The short answer
"No evidence of disease" (NED) means that, with the tests used, doctors can't detect any cancer at this time. It's good news and often a goal of treatment. It isn't the same as "cured," because current tests can't rule out every last cell — which is why follow-up continues.
NED means no cancer can be detected with current tests — a hopeful result.
It is not identical to "cured"; there is always at least a very slight risk of recurrence.
Follow-up appointments and scans continue to watch for any return.
NED is closely related to "complete remission."

What "no evidence of disease" means
No evidence of disease, often shortened to NED, means your current tests cannot find any cancer in your body. MD Anderson describes it as no cancer being currently detectable, based on tests such as scans, blood work or biopsies. It is genuinely good news. It is also a more careful statement than it sounds like at first.
Why "no evidence" is not the same as "no cancer"
NED describes what your tests can detect right now. It is not a guarantee about what is happening at the microscopic level, everywhere in your body. Imaging and blood tests have limits. That is why even with no detectable cancer there is always at least a very slight risk of recurrence. NED means the evidence available says nothing is there. It does not mean nothing could possibly be there.
How NED relates to remission
MD Anderson says "remission" and "no evidence of disease" are probably the closest in meaning, and that terminology varies by doctor. MD Anderson advises asking your oncologist specifically what they mean by each term. It is worth confirming what your own report or conversation means.
Why doctors are careful about the word "cured"
"Cancer-free" suggests more than no detectable cancer. It suggests confidence that no hidden cancer remains. MD Anderson notes there is always at least a very slight risk of recurrence for anyone who has had cancer. MD Anderson also says survivors need ongoing surveillance even after long periods without a return. That is part of why ongoing monitoring continues, even after good news. Ask your oncologist how they use the word "cured" for your cancer.
What NED means for what happens next
Reaching NED does not mean monitoring stops. MD Anderson says cancer survivors need ongoing surveillance, and the type depends on the cancer. Your team will recommend a follow-up schedule for you. NED describes today's evidence, not a permanent state. If you notice new symptoms between visits, call your care team right away.
What to ask your team
- What exactly do you mean by NED or remission in my case?
- What follow-up schedule do you recommend, and why that specific timing?
- What symptoms should I watch for that might suggest recurrence?
- At what point, if any, would you consider using the word "cured" for my situation?

Common questions
Is NED the same as being cured?
Not exactly. NED means nothing is detectable now, and MD Anderson notes there is always at least a very slight risk of recurrence for anyone who has had cancer. Ask your oncologist how they use the word 'cured' for your cancer.
If I'm NED, why do I still need scans?
Because there is always at least a very slight risk of recurrence, and survivors need ongoing surveillance. The type depends on your cancer. Your team sets the schedule.

Review details and limits
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. 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. Low-risk educational or organizational content. Medical facts are cited to authoritative sources.
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. Use this site to understand your situation and to ask better questions of the people treating you.
