Hello Sean9,

                    l can really understand your worries,but do not lose sight of the fact that it is really early days and that even with spread to the liver ,successful treatment may well be possible.You may well face a very long journey in front of you,so best to try and stay on level ground and pace yourself,depending on facts as they become apparent,rather than jumping to fearful scenarios.l say this as one who is 7 yrs on from stage 4 colon cancer with subsequent spread to liver with 60% excised,and living life to the full.

                                                                                                                                                  l hope it goes well for your father and he has a successful outcome,

                                                                                         David
