IN MICE!!!
Fingers crossed, but let's not get too far ahead of ourselves.
There have been thousands of experimental treatments which appeared to work on mice but did not work on humans. They did not work on mice either when trials were carefully repeated. That is just how these things go.
This treatment looks quite promising and worth the follow-up efforts. But as you say, "let's not get too far ahead of ourselves."
Cancer treatments have gotten way more effective over the last several decades because of slow, grinding research. Even so, a "magic bullet" that cures all types of cancer is a very complicated problem. If these scientists actually do have a lead on a workable solution, it will be too big to stop by any commercial rivals. So that should not be a concern.
I hope they found something that works.
Curin cancer in mice since 1980s. No so in people.
“IN MICE!!!”
At least they tested it on mice first—with vaccines we test it on people first.
