The short answer
A living will records which life-sustaining treatments you would want if you could not speak for yourself, and under which conditions. It is not a do-not-resuscitate order, which only a clinician can write, and it does not replace naming a health care proxy. State law decides the form.
A living will is a written record of the treatments you would want or refuse if you could not speak for yourself. NCI says these documents typically cover life-sustaining machines, tube feeding and organ donation.
A living will is not a DNR. MedlinePlus says a DNR order is written by a health care provider, so owning a living will does not produce one.
A DNR covers CPR only. MedlinePlus says it carries no instructions about pain medicine, other medicines or nutrition.
NCI says each state has its own advance directive laws, which matters if you travel to a specialist center in another state.

What a living will actually records
This page is for people with cancer, and their families, who are thinking about writing down their treatment wishes. A living will is a written record of the treatments you would want, and the ones you would refuse, if you became too ill to speak for yourself. NCI says these documents typically address life-sustaining machines, do-not-resuscitate orders, tube feeding, fluids and organ donation.
A living will does not have to be one yes-or-no vote on aggressive care. Many people write down the situations in which they would, or would not, want a treatment. Ask your care team to help you think through what applies to your cancer.
This page is educational, not legal advice. Forms and signing rules are set by each state. A hospital social worker, a patient advocate, or a legal aid office can check your paperwork against the rules where you live.
The treatments these forms usually name
NCI says living wills typically address these decisions.
- Life-sustaining machines, such as a breathing machine
- Do-not-resuscitate (DNR) orders, which cover CPR (see below)
- Tube feeding
- Whether to withhold food and fluids
- Organ donation
Ask your care team what each choice would mean in your situation.
Writing down your reasoning, not only a checkbox, can help your family understand your wishes.
A living will is not a health care proxy
These are two different papers, and most people benefit from having both.
A living will speaks for you in writing. A durable power of attorney for health care names a person to speak for you out loud. The National Cancer Institute calls that person a health care proxy or medical power of attorney, and describes the document as one "that allows people to name another person to make decisions about their medical care if they are unable to make these decisions for themselves."
Cancer care throws up questions no form anticipated. A scan shows something new during a hospital stay. A clinical trial slot opens. A named proxy can weigh those choices against what you wrote. A form alone cannot.
The gap that catches families off guard
Here is the point that surprises people most, and it is worth reading twice.
A living will is your statement of wishes. A do-not-resuscitate order, or DNR, is different. MedlinePlus is blunt about it: "A do-not-resuscitate order, or DNR order, is a medical order written by a health care provider." Nobody has to write that order simply because you own a living will.
That gap matters most at home. If an ambulance crew is called to a house, they act on medical orders they can see. MedlinePlus says patients can get a wallet card, bracelet or other documentation for non-hospital settings.
So if you want CPR withheld at home, a living will in a filing cabinet will not do it. Ask your oncology team directly for the order and the out-of-hospital paperwork that goes with it.
Also know what a DNR does not do. MedlinePlus states that it "is specific about CPR. It does not have instructions for other treatments, such as pain medicine, other medicines, or nutrition." Because a DNR covers CPR only, ask your team how it fits with the rest of your care.
State lines and treatment centers
The National Cancer Institute warns that "each state has its own laws regarding advance directives" and that you should follow the laws of the state where you live or are being treated.
Cancer care makes that ordinary advice practical. People routinely travel across state lines to a specialist center for surgery, a transplant, or a trial. Take your documents with you. Hand a copy to the medical records office at the second hospital. Ask whether that state needs its own form or witnesses.
Timing, copies, and changes
NCI advises completing these documents while you are able to, rather than waiting until you are very ill.
MedlinePlus says decisions should be shared with family members and your health care agent. Ask your team to put a copy in your medical record.
You can change your mind at any point. The National Cancer Institute is clear that even after signing, "you can change your mind at any time," and that outdated versions should be destroyed so no one acts on the wrong paper. Revisit the document when:
- Your cancer changes
- You switch to a new line of treatment
- Your proxy moves away or becomes ill
- Your own view of what a good outcome looks like shifts
When to raise this with your team sooner
Bring it up quickly if any of these apply:
- You are days away from a high-risk procedure.
- You are moving care to another state.
- Your named proxy can no longer serve.
- A clinician has raised hospice or comfort-focused care.
Ask outright whether an out-of-hospital order is needed for your situation. Getting an answer in writing costs one conversation and saves your family from guessing.

Common questions
Is a living will the same as a DNR?
No, and this is the gap that catches families out. MedlinePlus states that a do-not-resuscitate order is a medical order written by a health care provider. Nobody has to write one just because you have a living will. If you want CPR withheld at home, ask your team for the order and the out-of-hospital paperwork, such as a wallet card or bracelet.
Do I need a health care proxy as well?
Most people benefit from both. A living will speaks for you in writing. NCI describes a durable power of attorney for health care as a document that allows people to name another person to make decisions about their medical care if they cannot make them themselves. Cancer throws up questions no form anticipated, and a named person can weigh them.
Does a DNR stop my cancer treatment or my pain relief?
No. MedlinePlus says a DNR is specific about CPR and does not have instructions for other treatments, such as pain medicine, other medicines, or nutrition. Other treatments are separate decisions, so ask your team how a DNR fits with your care plan.
What if I am treated in another state?
NCI says each state has its own laws regarding advance directives, and that you should follow the laws of the state where you live or are being treated. Take your documents with you, give a copy to medical records at the second hospital, and ask whether that state needs its own form or witnesses.

AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes, and this is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and then compared with the sources listed on it, looking for statements those sources do not back up. That check is not a sentence-by-sentence record and can miss errors. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one.
