A Veterinary Drug, Fenbendazole, May Be an Effective Cancer Treatment
In a 2021 Facebook post, Joe Tippens described his success using a regimen of fenbendazole and other natural supplements to treat his pancreatic cancer. This protocol, also known as the “Joe Tippens fenbendazole cancer protocol” or the “Fenbendazole Cancer Treatment,” suggests patients take 222 mg of fenbendazole per day, seven days a week as oral granules or a liquid suspension. The medication is an antiparasitic drug used to treat roundworm and hookworm infections, and it works by cutting off the parasites’ supply of nutrients by blocking their cell walls. Scientists are now investigating whether fenbendazole can prevent or treat human cancer cells by the same mechanism.
Researchers have discovered that fenbendazole—also known as mebendazole—can reduce cancer cell growth in cultured cells and slow down the spread of tumors in mice. But there’s insufficient evidence from randomized clinical trials that the drug can cure cancer in people.
The research suggests fenbendazole stops cancer cells from growing by inhibiting the formation of microtubules, which provide structure for all body cells. Normal body cells use a protein called tau to form the microtubules; but in cancer cells, a different protein, cyclin B1, forms them. Fenbendazole targets cyclin B1 and depolymerizes the microtubules of both normal and cancer cells, causing them to break apart and die. This may be why the drug is so effective in killing cancer cells, while hardly affecting healthy ones. fenbendazole for cancer
