ASCO and Cancer.Net: guidelines written for patients

ASCO writes guidelines oncologists use and long ran the patient site Cancer.Net. Here is what ASCO offers patients and where its patient content lives now.

The short answer

ASCO is the professional organization for oncologists and other cancer clinicians. It publishes clinical practice guidelines, journals and the research presented at its meetings. Its patient-facing site, Cancer.Net, now redirects to a joint resource built with the American Cancer Society, where ASCO oncologists contribute and vet the content.

  • ASCO is described as the leading organization for cancer care providers.

  • ASCO produces clinical practice guidelines, journals, and the abstracts and presentations from its meetings.

  • Cancer.Net was ASCO's patient education site; that address now redirects to a joint resource with the American Cancer Society.

  • ASCO and the American Cancer Society say they are collaborating to create a single online resource of authoritative cancer information for patients.

The whole article, with every detail and caution.

This page is for patients and families who keep seeing the names ASCO and Cancer.Net. It explains who ASCO is, where its patient site went, and what it can and cannot do for you.

Who ASCO is

ASCO stands for the American Society of Clinical Oncology. It is described as the leading organization for cancer care providers.

That is a mouthful. Here is the plainer version. ASCO is the club your oncologist belongs to, and it is where a great deal of cancer knowledge gets organized and shared.

The four things it produces

Most of what ASCO does falls into four buckets:

  • Clinical practice guidelines. These are recommendations for how to treat particular situations, based on reviewed evidence.
  • Journals, which is where completed studies appear in full.
  • Meetings. ASCO posts the abstracts (short study summaries), posters, slides, and videos from them. A lot of new cancer research becomes public for the first time at an ASCO meeting. That is why you see the acronym in news stories every spring.
  • Education for clinicians, so the people treating you keep learning.

Where the patient site went

For many years, ASCO's patient education site was Cancer.Net. If you were treated a while ago, or if a nurse handed you a printout, you may know the name.

That address now redirects. Going to cancer.net sends you to the American Cancer Society's site instead. The two organizations describe a collaboration to make it simpler for patients to find authoritative cancer information by creating a single, online resource. The two organizations say the joint resource combines their clinical expertise so that patients get information vetted by cancer care specialists.

So the ASCO patient content did not disappear. It moved in with a roommate.

If you have an old bookmark or an old handout with a Cancer.Net web address on it, do not assume the page is gone. Let the redirect carry you, then search for your cancer type on the site you land on.

What ASCO can do for you today

Three practical things.

You can read patient-facing cancer information on cancer.org, which the American Cancer Society says is free to the public. Start from the redirect and look for your cancer type or your treatment.

You can find out what the professional guidance for your situation says. ASCO guidelines are written for clinicians, so the language can be dense. Your care team can explain what they mean for you.

And you can look at what was presented at recent ASCO meetings. If you have heard about a promising drug, the abstract is often the actual source underneath the headline, and it will be more careful than the headline was.

There is a fourth, quieter use. Knowing ASCO exists gives you a fair question to ask in the room. "Is there an ASCO guideline for this?" is not a challenge. It is a reasonable request for context.

What ASCO cannot do for you

ASCO does not treat anyone. There is no ASCO clinic, no ASCO doctor who will look at your scans, no ASCO staffer who can review your case.

It will not tell you whether your oncologist made the right call. Guidelines describe reasonable approaches for groups of people. Your situation includes details no guideline knows about.

It does not run a patient helpline for medical questions, and it cannot help with your bill, your insurance denial or your travel. Those needs are real, and other organizations handle them.

It also cannot promise the newest research is settled. A meeting abstract is early. Sometimes the finding holds up and changes practice. Sometimes it does not.

A note on reading research yourself

Some people find enormous comfort in going to the source. If that is you, ASCO's material is a good place to go, because it is written by people who treat this disease rather than people selling something.

But abstracts are compressed and technical, and it is easy to read a hopeful sentence about a small early study and carry it into your next appointment as though it were a promise.

A better move is to print the page, bring it, and ask one question. Does this apply to me? Your oncologist can answer that in a minute, and you will have spent your energy well.

Common questions

Is Cancer.Net still a website?

Typing cancer.net now sends you to the American Cancer Society site. ASCO and the American Cancer Society describe a collaboration to make one online resource for authoritative cancer information rather than two.

Who writes the patient information ASCO is involved in?

The two organizations say the joint resource draws on their combined clinical expertise so that patients get information vetted by cancer care specialists.

What does ASCO actually do?

It is a professional society. It publishes guidelines, journals and meeting research, and it runs educational meetings for clinicians who treat cancer.

Can ASCO tell me what treatment to have?

No. ASCO does not see patients or review individual cases. Its guidelines inform your oncologist; your oncologist makes recommendations with you.

Why do I keep seeing ASCO mentioned in news stories?

Major cancer research is often first presented at ASCO meetings, so reporters quote the abstracts and presentations from those meetings.

Are ASCO guidelines the same as NCCN guidelines?

No. They are separate bodies with separate panels and separate documents. Both are widely used, and your team may cite either.

Is any of this free to read?

The American Cancer Society says the joint resource is free to the public on cancer.org. Professional journal content may have different access rules.

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 — Editorial review complete. This page completed Cancer Explained's editorial checks (sources, safety, plain language, duplication). It has not been reviewed by a physician or other healthcare professional.

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.
