Why Isn’t Heart Cancer a Thing?

Learnathon is a celebration of learning, of our free content here at SciShow and all of Complexly! We’re doing activities and videos and livestream Nov 9-20 at https://www.complexly.org/LEARNATHON/ Most people know someone who’s faced a cancer diagnosis. But ask yourself: Have you ever met anyone with /heart/ cancer? Probably not, because that type of cancer is very rare. And it’s taken scientists years to finally figure out why.
