Sure, there's a few. But 3 rodent studies isn't exactly enough evidence for a layperson to worry about, either. It's not even much of a signal for scientists in that area of research.

Ivermectin is pretty safe for people to use regardless of whether or not they have parasites, so sure, do the human RCTs. Maybe we'll get lucky and have another tool in our anti-cancer toolbox.

But trying to extrapolate out that it's reasonable for people to take it for cancer based on the current evidence is premature, at best.
