No, there haven’t.
There have been a lot of posts CLAIMING that cancers have been cured after the US left who. Especially on twitter. But if you look into the claims - the news is real. Just a year old. Or more.
PLEASE verify claims like this guys
Hey just so we’re clear there have been so far at least five cancers with demonstrable cures ever since the US left the WHO. That Big Pharma conspiracy was true too.
