Current Events > Can Cancer kill you from one day to another without any warning?

(+) Yeah! (+)

Im sorry if the question sounds a bit noobish, but i have no idea how cancer works.

I have a friend's uncle whose Cancer was detected on January 27th, supposed to be on early stages. The were supposed to travel yesterday somewhere so they could treat him yesterday, i saw a facebook post of someone related to him saying he died today.

While i dont have much info about it, it seems he was still doing his daily activities in an ok way, so im pretty sure they wouldnt have taken the trip had he been in a poor state.

Does that means he probably died during the trip or from one momento to another? Is this possible with cancer? I had no idea it could literally take you away from 1 hour to another..

Not that fast but they can diagnose you during the late stages and there would be nothing doctors can do about it.
