Claim: Did many cancers have cures discovered after the US left the WHO?
Claims like these are everywhere on X and Bluesky, and strangely enough not so much any other media. Let's figure out if cancer really was cured after the US (vaguely implied to have been suppressing the cure) left the WHO in January 2026
On January 27th Mariano Barbacid claimed to have cured pancreatic cancer in mice, but his study on this was published in December, before the US left the World Health Organization, and it was only in January that he asked for funding to pursue his cure (this El Pais article is one of the few sources digging into the claim and not citing the same clickbait, so it's my main source here)
Similar events occurred in 2011, when he claimed to have cured lung cancer, in mice, and immediately asked for funding. He was rebuked by the Spanish Ministry of Science for announcing results in mice as relevant to humans. The linked article includes scientists criticizing him for going to the press to call it a "cure for cancer" instead of a promising step. Indeed, a University of Pennsylvania team led by Ben Stanger discovered a similar therapy earlier in 2025 without the same amount of media attention.
All in all it paints a picture of something that happens very routinely, even before to the same scientist: a promising study of a potential treatment for cancer in mice that was blown up by the media into a imminent cure for cancer in humans. Regardless, it wasn't being conspiratorially suppressed until the US left WHO, because the study was announced beforehand, and an American team did similar research in 2025.
This is referring to South Korean scientists discovering a potential way to reverse colon cancer. Something first reported in 2024, well before the US left WHO.
This was apparently cured by Chinese scientists; this is a reference to Peixuan Guo, who found an RNA therapy to remove cancer...in mice. This is, once again, a promising treatment in mice that's yet to be tested in humans that the media seized upon.
As an aside, part of the reason conspiratorial claims that They are hiding the "cure for cancer" is because of sensationalist media coverage highlighting potential treatments way before they're ready for primetime. These stories happen all the time, and eventually either it becomes a treatment (not cure) we use or is discarded, but all the public sees is a stream of Cures for Cancer that seemingly vanish.
As for whether this was suppressed until the United States until they left WHO: Peixuan Guo conducted this research at...Ohio State University.
This is a reference to Eva Ramón Gallegos, who eradicated HPV in 29 women. In 2019. This is real research, but an older story that was brought up and framed as something new in order to cash in on the viral narrative after the pancreatic cancer claim took off.
This refers to a study in Vietnam announced last year - again, before the US' departure from WHO was complete. But it is being inaccurately reported; it's not a cure on "blood cancers", it's a treatment using cell therapy that helped one patient with acute childhood leukemia. This is good and promising, but was never claimed to be a "cure for cancer" until the press got hold of it and twisted it to fit a current narrative
Anyway let's look at the ones in the other tweet
I cannot find out what this is a reference to. I just find crank stories from the MAHA sphere
I think this may be a reference to the colorectal cancer cure. Otherwise I just get a bunch of stories about ivermectin
This seems to be the same story as the one about colon cancer; otherwise I'm not finding a source story they're responding to
Yeah, for all these I'm just finding nothing but tweets insisting stomach cancer was "cured". Like, you would think that EVERY CANCER being cured would spawn a few news stories, at least, but no! It's just tweets claiming it was cured with no further information
"Cancer cured" and ivermectin posts
"Cancer cured" and ivermectin posts
I found this study from 2025 for a treatment eliminating it in patients, but again, it's just "cancer cured" and ivermectin posts, with no citations of it, so I don't know if that spawned this
"Cancer cured" and ivermectin posts
Five real cancer treatments, none of which are cancer cures as far as we know yet, that went viral. The only one that was new was the colorectal cancer one, which was discovered in the United States. The others are largely from 2024 or 2025 and one as old as 2019.
Eight random ones thrown in without any clear source story. You would think the lack of any news stories about EVERY CANCER being cured would make some people get sus, but no
Let's just state what should be obvious: these types of stories happen all the time, and do not indicate a cure for cancer "being suppressed".
The US retreating from the World Health Organization and from medical research don't represent a win, of science finally getting out under the boot of repression, but a tremendous loss. The United States was the leader in clinical trials, number one in life sciences research. Or it was, until Trump slashed their funding for no reason. American medical researchers weren't greedy fatcats who were making cures for cancer just to hide them forever; they were responsible for much of the world's research and medical treatment! It should be obvious that the world is further away from a cure to any cancer after some of its biggest research institutions were decimated, and yet
