The first warning sign of bladder cancer is normally blood in the patient’s urine (hematuria). The blood may appear on a urine test, or the patient may notice that the urine is darker or more reddish in color than usual. Other common signs and symptoms of bladder cancer may include the following:

• Pelvic pain
• Pain in the abdomen or lower back
• Painful urination
• Changes in bladder habits
• Having to urinate more frequently
• Inability to urinate

Individuals who experience any of these signs or symptoms should notify their physician. Although these signs and symptoms may indicate bladder cancer, the most common causes of bladder symptoms are other medical conditions such as infections.
