Many possibilities : Blood in the urine can be caused by a cancerous tumor, a bladder polyp, an infection, interstitial cystitis, a kidney stone, and kidney disease. Additionally, blood can also be present on a urinanalysis from extra-urinary sources such as vaginal orrectal bleeding.

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.

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

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.

Does blood in the urine always mean cancer?

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.

Bright red ?cystitis: If u have symptoms of burning on urination & frequency of urination. Bright red with no other symptoms could be a small vascular malformation (like vascular nevus) of kidney. Brown urine with proteinuria suggests kidney disease. Unusual for kidney or bladder tumor at your age. Microscopic hematuria could be caused by a kidney stone. Microscopic hematuria often benign. Needs work-up & ? Cystoscopy.
