Other animals do get heart cancer, which is fascinating. It's still very uncommon compared to other cancers, but not virtually absent as it is in people.

Uhh thanks for sharing I guess? The third paragraph just nukes the idea of divulging anything, it's obviously written entirely for specialists in the field (chromatin remodeling? the Nesprin-2 protein? mechanotransduction?). What I'm trying to say is no layperson would walk away from this article with a slight idea of why there's no cancer in the heart.
