"If any human cancers ever became contagious, we'd be screwed as a species."
Only screwed in as much as it would be a bad idea to go and rub open wounds up against other people's fungating tumours. The thought of that doesn't appeal to me, and I suspect it wouldn't to many others either.
It has been known for a while that this disease is a transmissable cancer; I believe this new research has found that it is a certain type of cancer, where the telomeres* do not shorten on cell division, thus meaning that the cell line can continue indefinitely.
*Note, telomere, not telemore or telomore, from the Greek telos, 'the end' and moros 'the part', literally 'the end part'
