What sort of prognosis?

I am reasonably sure that I have some sort of fairly advanced cancer.

For various reasons, I do not want to engage with doctors, and have accepted that my time I coming towards an end.

I never expected to be immortal, and have come to terms with the idea that this is how I will die.  It is what it is.

However, I'm unclear on what is likely to happen.

Can anyone point me to any good resources for reading on progression of cancer?

Please note that I'm seriously not interested in being told to go see a nurse or a doctor, so please respect my decision.  I am here only to seek info.
