I've just completed a ten day course of Ciproflaxin and UTI symptoms have disappeared, however, follow up urinanalysis still shows bacteria. This will be the third course of UTI treatment since September. I had a UTI in July and one earlier in the year in March. I am being referred to a urologist. My question, however, is whether the recurrence of UTIs/chronic UTIs is a sign of bladder cancer or is a risk factor in developing bladder cancer. I have no blood in the urine and all symptoms disapper within two to three days of starting antibiotic treatment. I was prescribed Bactrim in March, to which I became violently ill. I received Macrobid in July as well as in September, October, Amoxocillan, then Cipro. All preventative hygiene habits are followed and I've abstained from sex to rule out bacteria transmission - which, it appears sexual activity is not a factor. Should I be worried and planning my last will and testament, or is there a potentially simple explanation?
