FIG. 12: It has been established that histological variants of bladder cancer occur very frequently, making up about 25% of bladder cancer cases.[6,7] Since about 100,000 new cases of bladder cancer are diagnosed every year within the EU, and about 75% of those are NMI, then 25% of this number of cases is a clinically relevant number of patients.[7]
