Can a Common Deworming Drug for Pets Potentially Cure Cancer in Humans?
A simple deworming medication used for dogs and cats may hold the key to curing human cancer, according to recent studies and anecdotal reports. However, medical experts caution that much more research is needed before it can be endorsed as a safe and effective treatment.
Understanding Fenbendazole
Fenbendazole, sold under brand names like Panacur and Safe-Guard, is typically used to treat parasitic infections in animals such as roundworms, hookworms, tapeworms, and giardia.
Recent studies have suggested that this drug may also have anti-cancer properties in humans. In a video critique, Dr. John Campbell reviewed case studies from 2021, reporting that three patients with advanced cancer experienced tumor shrinkage after taking fenbendazole. He advocates for urgent regulatory review, emphasizing the urgency of finding new cancer treatments.
Emerging Research and Small Studies
Several scientific papers have been published recently highlighting the potential of fenbendazole in treating cancer. A 2020 study from Tennessee found that the drug slowed lung cancer growth in mice. Another study from 2023 concluded that fenbendazole “stands out” as a potential new cancer therapy after reviewing six human cases where tumors had reduced in size.

Popular on Social Media
There are numerous anecdotal reports on social media platforms like TikTok, YouTube, and X, where individuals claim thatfenbendazole has cured their cancer. The drug has become particularly popular on these platforms, with some users crediting it with entirely eliminating their tumors.

Medical Concerns and Risks
Despite the growing popularity, medical non-profits warn against using fenbendazole, pointing out that it lacks large-scale human clinical trials. Doctors also caution that the drug can pose serious risks, including intestinal necrosis, liver failure, and even potential promotion of cancer growth if not used carefully.
For instance, in South Korea, where the drug surge occurred in 2019, some patients suffered from intestinal necrosis. A 45-year-old British man also died from liver failure after taking fenbendazole to combat cancer.
How Fenbendazole Works
Fenbendazole primarily works by disrupting cell division in parasites by attacking microtubules, which are essential for cell division. Some researchers hypothesize that this mechanism could also apply to cancer cells, potentially halting or slowing the disease’s progression.

In animals, the drug is effective for two to three weeks, but its efficacy and safety for cancer treatment in humans remain unproven.
Comparative to Mebendazole
Fenbendazole belongs to the same class of medications as mebendazole, which is FDA-approved for human use. Mebendazole has shown some promise in treating cancer, including prolonging the lifespan of colon cancer patients.
However, a 2021 clinical trial using mebendazole found hyperprogression in five out of ten patients, suggesting that more research is needed to determine its safety and efficacy in cancer treatment.

Cost and Side Effects
Fenbendazole is relatively inexpensive, costing approximately $9 for a week’s supply. It is widely available as a liquid, powder, or paste for pets and can even be found on Amazon.
The side effects of fenbendazole are generally mild and may include stomach pain, bloating, gas, and diarrhea, which are far less severe than those of traditional chemotherapy.
The Future of Fenbendazole in Cancer Treatment
For fenbendazole to be approved for human use in cancer treatment, it must undergo extensive clinical trials. This process is lengthy and can cost millions of dollars.
Dr. Jason Williams, who experiments with alternative cancer treatments, stated that fenbendazole could be useful in specific cases but must be carefully tailored and closely monitored. He emphasized that it is a “double-edged sword” and warned against improper use.

Expert Opinions
Caroline Geraghty, a specialized cancer information nurse at Cancer Research UK, expressed skepticism about the claims, emphasizing there is insufficient evidence to support its use. She advised patients to discuss any new treatments with their doctors.
Dr. Campbell, while acknowledging the need for further research, remains optimistic about the potential of fenbendazole in treating cancer. He called for more aggressive research and regulatory attention.
Conclusion
The potential of fenbendazole in human cancer treatment is intriguing but remains largely unproven. While anecdotal evidence and small studies show promise, it is crucial to prioritize scientific rigor and patient safety. Medical experts stress the importance of clinical trials and caution against self-treatment with unproven alternatives.
For patients and their families, the best course of action is to consult with healthcare professionals before exploring any new treatments.
