Kidney C

After CT scan for liver cirrhosis they found an area on my kidney they believe is cancer, having another scan next week to check it has not spread.  However I have also been referred on a two-week cancer plan to the MDT and a Urologist appointment 2 days after scan.  If they only believed it may be cancer why all of the urgent referrals.  I have dealt with 5 skin cancers but this one scares me as only found after cirrhosis confirmation.  I was referred as found autoimmune cells in a blood test, which I then hear from my consultant were also found in an older test but not acted upon, now worried the cancer may have been there for longer and could have perhaps been avoided, or dealt with sooner if it has in fact spread  I realise this is so much more minor than some of the other posts here, so sorry.
