Thanks for the reply can I ask how long you husband was given and is he going through any treatment ?

he wasnt given any time as they cant tell they couldnt say in case they got it wrong just a matter of time he had chemo for a while but hasnt had anymore as it didnt do any good, had some radiotherhpy a few weeks back which should have burnt off some the cancer cells, but wont know if this has happened until we see specialst hope this helps
