"waiting for appointments"

I went to my GP with a painful lump and was referred for an ultrasound. After two months of waiting I eventually had my scan and was told I have a tumour which they believe to be benign but would require a consultant to deal with it as the GP ‘did not know’ how they get treated. 3 months later I received an appointment with a consultant only for this to be cancelled and rescheduled for a further three weeks down the line (causing me to reschedule time taken off work which had been arranged for the appointment). The consultant has referred me for a CT scan, within days I received a letter from Radiology dept saying I has to get a blood test within 10 days or they would cancel the referral, I had the test within 2 days.

I then received a letter scheduling an appointment with the consultant to get the results of the scan but have not received an appointment for the scan. Upon phoning the consultant’s secretary I was informed that the scan is still listed as pending as Radiology have yet to assign me an appointment, 5 weeks later. With less than a month until I am due to get the results, this does not leave much time for NHS Lanarkshire to schedule the scan with the appropriate 7 days notice as per their guidelines and have the results ready in time for my follow up appointment. Thus I fear that this will once again end up having to be rescheduled, leading to more disturbances with my work as I have arranged the time off for this appointment.

I have been in daily pain for months and 6 months after initially seeing my GP about this problem, I am still looking for answers.

Can someone please tell me how long I should have to wait from a consultant’s referral to getting a CT scan and how they can schedule results appointments with no idea of when the scan will eventually take place?
