There are many different causes of blood in the urine, and not all cases relate to cancer. Common causes of hematuria
- Urinary tract infections (UTIs): Infections in the bladder, urethra, or kidneys can cause blood in the urine. UTIs can also cause symptoms such as pain or burning during urination, frequent urination, and fever.
