Our editorial standards

How we create & review content

Because cancer information can affect real health decisions, we aim for every article, guide, and e-card message to be accurate, safe, supportive, and easy to understand. We use AI tools to help draft and organize content. We then check medical wording against trusted sources. That check is not perfect, and it can miss mistakes.

Where we are today: Cancer Explained pages are meant to be editorially reviewed against cited sources from organizations such as NCI, NIH, CDC, and FDA. That work is still in progress, and many pages have not had a full source check yet. No page has been reviewed by a physician unless it names the reviewer. A page is labeled “Medically reviewed” only when a named, credentialed reviewer and a review date appear on that page. We are actively recruiting volunteer clinician reviewers.

How we work

How CancerExplained.org creates and reviews content

Every guide follows the same careful, seven-step path — from choosing a topic to keeping it up to date.

  1. Step 1

    Choose a helpful topic

    We pick topics patients and caregivers actually need — prevention, screening, treatment basics, side effects, caregiving, survivorship, exercise, nutrition, and mental health.

  2. Step 2

    Use trusted sources

    We rely on sources like the NCI, NIH, CDC, FDA, MedlinePlus, ASCO, NCCN patient guidelines, major hospitals, and peer-reviewed research.

  3. Step 3

    Create a plain-language draft

    Our team may use AI to help organize, simplify, or draft content. Every draft is then checked against its cited sources before publication.

  4. Step 4

    Check the facts

    Every medical claim is compared against trusted sources. We do not publish unsupported claims, miracle cures, or fear-based information.

  5. Step 5

    Review for safety

    Higher-risk topics — treatments, medications, prognosis, supplements, urgent symptoms, clinical trials, and end-of-life care — get extra review.

  6. Step 6

    Edit for clarity and compassion

    We make content easier to read, supportive, inclusive, and respectful. We avoid blame, shame, and confusing medical jargon.

  7. Step 7

    Publish and keep it updated

    Approved content includes review dates, source notes, related resources, and updates when medical guidance changes.

Content risk levels

The more a topic could affect someone’s health decisions, the more review it gets.

Low risk

General education, support, definitions, caregiving tips

Medium risk

Prevention, screening, treatment overviews, side effects, nutrition, exercise

High risk

Treatment decisions, prognosis, medications, supplements, clinical trials, urgent symptoms

This information is educational and is not a substitute for medical advice. Always talk with your doctor or care team about your own situation. Most pages are editorially reviewed against cited sources from organizations such as NCI, NIH, CDC, and FDA; a page is labeled “Medically reviewed” only when a named, credentialed reviewer and review date appear on it.

1. Content workflow overview

This is the path we aim for every page to follow from idea to publication and beyond:

  1. Topic idea
  2. Content planning
  3. Trusted source collection
  4. Risk level assigned
  5. AI-assisted or human drafting
  6. Source checking & fact review
  7. Plain-language editing
  8. Source-accuracy review
  9. Editorial review
  10. Disclaimer & safety wording check
  11. Publishing checklist
  12. Publication
  13. Ongoing review & updates

2. Content planning

We choose topics based on what patients, caregivers, and the public most often need help understanding — common questions, frequently searched terms, prevention and screening guidelines, treatment side effects, survivorship and caregiving needs, mental-health and emotional support, user feedback, and gaps in existing patient-friendly education.

High-impact topics come first — especially ones that help people make informed decisions or have better conversations with their care team. Before drafting, a topic is approved with a working title, target audience, the main question it answers, its content type, a risk level, the trusted sources to use, and where it will live on the site.

3. Source requirements

All factual medical claims must be supported by reputable sources. Whenever possible we rely on:

  • National Cancer Institute (NCI)
  • National Institutes of Health (NIH)
  • Centers for Disease Control and Prevention (CDC)
  • U.S. Food & Drug Administration (FDA)
  • American Cancer Society (ACS)
  • MedlinePlus
  • Peer-reviewed medical journals
  • American Society of Clinical Oncology (ASCO), on a small number of pages
  • NCCN Guidelines for Patients, on a small number of pages

We do not publish:

  • Unsupported medical claims
  • Miracle cures
  • Promises that a treatment, diet, or supplement will cure cancer
  • Fear-based language
  • Misleading survival claims
  • Unverified statistics
  • Advice to delay or avoid medical care
  • Anything that reads like a personal diagnosis or treatment plan
We don’t give individualized medical advice. Cancer decisions depend on your diagnosis, health, test results, and goals. Where it matters, our content reminds you to talk with your doctor, nurse, pharmacist, dietitian, or care team.

4. AI-assisted drafting rules

We may use AI tools to help create early drafts. AI-assisted content goes through editorial source review, where medical facts are compared with the original trusted sources. This is an editorial check, not a physician review, unless a named clinician reviewer appears on the page.

AI may help

  • Plain-language outlines and first drafts
  • Article summaries, FAQs, and checklists
  • Reading-level simplification
  • Questions to ask your care team
  • Supportive language suggestions

AI may never

  • Invent statistics, survival rates, or guidelines
  • Make treatment or medication recommendations
  • Create quotes, source names, or links
  • Approve content
  • Replace human medical review

If AI produces a claim we can’t verify against a trusted source, the claim is removed. Sensitive topics — prognosis, treatment decisions, mental health, supplements, clinical trials, urgent symptoms, medications, palliative and end-of-life care — receive extra review.

5. Plain-language editing

We write for real people — patients, caregivers, older adults, and anyone who is scared, overwhelmed, or newly diagnosed — aiming for about a 6th–8th grade reading level. That means simple, compassionate language, short sentences and sections, clear explanations of any medical terms, and “questions to ask your care team.” Our tone is calm, respectful, supportive, and honest without being frightening.

Instead of

“Patients should consult their oncology provider regarding contraindications and therapeutic decision-making.”

We write

“Ask your cancer care team if this treatment is safe for you and how it may fit into your care plan.”

6. Medical accuracy review & risk levels

We try to check pages for accuracy before publishing, and we re-check them over time. Because we’re a small nonprofit team, we assign each page a risk level so the most sensitive content gets the most attention. We have no clinician reviewer, so mistakes are possible. If you see one, please tell us.

Low risk

Examples: General education, support, definitions, caregiving tips, e-card messages.

Review: Editorial source review: checked against cited sources when medical facts appear.

Medium risk

Examples: Prevention, screening, treatment overviews, side effects, nutrition, exercise, survivorship basics.

Review: Editorial source review with trusted sources documented. No clinician has reviewed these pages unless a named reviewer appears on the page.

High risk

Examples: Treatment decisions, prognosis, medications, supplements, clinical trials, urgent symptoms, end-of-life care.

Review: We compare numbers, doses, thresholds, eligibility and when-to-get-help wording with the named trusted sources, and we cut or soften what a source does not support. We try to summarize sources without adding our own interpretation, and to include 'talk with your care team' and emergency guidance. This is an editorial source check. No clinician has reviewed these pages unless a named reviewer appears on the page. Errors can still get through.

7. Editorial, inclusivity & supportive language

After accuracy review, an editing pass checks clarity, grammar, tone, formatting, accessibility, reading level, internal links, and whether the page actually answers the reader’s question. Cancer information can be scary, so we keep it honest but never alarming — and we avoid fear, shame, and blame, taking extra care around weight, smoking, alcohol, diet, delayed screening, financial barriers, and access to care.

We write to be inclusive of people with different ages, cultures, reading levels, incomes, insurance situations, family structures, disabilities, and access to care. We never assume everyone has easy access to specialists, transportation, paid time off, healthy food, or strong support at home.

9. Publishing checklist

This is the checklist we aim to complete before a page is published. Automated publishing checks cover only some of these items, so a page can still go live with one missed:

  • Topic approved & audience identified
  • Trusted sources documented
  • Medical wording compared with sources
  • AI-generated text reviewed (if used)
  • Claims a source does not support removed or softened
  • Risk level assigned (Low / Medium / High)
  • Plain-language edit complete
  • Source check complete (clinician review added and named only if it happens)
  • Editorial review complete
  • Disclaimer & emergency language added where needed
  • “Talk with your care team” language included where appropriate
  • Last reviewed & updated dates added
  • Links tested & accessibility checked
  • SEO title & description written
  • Related resources added
  • Copyright / licensing checked
  • Final approval received

10. Ongoing maintenance

Cancer information changes, so we aim to review and update content on a schedule:

  • Low-risk content — up to 24 months between source checks
  • Medium-risk content — up to 12 months between source checks
  • High-risk content — up to 6 months between source checks
  • Guideline-based pages — reviewed whenever major guidelines change

Where they are recorded, a page shows its last reviewed and last updated dates. When screening, treatment, or safety guidelines change, we aim to find the affected pages, update them, re-check accuracy, and refresh the dates.

See something confusing or possibly incorrect? Please let us know so we can review it.

11. Team roles & approvals

These are roles in the process, not people on a payroll. Cancer Explained has no paid editorial staff and no clinician on staff; most of what follows is done by an AI-assisted system against published rules, with automated checks that can hold a publish, and with volunteer reviewers where we have them. We list the roles because the work still has to happen and someone or something has to be accountable for each part — not to suggest a newsroom.

Content creator

Proposes topics, gathers trusted sources, drafts content, and flags sensitive or high-risk topics.

AI drafting assistant

May help outline, simplify, and summarize — but never approves content, invents sources, or replaces medical review.

Editor

Improves clarity, tone, reading level, formatting, accessibility, internal links, and SEO.

Accuracy checking

Medical wording is compared with the sources cited on the page. The goal is to confirm the wording matches a source, not to prove the source is right or complete. Checks are recorded in editorial/source-check/ for the pages we have covered so far, and many pages have not been covered yet. The comparison is not sentence by sentence and can miss errors. Automated regression checks look for a list of known patterns, such as a drug dose without a safety note. They cannot catch every unsafe or wrong sentence. No clinician reviews these pages. A page carries a clinician's name only if a volunteer has reviewed it. NCI has not reviewed or endorsed this site.

Publishing checks

Before a page goes live, automated checks look at reading level, sources, some urgent-care wording patterns, drug doses, page code, and accessibility. If a check fails, the page is held. A passing result only means the listed patterns were not found. It does not mean the page is medically correct or safe.

Site owner

One person, who sets policy, decides what is published or held, and is accountable for everything here.

Scrutiny scales with risk. We aim to source-check every page, but that work is still in progress and is not the same as clinical review. Pages we class as high-risk — emergencies, dosing, anything where acting on a wrong sentence causes harm — go through the automated checks described above and are meant to be re-checked on a shorter cycle. No page waits for clinician review. If a volunteer clinician does review a page, the page names them; where that has not happened, the page says so rather than implying it has.

Clinicians, students, and patient advocates: we’re recruiting volunteer reviewers to strengthen the accuracy-review role above — about 1–2 hours a month, fully remote, with public credit on every page you review. See what reviewing involves and how to apply.

12. Our core principle

CancerExplained.org does not replace doctors, nurses, or cancer care teams. Our role is to explain trusted information clearly, compassionately, and responsibly — so patients and caregivers can better understand cancer and ask better questions.

When in doubt, we choose safety, accuracy, clarity, and compassion.
