Panic stricken - referred to a consultant

. I've had tests for bowel/lung cancer - bloods, chest xray & cat scan. I have an appt. tomorrow with my GP & was hoping she'd say nothing showed up. But, I've just had a call from the hospital saying my GP has referred me to a consultant (no examination) he just wants to see me. It's on Saturday. WHY? I'm panic stricken. Has anyone else had this happen to them? The consultant doesn't want to see me for no reason so what can it be as it isn't any tests? It can only be bad bews surely?

Please can someone give me some clue about this?

Thanks
