I find the doctors speculating before you have had any tests quite unbelievable! 
There could be many many reasons for your symptoms. 
I'd try not to worry until you know what you are actually diagnosed with by a specialist. 
seems insane to assume anything at this point. 
A little knowledge is a dangerous thing. 
Good luck and stay positive worry will only make things feel so much worse.

Thank you so much for your response. I agree with you totally. My tests start at the end of the week. I really appreciate your reply 

oh my goodness my gp has done exactly the same and I have now gone into anxiety attack.  My gp diagnosed me over the phone and as we now have access to our consultations she has put me down as having pancreatic cancer pre any tests.  I have had an ultrasound and it is all normal
