Waiting for bladder cancer diagnosis

hi

This is the first time I have posted on the forum...i have recently had a scan that showed and abnormality in in my bladder and am now waiting for a cystoscopy... does this mean I have bladder cancer ?

My symptoms are passing urine a lot .. burping passing stools a lot.. pain in lower left side and upper and lower abdomen ...I was convinced I had IBS! But my doctor wanted to be cautious so referred me to a urologist ..I am in shock re this ... any advice would be greatly appreciated ?
