Key fact

ASTRO is the American Society for Radiation Oncology, the professional society for the field.

The short answer

ASTRO is the professional society for radiation oncology. It creates patient education materials including brochures and videos in English and Spanish, meant to help clinicians explain radiation therapy and help patients make treatment decisions. It also runs APEx, an accreditation program aimed at patient safety in radiation oncology practices.

  • ASTRO is the American Society for Radiation Oncology, the professional society for the field.

  • It offers patient videos and brochures available in English and Spanish.

  • Those materials are made so members and referring physicians can explain radiation therapy and help patients with treatment decisions.

  • ASTRO runs APEx, which it lists among its products to ensure patient safety.

The full explanation.

Where the brochure came from

If you are having radiation, someone probably handed you a folded pamphlet. It had a diagram of a machine on it and a page about skin care.

There is a decent chance ASTRO made it, or made the template it came from.

ASTRO is the American Society for Radiation Oncology. It is the professional society for the doctors, physicists, dosimetrists, therapists and nurses who work in radiation oncology. Like most professional societies, its main audience is its own members. But a slice of what it produces is aimed squarely at you.

The patient materials

ASTRO says it has created educational materials such as brochures, videos and PowerPoints to enable its members and referring physicians to explain radiation therapy to patients while assisting them in their treatment decisions. It also says patient videos and brochures are available in English and Spanish.

Read that sentence carefully, because the design tells you how to use them. These are conversation tools. They were built to be used by a clinician sitting next to a patient, not as a substitute for that conversation.

That is genuinely good news if you are the kind of person who freezes in appointments. A shared piece of paper gives you something to point at.

What ASTRO can do for you today

A few concrete things.

You can ask your radiation oncology team for the patient brochure or video for your treatment. If English is not the language you read most comfortably, ask whether the Spanish version is available. Many centers have both on hand and simply hand out whichever is on top of the pile.

You can watch a video before your first session. Radiation is a strange experience the first time. You lie still, alone, in a large room, while a machine moves. Knowing in advance that the machine will circle you and that you will not feel the beam takes some of the fear out of it.

You can use the material to build questions. Read the brochure, mark two things you did not understand, and bring it. That is exactly the use it was designed for.

And you can ask about accreditation. ASTRO lists APEx among the products it offers to ensure patient safety. Asking your center whether it holds APEx accreditation, or another accreditation for radiation oncology, is a reasonable question. So is asking who checks your treatment plan before it is delivered, which is the practical safety question underneath all accreditation.

What ASTRO cannot do for you

ASTRO does not treat patients. There is no ASTRO clinic and no ASTRO physician who can look at your plan.

It cannot tell you whether radiation is the right choice for your cancer, how many sessions you should have, or what dose is appropriate. Those numbers come from your own radiation oncologist working from your imaging, your pathology and your anatomy. Two people with the same diagnosis can have very different plans for reasons that make complete sense.

It cannot manage your side effects. A brochure can tell you that skin changes are common. It cannot tell you whether the patch on your chest this week needs to be seen. Only your team can, and that is a call worth making rather than a page worth rereading.

It does not handle billing, insurance appeals, transport to daily treatment or lodging. Those are real problems during a six-week course of radiation, and other organizations exist for them.

And a general brochure will not always match your center's routine. Machines, scheduling and skin care instructions vary. When the pamphlet and your nurse disagree, follow your nurse.

A word about accreditation and safety

People sometimes go looking for accreditation information after reading something frightening about a radiation error. That instinct is understandable.

Here is the calmer framing. Radiation oncology is one of the most heavily checked areas in medicine. A plan is built, verified by physics, and confirmed against your position at every session. Accreditation programs exist to make sure those checks are routine rather than heroic.

If you want reassurance, you do not need to research organizations. Ask in the room. Who made my plan? Who checked it? How do you confirm I am in the right position each day? Any radiation team will be glad to answer, because the answer is something they are proud of.

Using it lightly

You do not need to become an expert on radiation oncology to get good radiation care. Most of what helps is small and human.

Take the brochure. Watch the video once. Write down the number you call after hours. Tell someone when your skin starts to hurt instead of waiting until the last week.

The materials ASTRO makes are there to make those small things easier, and that is the whole job they are meant to do.

Common questions

Does ASTRO have free material I can read about radiation therapy?

Yes. ASTRO describes patient videos and brochures available in English and Spanish, created so clinicians can explain radiation therapy to patients and help them with treatment decisions.

Is anything available in Spanish?

ASTRO says its patient videos and brochures are available in English and Spanish.

What is APEx?

APEx is an ASTRO program listed among its products to ensure patient safety in radiation oncology. If it matters to you, ask your center directly whether it holds APEx accreditation.

Can ASTRO tell me whether radiation is right for me?

No. ASTRO is a professional society and does not see patients. That decision belongs to you and your radiation oncologist.

Who normally gives me ASTRO's materials?

Often your care team. ASTRO says the brochures, videos and slide sets are made to help its members and referring physicians explain radiation therapy.

Is ASTRO the same as ACR?

No. They are separate organizations, though both work in areas involving radiation. ACR accredits imaging and also has a radiation oncology accreditation program; ASTRO is the radiation oncology society and runs APEx.

Should I ask whether my radiation center is accredited?

It is a fair question, and worth asking alongside questions about who plans your treatment and how the plan is checked.

How this page was created

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.
