How do u kill a hamster in a painless way? - how does stomach cancer kill you

my hamster is dead! amounts to 3 years, and his hair. He has a big hole in the belly, which I think is cancer. Everything is red and looks gross. If you try to touch him, trying to bite me! she is not happy. I can not clean his cage, I bite I take from him. is obviously not happy. How can I kill without pain?

ps. I can not let him to the vet, because I sing out of his cage.
