I have had pain in my bladder for a while. My urine analysis (3 of them) have been off and now we did a cystoscopy and there was no tumor but a very clear area at the bottom of the bladder that was covered in red spots. I am scheduled to have another cystoscopy on Monday (this time full anesthesia) to get a biopsy. No tumor just that area of red spots which are very discernable. Can this be cancer?
