Tonsil / throat cancer anxiety - questions

Hi there , 

6 weeks ago I noticed a lump on the back of my throat , on the back wall and a bigger right tonsil . I've also got a feeling like something catching on the tonsil and had earache . I suffer with tonsil stones but can't see them or get them out .
I was put on a two week referral , had a camera up my nose which they said looked fine , had blood tests , again fine and they checked my neck , no lumps . I also had a chest X-ray , also fine .
The ent dr said that the throat lump could be a mucus retention cyst so next they sent me for an mri of the neck with contrast . I presume to check for anything sinister? 

The secretary rang me yesterday to say that the mri was discussed at an MDT meeting and i was to be informed that it was fine . 
however they still want to see me again face to face. 

i suffer with huge health anxiety as you can probably tell that I need to address but can anyone tell me why they want to see me ? Could the mri scan have missed anything? What will happen next? Would an mri scan with contrast have picked up any Tumors or cancer in my throat? 

thanks to anyone that has read , I'm so worried xxx
