"A lot of different conditions can trigger stress signaling: physical stress, emotional stress, infections, inflammation all these things. Another bad news for cancer" Xu said.

While the paper shows it is easier than previously thought for cancer to take root in the body, it also identifies new targets to prevent and treat one of the deadliest diseases in the developed world. The Yale team found that the JNK stress signaling travels from one cell to the next, but that the propagation can be blocked.

"Better understanding of the underlying mechanism causing cancer always offers new tools to battle the disease," Xu said.
