Interesting question. I'd say yes, because when you look at the lower demon moon Rui's story, as a human he had a weak and futile body, likely the result of some disease, and becoming a demon helped him. This can also be seen from Yushiro, who had a horrible disease that would likely kill him if he stayed a human, but was saved when he was turned into a demon by Tamayo. It is possible that, similar to Deadpool's regenerative ability, the cells just regenerate faster than they can be killed.

TL;DR: Yes
