    Video, everywhere it helps — and a clean-up pass across the library

    Forty-nine more short videos joined the library, and every one of our videos now has a single page where you can browse them all. Alongside that, a sweep of every published page fixed photo captions that were showing internal file names, repaired links that pointed nowhere, and corrected one symptom page that named the wrong temperature.

    • Forty-nine new one-minute videos cover the basics, screening, prevention, warning signs and the claims people most often search — all captioned, with no ads and no tracking.Watch all videos
    • Every video now lives on one browsable page, grouped by what you are trying to work out. Before this, you could only find one by landing on the right guide.Video libraryUnderstanding reports
    • Photographs across the library were showing internal catalogue names as their captions. Those are gone — a caption is now either real descriptive text or nothing at all.How we review content
    • Repaired links on more than fifty guides that pointed at pages which do not exist, so the next step in a guide now actually opens.Browse the library
    • Corrected a symptom page that gave 100.5°F as the fever to act on. The whole site now says 100.4°F (38°C), and an automated check covers our video captions too.Fever during chemotherapy

    Watch it explained: 30 short videos, captioned and checked

    Cancer Explained now has video. Thirty short explainers — how to read a pathology report, staging and TNM, biopsy results, frightening scan language, and the most-asked myth checks — play right on the relevant pages: self-hosted, captioned, no ads, no tracking. Every narration script was checked line by line against the site's sourced pages before rendering, the same standard our articles are held to.

    44 new guides and research explainers, checked line by line against federal sources

    A survey of the topics people encounter in cancer news led to 44 new pages: 38 plain-language guides — from reading an eosinophil count to caregiving during radiation — and 6 explainers on recent FDA approvals and major trial results. Every page was written from NCI, FDA, CDC and NIH sources, then independently fact-checked against those sources before publication.

    • New everyday-question guides: bone scans, colon polyps found at colonoscopy, 2D vs 3D mammograms, lung cancer in people who never smoked, skin cancer in people of color, and more.Browse all articles

    Honest dates on every page, and clearer nonprofit facts up front

    August's accuracy and safety passes changed thousands of pages, but the pages kept their older “last updated” dates. Every article now shows the date its content actually last changed, in English and Spanish. The homepage mission now states our IRS-recognized 501(c)(3) status plainly, and two practical tools that search engines could not find are now in our sitemap.

  5. August 20, 2026SafetyAccuracy

    One temperature, one rule: 100.4°F, on every page

    Two trusted sources give two different fever thresholds for chemotherapy — CDC says 100.4°F (38°C), while NCI prints 100.5°F beside the same Celsius figure. As of today every page on this site teaches the lower, safer number, an automated check keeps it that way, and our medicine guides now draw a clean line between what you handle at home and what only your treatment team runs.

    • Every page that names a fever threshold during cancer treatment now says 100.4°F (38°C), matching CDC — in English, Spanish, and every other language we publish. Where a page quotes NCI’s printed 100.5°F, it now also shows the conversion and tells you to act on the lower number. A new automated check blocks any future page from teaching the higher one.Fever during chemotherapy
    • Medicine guides now follow one rule. Amounts you handle at home — tablet strengths, missed-dose rules — stay on the page, tied to your own prescription label. Schedules only your treatment team runs — dose build-ups, infusion amounts, monitoring calendars — live where they belong: in your prescription, not on a web page that cannot know your kidneys, your liver, or your other medicines.Cancer medicines, explained
    • The money-saving guide now says plainly what was always true: tips like splitting tablets or partial refills are for supportive medicines, never for the cancer drug itself — with a direct route to real financial help for the drug that actually costs the most.Saving money on cancer medicines
    • If you suddenly cannot urinate at all, that is an emergency now — not after 24 hours. Two pages that used a 24-hour figure now separate acute retention, which cannot wait, from low urine output over a day, which is a different problem.Warning signs

    The melanoma vaccine result, explained in four parts, and a safety review of every translated page

    This week's news writing takes two stories people are arriving confused about and explains what the findings actually support — including four pages on the melanoma trial alone, because most of the confusion is in the difference between what it measured and what people think it measured. Alongside them, our pages in eleven other languages were reviewed against their English versions so that the when-to-get-help guidance reads the same in every one.

  7. August 19, 2026SafetyAccuracy

    An independent safety audit, and the source review completed

    We commissioned an outside review of the medical safety of this library, worked through every finding it raised, and published our reasoning where we disagreed. In the same week the source-review programme finished: every page on this site has now been checked line by line against the source it cites.

    • Every finding the audit raised was worked through and resolved. Where we disagreed with one, we recorded why, rather than changing a page to make a report come back clean.How we review
    • Patient pages point you at your own prescription label rather than at prescriber-facing dose tables. Where a page names a dose you might actually handle at home, the number to follow is the one on your own box.How we review
    • Urgent-symptom guidance was tightened across the library, and an automated check now blocks any future page that would place an emergency in a slower tier.Warning signs
    • The source-review programme is complete. All 2,656 remaining pages were reviewed, so every page here has been through a source check at least once.Our sources

    Survival figures brought up to the newest data release

    Survival statistics go out of date quietly — the number sits on the page long after it stops being the current one. Every page on the site that carries one has been refreshed against the latest release, and the sourcing behind each figure is now stated precisely.

    A faster site, and a front door that asks where you are

    Most people arrive here on a phone, often on a bad connection, often within a day of hearing news they did not want. The home page now starts with where you are rather than with what we have, and the pages themselves load faster.

    • The home page opens with a short set of routes — newly diagnosed, in treatment, caring for someone — instead of asking you to pick from a library.Home
    • Pages load noticeably faster on phones. We stopped preloading menus nobody had opened, dropped a compatibility bundle modern browsers do not need, and added a smaller image size for the phone screens that were downloading one too large.Home
    • The donate page was rebuilt: clearer about what a gift pays for, honest that we cannot price a single page, and it now mentions employer matching where you can see it.Donate

    One clear standard for when a symptom cannot wait

    Knowing whether something needs a phone call, a same-day appointment or an emergency room is one of the hardest things to judge from home. All 881 pages that tell a reader when to act now follow a single standard, matched to CDC and NCI wording, in English and in Spanish.

    • A fever during chemotherapy is a medical emergency. Every chemotherapy-related page now says so in the CDC’s own words, with the temperature that counts and what to do at any hour of the day or night.Fever during chemotherapy
    • Our highest-risk pages — emergencies, dosing, anything where acting on a single sentence matters most — were each re-read against the source they cite, and now sit on a shorter re-check cycle than the rest of the library.How we review
    • Guidance was calibrated in both directions. Some situations now escalate faster; others no longer send you to an emergency room for something that can safely wait for the clinic. Being wrong either way has a cost, and we tuned for both.Warning signs

    358 new plain-language guides on the questions people actually ask

    We looked at what patients, survivors and caregivers ask each other in public online communities, then checked every one of those questions against what we already had. Most were already covered. The ones that were not became this release: how to read the words on a scan or lab report, what specific side effects feel like and what to do about them, honest answers to circulating claims about food, household products and workplaces, and the practical machinery of insurance appeals, leave from work and disability benefits. Every page is written from a named federal source, at a grade 7 to 8 reading level.

    • Report and lab language, decoded one term at a time, so a result you read in a portal at 10pm makes sense before your next appointment.Tests and scans

    When Advanced Prostate Cancer Starts Moving Again

    Hunter Biden told the BBC that his father's prostate cancer had spread further into the bones and was painful. We added a page about what that phase actually involves: how progression is measured, what castration-resistant disease means, which treatments are approved once hormone therapy stops holding, and why reporting pain early makes the medicine work better.

    A Plain-English Pass Over the Whole Library

    No new section this time — a pass over what was already here. Hundreds of pages across the guides, the news archive and the answered questions were rewritten to read more plainly and to say something of their own rather than lean on a shared template. Every claim was traced back to a named source. The counts on the home page are now links, and the body diagram has been redrawn.

    • Cancer information has a way of drifting into the language of a medical journal. Sentences were shortened, long clauses split, and terms explained where they appear rather than assumed — so a page works for someone reading on a phone in a waiting room. The medicine did not change. The reading did.What the library holds
    • Pages that had been built from a shared outline were rewritten to fit their own subject, so each one reads as a page about its topic rather than a template filled in. Where two pages still carry the same sentence, it is because both need it — the note that no clinician has checked a page unless one is named, for instance.Where our information comes from
    • Every claim was traced back to a named, checkable source, and anything that could not be was corrected or cut. Attributions were made precise, ageing statistics refreshed, a Medicare eligibility answer brought in line with the current rule, and dead citations replaced with working federal ones.News and analysis
    • Two new automated checks now run over the whole library before anything goes live. One scores how hard each page is to read and blocks any page that lands above a ninth-grade reading level. The other looks across guides, news and questions at once for pages built from the same template. Neither is advisory: a failing check stops the publish.Answered questions
    • The body diagram you can use to find information by where a symptom is has been redrawn. It was a stick figure. It is now a proper body outline with the organs marked, and the keyboard highlight that had stopped appearing works again.Explore by part of the body
    • Smaller thing you may notice: the eight counts on the home page — articles, quiz questions, answered questions, glossary terms and the rest — are now clickable, so each one takes you straight to what it counts.Glossary

    Survival Numbers, Blood Cancers, and Two New Trackers

    About 112 new guides this sprint: survival and outlook pages for two dozen cancer types, blood cancer symptom and staging pages, and risk-factor pages rounding out the major cancers. Spanish grew by 110 real, human-checked translations and the last placeholder stubs are gone, the site now speaks Korean and Haitian Creole too, and there are two new tools for tracking your own care.

    • There was no survival or prognosis data anywhere on the site until now — one of the first things a newly diagnosed person searches for, and we had nothing. The new pages are careful about what the numbers mean and do not mean: a five-year relative survival rate describes a large group of people diagnosed years ago, not a prediction about you, and it is not the most current data available because treatments keep improving faster than the statistics can track.Lung cancer survival rates and what they really meanProstate cancer survival rates and what they really mean
    • Blood cancers stage differently from solid tumors, and that confuses people who go looking for the TNM system they have heard of elsewhere. CLL is staged with the Rai or Binet system, based on blood counts and a physical exam rather than imaging. Multiple myeloma uses the Revised International Staging System, built from a blood protein, albumin, an enzyme called LDH, and chromosome findings. New pages cover staging and symptoms across leukemia, lymphoma, and myeloma.CLL staging: the Rai and Binet systems explainedMultiple myeloma staging: the R-ISS systemLeukemia symptoms: what to watch for and when to get help
    • Risk-factor pages now exist for every major cancer, including several that were missing entirely — lung, breast, melanoma, leukemia, lymphoma, and more. They are careful to say the thing that gets lost in most risk-factor lists: having risk factors does not mean you will get cancer, not having any does not mean you will not, and no one caused their own cancer by having them.Lung cancer risk factors: smoking and beyondBreast cancer risk factors: what raises and lowers risk
    • Spanish stopped being mostly a facade. Roughly a thousand pages used to say, in effect, “not translated yet” and send you back to cancer.gov/español — those stubs are gone. In their place are 110 new full translations, written and checked in Spanish rather than run through once and left. The site also added Korean and Haitian Creole to its language list this sprint.Cancer Explained en españolLanguages
    • Two new tools for tracking what is happening to you over time, both private and kept on your device only. The symptom and side-effect diary logs severity over time, shows a simple trend for each one, watches for wording that sounds urgent as you type, and exports a clean summary for your next appointment. The next-steps tracker is a running list for after a diagnosis or a new result, so the follow-up scan nobody wrote down does not quietly fall through the cracks.Symptom & side effect diaryNext steps tracker
    • Behind the scenes, the site now keeps a record of what people search for and find nothing — not the words themselves unless they match the site's own vocabulary, just the pattern of a search that came up empty more than once. That list is becoming the actual queue for what to write next, instead of guessing.

    Dogs, Cancer, and What the Evidence Actually Shows

    Seven new guides on the questions people ask about dogs and cancer — whether dogs can smell it, whether therapy dogs help, what a service dog is allowed to do that a much-loved pet is not, and how to keep your own dog through treatment.

    • Dogs really can be trained to pick cancer samples out of a line-up in a laboratory. That is a real finding, and it is not the same as a test. Across 62 published studies, accuracy ranged from barely better than guessing to near-perfect, only six were run under conditions resembling real screening, and fewer than 200 dogs worldwide have been studied. No dog is an approved cancer test anywhere. The page says so plainly, because the risk with a story this charming is that somebody delays getting a lump checked.Can dogs smell cancer?
    • The largest trial of therapy dogs in childhood cancer found something nobody was looking for. Anxiety fell in the children who got dog visits — and fell just as much in the children who did not. What did change was the parents, whose stress dropped significantly. The visits appear to reach the people standing in the corridor that nobody is watching.Do therapy dogs actually help?
    • Service dogs, therapy dogs and emotional support animals are three different things in law, not three levels of the same thing, and the rules changed again this year. Airlines stopped having to carry emotional support animals in 2021. In May 2026 federal housing guidance moved to the same standard, so an untrained emotional support animal is no longer automatically accommodated in a rental. If you rent and rely on an animal, this one matters.Service dogs, therapy dogs and emotional support animalsCan I bring my dog to treatment?
    • Two practical guides for keeping your own dog. Almost nobody needs to rehome one. The adjustments are small — someone else picks up waste, the dog stays away from a line or a wound — with one exception worth knowing: federal testing found salmonella in 7.7% and listeria in 16.3% of raw pet food samples, and that risk lands on you. The harder problem is usually logistics, so the second guide is about who walks the dog on your worst day and how to ask before you are desperate.Keeping your dog safely during treatmentCaring for your dog while you are in treatment
    • Pet dogs get cancers that closely resemble ours, and they get them naturally rather than in a laboratory. A National Cancer Institute programme and a network of twenty veterinary centres run trials in dogs whose owners enrol them, which can answer questions faster than a human trial can.How dogs with cancer help human research
    • The site also gained new photographs this month for the parts of cancer that had none: palliative and hospice care, eating when nothing tastes right, and faith and chaplaincy. And the front page is now a much longer scroll, because almost everything the library holds was invisible from it.What the library holds

    Faith, Cancer, and What the Evidence Shows

    Nineteen new guides and thirty-four short answers on the sacraments in hospital, what religious teaching actually says about treatment decisions at the end of life, and what the research on prayer does and does not show. Six are also in Spanish.

    • Three beliefs cause most of the distress in this area, and all three are wrong. Anointing of the Sick is not only for the dying — the Catechism says it is fitting before a serious operation and may be repeated. Nobody is obliged to accept every treatment offered. And nobody is expected to refuse pain relief. The new pages quote the documents so you can check them yourself.Catholic faith and cancer
    • The hardest conversations get their own pages, with the texts in full: stopping treatment that is not helping, feeding tubes and IV fluids as death approaches, palliative sedation, assisted dying, fertility preservation before treatment, and what changes at a Catholic hospital.Stopping cancer treatmentFeeding tubes and IV fluids
    • We also looked at what the research actually found. Randomized trials of prayer for medical outcomes have not shown an effect, and no trial has tested cancer survival at all. Research on a person's own faith is a different question with different, more modest answers. We have kept the two apart, because collapsing them is how people end up being told their cancer progressed because they did not believe hard enough.Does prayer cure cancer?
    • Three companion guides cover the same ground for other traditions and for none: Jewish teaching, where the Orthodox, Conservative and Reform movements genuinely disagree about the end of life; Islamic teaching, where most jurists hold that seeking treatment is permitted rather than required; and spiritual care for people who are not religious, where the research measure was deliberately written so an atheist can complete it.Jewish teaching and cancer careIslamic teaching and cancer careSpiritual care when you are not religious

    Remembering Technoblade, and a Sharper Library

    A new piece about the Minecraft streamer Technoblade and the symptom he explained away, plus a round of work merging overlapping guides so every question has one clear, complete answer.

    • Technoblade was 23, had ten million subscribers, and thought the pain in his arm was from too much gaming. The swelling is what sent him to hospital. The page covers what sarcoma is, why some kinds are most common in young people, and how to tell an ache that needs looking at from one that does not.Remembering Technoblade and understanding sarcoma
    • Where several pages covered the same ground, we merged them into the single most complete guide — about 175 in this round — so a search brings you to the full answer instead of a partial one. If a page you had bookmarked now takes you somewhere else, that is why.
    • You can now see exactly where our information comes from. Our provenance page names the specific federal document behind each fact — the NCI page, the FDA label, the trial record — so you can open the original and read it yourself.Where our information comes from

    A Worksheet for Comparing Treatments

    The last tool we had listed as coming soon is now built: a printable worksheet for holding treatment options side by side, with the questions that fill it in.

    • Treatment options are usually explained one at a time, and by the time you get home you have half of one and a fragment of the other. The new worksheet gives each option a column and each thing worth knowing a row — including what happens if you wait, which is a real option people are rarely invited to weigh. It does not score or recommend anything, and you can print it blank and fill it in at the appointment.Treatment comparison worksheet
