I can sympathise - I had to wait 6 weeks between diagnosis and surgery. At my hospital all 3 of the consultants were on holiday within 2 weeks of each other, ridiculous timing. I was passed backwards and forwards between all 3 consultants who were all trying to pass the buck because they couldn't fit my case in! I saw a different consultant every week for 3 weeks!
I got extremely stressed out about it and was on the phone to my oncology nurse several times complaining and stating NHS guidelines on treatment. In the end they called my surgeon on holiday and finally gave me a surgery date. Because my surgeon wasn't experienced in laparscopic surgery he needed another more experienced surgeon to be present and that partly caused the delay.
It felt like the longest wait EVER but I can reassure you it did not affect my outcome at all. In fact after all my stressing they didn't find any residual cancer left and my loop treatment had removed it all. So I had spent a month and a half worrying about it growing and spreading for no reason. Be reassured that cervical cancer is very slow growing but I do understand your concerns and I could tell you not to worry but I know that will be pointless. Once you know more and have a treatment plan things will get easier though I promise.
In fact when my surgery day finally did come, it suddenly seemed to have been very quick and I didn't feel ready!
This is an excellent forum - there is loads of information and support on here and everyone is very friendly.
Hope your appointment on Thurs goes well.
