Hematuria & pelvic pressure & burning. culture negative for uti. dr. says maybe small polyp. i'm worried bladder cancer. what else could it be?

A UTI: It is true that in women older than 60 years, having a history of smoking, and having gross hematuria are the strongest predictors of urologic cancer. However, the most likely cause of your symptoms is a UTI (if there are no vaginal sx) . Culture negative or not, the recommendation is to treat empirically according to standard clinical guidelines for UTI. Culture negative UTIs are common in women.
