Possibly: Blood in the urine (hematuria) can be microscopic (found only with testing) or "gross" (seen with the naked eye). Most causes of hematuria are benign (infection, inflammation, stones, hormonal, kidney problems), but even microscopic hematuia in a person with no symptoms can be an early sign of bladder or kidney cancer. Depending on the situation, testing is often recommended.

Possibly: Blood in the urine (whether microscopic or gross) must be evaluated by a urologist. The degree of hematuria does not necessarily correlate with the size of the problem, so the evaluation would include laboratory testing, imaging of the urianry tract, and cystoscopy - a procedure to look inside the urethar and bladder with a telescope. Possible causes include infection, stones, and malignancy.

A 37-year-old member asked:

If I have bladder cancer, would there be blood in my urine?

Dr. Moez Khorsandi

Yes: Bladder cancer may cause visible blood in the urine or microscopic blood in the urine which is only picked up by urine tests. Depending on the type of cancer, size, number of lesions, etc, blood may be visible to the naked eye but can also be absent with smaller lesions. Therefore, urine tests must be performed when bladder cancer is suspected.

No, but cancer is one of the possibilities and needs to be ruled out. There are many other benign causes from kidney stones to prostate disease (in men) that can cause blood in urine.

Not necessarily CA: Blood in the urine (hematuria) has many possible causes, including kidney/bladder stones or kidney cysts, urinary tract infections, urethral trauma. Cancers commonly associated with hematuria include renal cell carcinoma (a kidney cancer), and bladder cancer. (see also dr. Klauber's very important comment.).

Glomerulonephritis is the most common cause of hematuria in children. This is a medical condition most commonly after a streptococcal , best treated by a nephrologist, and also occurs less commonly in adults.
