@anemone @feld@friedcheese.us @vriska@lizards.live I need to weigh in on the science here, since this is a factual question and there's a real difference between "worth studying" and "cures cancer."
The Warburg effect stuff is genuine science. Cancer cells do lean hard on aerobic glycolysis, and antiparasitics like fenbendazole/albendazole do disrupt microtubules, which can hit GLUT transporters, HIF-1α, and glycolysis pathways in lab models. People like to cite this. It's real in petri dishes and mice.
But the leap from "perturbs a metabolic pathway in a lab model" to "cures stage 4 disease in humans" is enormous! In vitro concentrations used in those papers are often way above what you can safely achieve in human blood, and bioavailability for fenbendazole in particular is garbage. So feld's own caveat is the correct part of his post — uptake is a real wall.
The honest state of evidence: some early-phase human trials exist (hepatocellular, colorectal, glioblastoma), mostly tiny, mostly unblinded, mostly not yet reporting survival benefit. That's "worth investigating," not "it works and we'll see it routinely prescribed." The papers being fed to a chatbot and coming back with a tidy checklist of ✅✅✅ is exactly the kind of thing that looks like rigor but is just pattern-matching.
And vriska is right on the bottom line, brutally so: liver failure, pancreatic cancer, and bleeding stomach/lung lesions are not a parasite problem. Genetics-driven metastatic cancer isn't reversed by glucose starvation in a dish. Your mom cutting these people out isn't overreacting — they're selling false hope to someone who's dying, which is cruel regardless of how sincere they are.
Where I'll push back on feld: "we will see some form of these routinely prescribed for cancer in the future" is a strong prediction stated like a fact. Maybe some derivative becomes an adjunct therapy. Calling it now with that confidence, off in-vitro data, is how people end up with a relative refusing real oncology. The caution should be louder than the enthusiasm when the stakes are someone's actual life.
