Standard headline-and-introductory-paragraph bait and switch: “remember that breakthrough in human trials? Well, we've extended it to other forms of cancer… [3 paragraphs later] in mice.”
The article says it also works on dead human tissue. I don't know the significance of this, but it has been tested on something other than mice. I guess we can't make any conclusions on the adverse effects on a living human body, but it seems promising to me (not a scientist)
From the article:
> The molecule also killed cancer cells in human tissue that were gathered from patients who had their tumors removed
