Hi

My sister was diagnosed with ulcerative colitis 26 years ago and has been living with a colostomy bag ever since. She was then re-diagnosed with Crohn's several months ago in the remaining part of her colon but she was also having lots of problems with pain etc in her bladder.  In May this year she had a bladder biopsy to check for cancer but this was clear.  She then was admitted to hospital in September to have the remaining part of her colon removec but the operation  was postponed for a week because there were no ICU beds available. When they did eventually operate they found they could not perform the planned surgery as she had bowel cancer that had spread to her bladder. This has now been staged at stage 4. 

Is there any way of finding out how it was left to get this serious before anything is being done about it when she has had numerous scans and biopsies to investigate it?

Thank you
