infection, stone or tumor
welcome to the forum.
Most common causes for blood in urine in that order are
1. Infection in the urinary tract
2. Stone(s) in the urinary tract
3. Tumor in the urinary tract- usually bladder.
There may be some rare causes also.
So the next steps would be to do the following tests---
1. Urine culture and sensitivity to look for the bacteria causing the infection.
scan of the urinary tract to look for stone or tumor mass.
Based on the results, a diagnosis is made and treatment can be started.
This is quite treatable and there should be no worry.
Hope this helps,
Wish you good health,
