Hello Debzrich, so sorry about your dad.  Your dad's illness has metastatised, which means that it has spread beyond the original cancer site.  It has gone beyond the point where your dad can be cured.  Is there a possibility that you can speak to your dad's consultant without your dad being there?  The consultant will be able to tell you what the prognosis is likely to be (approximately how long your dad has got).  I am so very sorry.  My thoughts are with you, your dad and your family.
