Any bleeding in the urine is not normal and should be investigated.
The most thorough test for bladder cancer is a cystoscopy. Other causes of bleeding in the urine can be from kidney stones, infections, or other kidney disease.
In addition to the cystoscopy, you can also consider a pyelogram to evaluate the lower GU tract.
These options can be discussed with your personal physician, or in conjunction with a urologist.
Followup with your personal physician is essential.
