The short answer
The Commission on Cancer is a program of the American College of Surgeons that accredits cancer programs against more than 30 patient-centered standards. Nearly 1,400 US hospitals and cancer centers are accredited, and they treat more than 74% of newly diagnosed patients each year. You can look up whether a specific hospital is accredited using the Find a Hospital search.
The CoC is described as a consortium of professional organizations dedicated to improving survival and quality of life for patients with cancer.
Accredited programs must meet a core set of more than 30 standards spanning screening through survivorship or end-of-life care.
Nearly 1,400 hospitals and cancer centers in the US are CoC accredited, and they treat more than 74% of recently diagnosed patients annually.
Accredited programs undergo a site visit every three years to keep accreditation.

The full explanation.
A question people actually ask
"Is my hospital a real cancer center?" It comes up quietly, usually after the first appointment, often from a family member who has been searching at night.
There is a partial answer you can look up. The Commission on Cancer, a program of the American College of Surgeons, accredits cancer programs. Nearly 1,400 hospitals and cancer centers in the United States hold that accreditation, and CoC-accredited facilities treat more than 74 percent of recently diagnosed patients with cancer each year.
So the odds are decent that your hospital is on the list. It is worth ten seconds to check.
What the CoC is
The CoC describes itself as a consortium of professional organizations dedicated to improving survival and quality of life for patients with cancer. It is a multidisciplinary accreditation program, and that word multidisciplinary is the heart of it.
The idea is not that one surgeon is excellent. The idea is that surgery, medical oncology, radiation oncology, pathology, radiology, nursing, social work and record-keeping all function together, for every patient, not just the interesting ones.
What the standards ask for
Programs must meet a core set of more than 30 standards. The CoC says these standards help improve the quality of care through cancer-related programs and activities, and that they address the full patient journey, from screening through survivorship or end-of-life care.
That range is the point. A program is not judged only on how it treats disease. It is also judged on what happens before diagnosis and after treatment ends, which are precisely the stretches where patients most often feel dropped.
How a program earns and keeps it
This is not a one-time badge.
A new applicant has to show one calendar year of compliance before it can even submit. It needs a complete calendar year of abstracted data and a complete year of follow-up data, which means the program has to be tracking its own patients over time. If any standard is out of compliance, corrective action must be completed before accreditation is granted.
After that, accredited programs undergo a site visit every three years.
There are twelve program categories, and several are defined by volume. An academic comprehensive cancer program accessions more than 500 newly diagnosed cases a year. A comprehensive community cancer program has 500 or more. A community cancer program has more than 100 but fewer than 500. A hospital associate cancer program has 100 or fewer. Other categories cover free-standing centers, integrated networks, NCI-designated programs, pediatric programs, rural programs and Veterans Affairs facilities.
Those categories are useful to you for one reason. They tell you roughly how many cancer patients a place sees in a year.
What the CoC can do for you today
You can look up your hospital. The CoC points to the American College of Surgeons Find a Hospital search, with a filter for CoC-accredited facilities, and links to that filtered list from its own page. Search the name of your hospital and see whether it appears.
If it does, you can reasonably expect certain things to exist and can ask about them by name: a cancer registry that follows you over time, case review in a multidisciplinary setting, and attention to survivorship. Asking "will my case be discussed at a cancer conference?" is a fair question at an accredited program.
If it does not appear, you have not learned that the hospital is bad. You have learned that this particular accreditation is not held there, which is a reasonable thing to ask about.
The CoC also reports outcome differences at accredited hospitals: a 9 percent lower mortality rate, and patients 79 percent more likely to receive guideline-based care. Treat those as program-level statistics, not a prediction about you.
What accreditation cannot tell you
It cannot tell you whether your oncologist is the right oncologist for you. Accreditation looks at systems, not at individuals.
It cannot promise a good outcome. Averages across nearly 1,400 programs and hundreds of thousands of patients say nothing certain about one person's disease.
It does not mean every treatment is available on site. A small accredited program may need to refer you elsewhere for a complex operation or a clinical trial. That is not a failure, but it is worth asking about early rather than late.
And a site visit happens every three years. A lot can change in a hospital in three years, in either direction.
The more useful move
Use accreditation as an opening, not an answer. Look it up, then ask the human questions it makes possible. How many cases like mine do you treat here? Will my case be reviewed by more than one specialty? Is there a navigator? Where would you send me if I needed something you do not do?
Those answers will tell you more about your care than any seal will.

Common questions
How do I check whether my hospital is CoC accredited?
Use the American College of Surgeons Find a Hospital search and filter for CoC-accredited facilities. The CoC links directly to that filtered list from its own page.
What do the standards actually cover?
The CoC says programs must meet more than 30 standards that address the full patient journey, from screening through survivorship or end-of-life care.
How often is a program checked?
Accredited programs undergo a site visit every three years. New applicants must show a calendar year of compliance, with a full year of abstracted and follow-up data, before accreditation is considered.
Does the size of a program matter?
The categories are partly defined by volume. A community cancer program is described as more than 100 but fewer than 500 newly diagnosed cases a year, while an academic comprehensive program has more than 500.
Is a non-accredited hospital a bad choice?
Not necessarily. Many good hospitals are not accredited, and geography and insurance often decide where you go. It is a useful data point, not a verdict.
Is this the same as being an NCI-designated cancer center?
No, they are different things run by different bodies. NCI-designated programs appear as one of the CoC's own program categories, so a hospital can hold both.
Does accreditation guarantee my care will be good?
No. It describes what a program has in place across many patients. It cannot promise anything about your individual doctor, your wait times or your outcome.

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.

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.
