Answer 1

Imagine a wet dog is like cancer, once it enters the house you have very little time where you can grab it and get it out the house before everything gets wet. but once it shakes it self dry removing it from the house will do little for the room, but it will prevent it from making the other rooms dirty. sometimes they will cut off the whole body part or room to prevent it from infecting other parts/room
