. Also emphysema, granulomatous disease, and interstitial lung disease. Also pleuritis, pulmonary fibrosis, and sarcoidosis.
Where and when exposure is presumed
Location and dates do the work here. The VA presumes burn pit or other toxic exposure in these places.
First, service on or after September 11, 2001. The countries are Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Uzbekistan, and Yemen. The airspace above them counts too.
Second, service on or after August 2, 1990. The countries are Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, Somalia, and the United Arab Emirates. Again, the airspace above them counts.
Some deployments also count. Those are Operation Enduring Freedom, Operation Freedom's Sentinel, and Operation Iraqi Freedom. Also Operation New Dawn, Operation Inherent Resolve, and the Resolute Support Mission.
The VA adds one more path. Eligibility may also follow from exposure during training or active duty service. Other factors can count as well.
Agent Orange, and what the PACT Act added
Two new presumptive conditions were added for Agent Orange. One is high blood pressure. The other is monoclonal gammopathy of undetermined significance, known as MGUS.
Five new presumed-exposure locations were also added:
- Any US or Royal Thai military base in Thailand, January 9, 1962 through June 30, 1976.
- Laos, December 1, 1965 through September 30, 1969.
- Cambodia at Mimot or Krek, Kampong Cham Province, April 16 through April 30, 1969.
- Guam or American Samoa, or their territorial waters, January 9, 1962 through July 31, 1980.
- Johnston Atoll, or a ship that called there, January 1, 1972 through September 30, 1977.
The VA notes this is not the complete list of presumptive locations for Agent Orange.
On the cancer side, the Agent Orange list is specific. It includes cancers of the lung, larynx, trachea, and bronchus. It also includes soft tissue sarcomas. Four are excluded: osteosarcoma, chondrosarcoma, Kaposi sarcoma, and mesothelioma. Our page on Kaposi sarcoma covers one of those exclusions.
Radiation exposure locations added
Three response efforts were added to the presumed radiation exposure list:
- Cleanup of Enewetak Atoll, January 1, 1977 through December 31, 1980.
- Cleanup after the B-52 crash off Palomares, Spain, January 17, 1966 through March 31, 1967.
- Response to the B-52 fire near Thule Air Force Base in Greenland, January 21 through September 25, 1968.
Other radiation presumptive locations exist beyond these three.
Enrolling in VA health care
One rule removes a common obstacle. A veteran can enroll in VA health care now. There is no need to apply for disability benefits first. The basic service and discharge requirements must be met. And one of the descriptions above must apply.
The VA's wider eligibility statement covers three groups. One is service in the Vietnam War, the Gulf War, Iraq, Afghanistan, or any combat zone after 9/11. One is deployment in support of the Global War on Terror. One is exposure to toxins or hazards during service, at home or abroad.
Even outside those categories, other paths to VA health care exist based on service.
Why to say it out loud in a cancer clinic
Two reasons, and they are different from each other.
The first is medical. Service history changes which exposures a care team weighs. It changes which screenings make sense. Decades can pass between an exposure and a diagnosis. That is long enough for the link to stop feeling relevant.
The second is money and paperwork. A cancer in a presumptive category may open both health care and disability pay. No causation fight is needed. And if a claim was denied years ago, the lists have changed since.
Three phone numbers are worth having. VA health care is 877-222-8387. VA benefits is 800-827-1000. The PACT Act line is 800-698-2411. Claims can be filed online, by mail, in person, or with help from a trained representative. Our page on paying for cancer treatment covers the wider financial picture.

Common questions
Which military exposures are linked to cancer?
The VA names burn pits, sand and dust, particulates, oil well or sulfur fires, chemicals, radiation, warfare agents, depleted uranium, herbicides such as Agent Orange, and other occupational hazards. Which ones apply depends on where and when a person served.
Can I get cancer care through the VA?
Many veterans are eligible for healthcare through the VA, which includes cancer care. Eligibility depends on factors like service history and enrollment. A VA benefits counselor or veterans service organization can help you understand whether you qualify and how to enroll.
What does it mean for a cancer to be 'presumptive'?
The VA explains it directly: for most conditions a veteran must prove service caused the condition, but for presumptive conditions the VA automatically assumes it did. Only the service requirements for the presumption need to be met. Presumptive status is established by law or regulation.
Why should I tell my doctor I'm a veteran?
Your service history may include exposures that raise the risk of certain cancers or that affect which screenings make sense for you. Sharing it, even years later, gives your care team important context and can also point you toward benefits you may be entitled to.
