Metformin and older antihypertensive med kills cancer

What I find especially encouraging about that study is that:

A) It's repurposing existing drugs with long histories, so toxicities & SE are well known and approval for use, if warranted by results, should be pretty much a slam dunk.

Both drugs are off-patent, so should be cost-effective

C) Both drugs are likely to actually be relatively benign or even good for women rather than otherwise

It will be interesting to watch this and see how it plays out.
