I had uterine cancer, and now I seem to have uti's more often than I would like to have them. So, I can see that might become a problem for you. I don't know what stage you were, but I was stage IIIC when I was diagnosed. I didn't receive a cat scan til my treatment was completed. Even then, it was only for the chest, abdoman, pelvis. About 8 months later, another doctor order a Pet Scan. It found thyroid cancer, which the cat scan missed. So, if you feel you want to be checked more thoroughly, discuss it with your onc.
