Bloop - the information about stage 4 being a death sentence is just wrong. There are a bunch of us stage 4 people here on the boards, and there is a lot of outdated information on the web. PUt those two things together and the rational for the death rate statement goes away.
Put your trust in what the people here tell you. 4 is just a number. You are an individual, and not a statistic. I bet you are nothing like the group that the statistics were drawn from. If you are not, then why should you be thinking about something that happened to a bunch of people you are nothing like? You can take that to the bank. It's true.
