By CancerTreatmentsResearch.com . Background: In the European countries Mebendazole can be found on the supermarket shelves. Mebendazole is an anthelmintic drug that has been used since the early 1970s to treat a range of parasitical worm infections, including threadworm, tapeworms, roundworms, and other nematode and trematode infections in humans and domestic animals ( Ref .). The drug is among those on the World Health Organization’s list (WHO) ( Ref .).

Abstract Fenbendazole (FBZ), a benzimidazole-class anthelmintic primarily used in veterinary medicine, has garnered attention for its potential anticancer properties. This review examines anecdotal reports and case studies regarding the use of fenbendazole, an anthelmintic agent traditionally used in veterinary medicine, as a potential anticancer treatment in humans. A compilation of more than 300 case reports across various cancer types, including breast, lung, colorectal, prostate, and pancreatic cancers, is analyzed to assess the validity of these claims.

Healthcare professionals should be consulted before considering fenbendazole as a treatment option.
