This is a repost of a 'guest', who posted their query in the wrong thread, but I'm willing to forgive them because English is not their first language. So i will post their query which is in Spanish and then I'll try to google translate it.

I'm looking for a fic where Spike becomes the Shanshu. Once Spike Shanshu he gets cancer, because when he was human he had cancer. The scoobies find out he's dying of cancer.
