My wife has had blood in her urine recently, and has had a diagnosis of UTI. She was prescribed an antibiotic and had a second UTI within 2 weeks time, followed by a period-normal cycle since her last. she has had a cat scan today, but I am concerned something more may be wrong. She is a healthy 48 year old, with a mother who had uterine cancer, and a sister who had cervical cancer. Should I be worrying?
