Colon Cancer & Secondary Liver Cancer- Advice Needed Ple

Hello. I despertaly need advice! Yesterday my dad was finally diagnosed with bowel cancer (18cm up)and after a ct scan they know it is in the liver and possibly the lung/s. Around june he was diagnosed as anemic after complaining of fatigue and bowel changes. He had a colonoscopy tues 16th aug, a ct scan wed 24th, saw a specialist in upper gastrointestinal surgery and laparoscopic surgery yesterday who gave a too brief dukes 4 diagnosis. The surgeon was quite patronising and not very repsonsive.We have now been told to wait until next wed 31st for an mri scan and to see a specialist on 1st sept. The whole process has been hindered by a disinterested gp and now we're not fully confident we're recieving the best care. This seems a very long time to wait for diagnosis and treatment. Does anyone have suggestions about investigating specialists or changing a family dr/gp at such a crucial time? Will it delay treatment? Can anyone reccomend specialists in uk (specifically tyne and wear/ newcastle)? Should we consider paying for private treatment? Does anyone have experience of dukes stage 4 treatment , management?What is life expectancy? 1, 2 ,3 years?Less? Thank you so much for reading this. Replies to this or hac500@ya hoo.Co.Uk
