Fenbendazole (FBZ) is a low-cost veterinary antiparasitic drug that has gained global attention as a potential anticancer therapy. Like ivermectin---another antiparasitic widely repurposed in research and clinical practice for its potent anti-tumor effects—fenbendazole appears to work far beyond its original veterinary use.
Preclinical studies show fenbendazole disrupts cancer cell survival through multiple pathways, but until now, human evidence has been scarce.
A newly published case series by Dr. William Makis et al in Case Reports in Oncology presents three remarkable patients with advanced, stage IV cancers (breast, prostate, and melanoma) who self-administered Fenbendazole outside conventional oncology protocols. All three achieved either complete or near-complete remission --- sustained for up to three years — without chemotherapy:
