PET Scan results

I had a PET Scan carried out on 24th July this year and was telephoned by my Consultant Urologist on 22nd Sept, to be informed that my Cystectomy for the 24th would not be going ahead as planned. This was  because there had been a delay in the Scan results coming back and there was something on my Sacrum now. I now need yet another MRI Scan to be carried out in order to confirm. This is building another delay into my treatment in addition to the 2 months caused by the result initial delay. Is there anything I can do?
