Warning Sign: Blood in Urine
Blood in the urine can be a sign of bladder cancer, either visible to the eye or picked up by routine testing. The urine may look darker than usual, brownish, or (rarely) bright red. Most commonly, blood in the urine is not caused by cancer, but by other causes. These include exercise, trauma, infections, blood or kidney disorders, or drugs, such as blood thinners.
Warning Sign: Bladder Changes
Bladder symptoms are more likely to come from conditions other than cancer. But bladder cancer can sometimes cause changes to bladder habits, including:
- Needing to go, with little or no results
- Having to go more often than usual
- Painful urination
- Difficulty urinating
