As Cynthia already said, yes.
In my case, I was treated for multiple UTIs during a year before I wound up getting referred to a urologist who found the CIS.
They probably were true UTIs though because they were accompanied by the burning pain and frequency. That is to say more frequency than I already had due to enlarged and occasionally enflamed prostate.
People do have blood in the urine with infections w/o having cancer though.
