Effects of delayed diagnosis on tumor size, stage and grade in bladder cancer.

In our study, it was shown that the tumor size increases as the duration of diagnosis delay increases and this increase causes an increase of 0.088 mm in the pathological size of the tumor in the 1-day delay period. Considering that tumor size changes the risk group of the disease in bladder tumors, and relatedly the follow-up and treatment process changes, we believe that these data will be valuable in the management of bladder cancer.
