Roger Rasmussen’s Cancer Journey with Fenbendazole

When Roger Rasmussen received his prostate cancer diagnosis in December 2019, he had no idea that a chance conversation about "dog dewormer" would change his life. Sitting in a holistic doctor’s waiting room (a visit he only agreed to because a friend insisted), Roger overheard a woman discussing an unconventional cancer treatment.

“She mentioned dog dewormer and cancer,” Roger recalls in our recent podcast conversation. “My natural reaction was like, ‘Where am I? This is the Twilight Zone—get me out of here!’”

But that night, curiosity led him to research Joe Tippens’ blog (mycancerstory.rocks), where he discovered Fenbendazole—an anti-parasitic medication commonly used for pets that showed promising effects against cancer.

A COVID Silver Lining

As Roger considered his options—surgery, radiation, or chemotherapy—the world shut down due to COVID-19. His scheduled prostate removal in April 2020 was pushed to summer. While most of us curse the pandemic’s timing, Roger calls it his lifesaver.

“COVID gave me more time to explore Fenbendazole, to try it out. That’s why I was happy for that delay,” he explains.

During this unexpected window, Roger began taking Fenbendazole along with supplements recommended in Joe Tippens’ protocol. When his PSA levels started dropping and a self-arranged MRI showed his tumors shrinking, he made the bold decision to cancel his surgery entirely.

The Courage to Trust Yourself

What stands out in Roger’s story isn’t just that he found an unconventional path—it’s that he had the courage to walk it. Against medical opinion, Roger continued monitoring his cancer with privately-paid MRIs while maintaining his protocol.

“I got nine MRIs over the next year and a half,” he shares. “I wanted to check every three or four months because I was in no man’s land doing my own thing.”

His persistence paid off. The cancer continued to respond, and eventually, he stopped the protocol altogether in 2022. Remarkably, his PSA levels have continued to improve even after discontinuing treatment.

A Brother’s Confirmation

If Roger’s story seems like an outlier, consider this: when his brother received the same diagnosis about a year ago, Roger shared his protocol. Within three months on a daily regimen of Fenbendazole and Ivermectin, his brother’s follow-up MRI showed all tumors had disappeared.

Even Roger’s skeptical doctor, who had once dismissed the approach as “voodoo medicine,” could only call the results “remarkable.”

Beyond Anecdotes: The Science

What makes Roger’s contribution particularly valuable is his dedication to understanding the scientific foundation behind these treatments. His new book, “Finding Fenbendazole,” compiles 59 research studies examining how these compounds affect cancer cells.

“I wanted to create a guidebook that’s not just, ‘Hey, this is dog dewormer, use it for cancer,’” Roger explains. “It’s more than that. Here’s some studies that support why this is working.”

Roger approaches the subject with humility, never claiming to have all the answers. Instead, he offers what he’s learned from his journey and the growing body of research that suggests these overlooked compounds may have significant anti-cancer properties.

The Protocol Evolution

The approach to using these compounds has evolved since Joe Tippens first shared his story. Roger explains that taking Fenbendazole daily (rather than the original 3-days-on, 4-days-off protocol) and adding Ivermectin has shown better results in many cases.

“When you do three days on and four days off, you’re giving cancer a four-day weekend to do its thing,” Roger points out.

He also emphasizes the importance of taking these compounds with fat for absorption and monitoring liver function with regular blood tests—practical advice that can make a significant difference in effectiveness.

An Asymmetric Bet

What makes this approach worth considering? As we discussed in the podcast, it represents what we call an “asymmetric bet”—where the potential upside far outweighs the downside risk.

“It’s a relatively low investment, low-risk alternative,” Roger notes. “And the payoff is huge.”

This doesn’t mean abandoning conventional medicine or diving blindly into alternatives. It means considering options that, when the evidence and circumstances align, might offer hope where standard treatments have plateaued.

Finding Your Own Path

Roger’s story reminds us that sometimes the most courageous act isn’t fighting against a system but quietly charting your own course alongside it. He didn’t storm out of his doctor’s office or burn bridges—he simply added another strategy to his healing journey.

“I kept a lid on it,” he admits. “I thought, well, I’m going to try this, and if it works, I’ll tell people. If it doesn’t, I’m not going to let them know how crazy I really am.”

But perhaps the most valuable part of Roger’s story isn’t the specific protocol—it’s the reminder that sometimes healing requires us to trust our intuition, do our research, and have the courage to explore paths less traveled.
