You've heard the names. A friend mentioned them. A YouTube video swore by them. A Facebook group of 100,000 members says they cured stage IV cancer. And your oncologist either rolled their eyes or warned you against them.

So what is actually true about fenbendazole and ivermectin in cancer care?

What Is Interferon?

Interferons are natural proteins your body makes to help fight infections and abnormal cells—including cancer. They act like messengers, telling your immune system to wake up, attack, and clean up. There are three main types:

• Type I (IFN-α and IFN-β): These help stop cancer cells from growing and spreading.
• Type II (IFN-γ): This type activates immune cells to recognize and destroy cancer cells.
• Type III (IFN-λ): Mostly helps protect surfaces like your skin and gut, with growing interest in cancer research.

Interferons are so powerful that some cancer treatments use them directly or try to boost their effects.[i]
