Blood in the urine is sing of bladder cancer
In most cases, blood in the urine (called hematuria) is the first sign of bladder cancer. Sometimes, there is enough blood to change the color of the urine to orange, pink, or, less often, darker red. Sometimes, the color of the urine is normal but small amounts of blood are found when a urine test (urinalysis) is done because of other symptoms or as part of a general medical checkup.
Changes in bladder habits or symptoms of irritation
Bladder cancer can sometimes cause changes in urination, such as:
- Having to urinate more often than usual
- Pain or burning during urination
- Feeling as if you need to go right away, even when the bladder is not full
- Having trouble urinating or having a weak urine stream
Signs and symptoms
Bladder cancer characteristically causes blood (redness) in the urine. This blood in the urine may be visible to the naked eye (gross/macroscopic hematuria) or detectable only by microscope (microscopic hematuria). Hematuria is the most common symptom in bladder cancer. It occurs in approximately 80-90% of the patients.
Other possible symptoms include pain during urination, frequent urination, or feeling the need to urinate without being able to do so. These signs and symptoms are not specific to bladder cancer, and are also caused by non-cancerous conditions, including prostate infections, over-active bladder and cystitis. There are many other causes of hematuria, such as bladder or ureteric stones, infection, kidney disease, kidney cancers and vascular malformations.Patients with advanced disease refer pelvic or bony pain, lower-extremity edema, or flank pain. Rarely a palpable mass can be detected on physical examination.
The diagnosis of bladder cancer can also be done with a Hexvix/Cysview guidedfluorescence cystoscopy (blue light cystoscopy, Photodynamic diagnosis), as an adjunct to conventional white-light cystoscopy. This procedure improves the detection of bladder cancer and reduces the rate of early tumor recurrence, compared with white light cystoscopy alone. Cysview cystoscopy detects more cancer and reduces recurrence. Cysview is marketed.
