My Mum had an incomplete colonoscopy over 2 weeks ago and as they were not able to get all the way around with the camera, they wanted her to have a CT colonoscopy to rule out bowel cancer. They said at the timewithin 2 weeks but since then 6 weeks has been mentioned. She did chase it last week but they just told her the ball is rolling.

I'm just wondering what the normal waiting times are and whether she should be chasing this? It's 4.5 weeks since she first saw her GP and we still don't know whats going on. 

Thanks
