There is a post here, most likely in a few places where topical application of cannabis oil, containing THC, was useful in suppressing melanomas.  I will poke around to see if I can find it but you should as well, if you’re interested.  It just a report on one person’s experience but it’s interesting reading.
You’re doing a great job of sorting these details out for Sunday!

I found the original post.  More recently there was another discussion of this but I don’t believe there were new information.
