So sorry, Mary, that you now have this to worry about. But, as you are aware, there are many causes of hematuria and only one of them is bladder cancer. A problem with urine cytology, and this includes the FISH test, is that these tests tend to be too sensitive. That is, they often indicate positive results, ie...cancerous cells, when there aren't really any there. Cells can be "smashed" or distorted during the procedures. So these tests are used WITH other things, such as cystoscopy,
I assume that you meant that the test in three months is a cystoscopy? That would be the usual protocol. You have recently had one and there wouldn't be any point in doing another so soon. In another three months it is possible that if there is a problem it might show up by then. Your urologist is absolutely correct in doing this, so you are obviously in good hands.
I posted a link to a timely article on the possible causes of cancer under the Forum heading "Articles of Interest" under the topic of the Latest Issue of CURE. You may find this interesting reading! I am now on my third cancer...breast, bladder, and malignant melanoma...and there is no history of cancer in my family!
Please let us know the results....
