"little to no care taken when appointments are made..."

A year ago I was told that I had bowl cancer and some 5 months later I had part of my bowl sergicaly removed. I then started a course of 6 months keematherapy which ended a month ago. I was sent for a ct scan 10 days ago and an appointment was made for today to see the specialist for the results (which is where it all went wrong). The original time was for 16.45 but I was to be there 1 hour before. At 10.30 this morning I got a phone call as they had cancellations so to bing it forward to 16.00. So me and my wife who had taken time off work to come with me, set off for the 45 min car jurney. I booked in at 14.45 at department 42 only to be told I had to have a blood test and given a ticket (strange as I was only going to get results of scan) but ok I joined the the group awaiting my number to be called. Then I heard my name called, went to reception and told to go to a separate waiting area to see the specialist, I asked "what about the blood test" she phone through and was told Ithat I don't need a blood test. Just before 17.00 we were joined in the consultation room by a doctor only to be told that they did not have the ct scan results and that an appointment would be made to come back in two weeks. From leaving home to getting back home was some 5 hours, the stress I have had awaiting the results of the scan, if the cancer had spread or if the treatment had been successful has been huge over the last month. Why ask me to come in early if they did not have the results, why send me for a blood test if I did not need one. Why did they not tell me earlier that they did not have the results? I now have to wait for two more weeks to think if I have cancer or not.
