But it's important to be aware of the possibility. Advanced kidney, bladder, or prostate cancer can cause blood in urine. The bleeding typically comes from the tumor itself, Dr. Smith says, though it can also be the result of irritation or inflammation. These cancers can also have symptoms like painful urination, fatigue, and pain in your back, side, or pelvis.
Again, it's probably not cancer, but the slight chance that it could be is exactly why it's so important to have bloody urine checked out by a doctor.

The blood in your urine must have originated from somewhere within the urinary tract the kidneys, bladder or the tubes through which urine passes. This is often the result of a urinary tract infection UTI , such as cystitis. There are various conditions and serious diseases that may cause blood in urine. Common ones include:. A change in urine color caused by drugs, food or exercise might go away within a few days.
Bloody urine looks different, but you might not be able to tell the difference. It's best to see your doctor anytime you see red-colored urine. Your urinary system — which includes your kidneys, ureters, bladder and urethra — removes waste from your body through urine.
Your kidneys, located in the rear portion of your upper abdomen, produce urine by filtering waste and fluid from your blood. In hematuria, your kidneys — or other parts of your urinary tract — allow blood cells to leak into urine.
Various problems can cause this leakage, including:. Urinary tract infections. These occur when bacteria enter your body through the urethra and multiply in your bladder. Symptoms can include a persistent urge to urinate, pain and burning with urination, and extremely strong-smelling urine. For some people, especially older adults, the only sign of illness might be microscopic blood in the urine.
A bladder or kidney stone. The minerals in concentrated urine sometimes form crystals on the walls of your kidneys or bladder. Over time, the crystals can become small, hard stones. The stones are generally painless, so you probably won't know you have them unless they cause a blockage or are being passed. Your kidneys filter your blood and remove waste and extra water, which become urine, the U. National Library of Medicine explains. Kidney infections share a few symptoms with bladder infections, including frequent, painful peeing and bloody urine like a bladder infection, this is due to irritation and inflammation in your urinary tract, Doreen Chung, M.
If you suspect you have a kidney infection, see your doctor ASAP. If your case is severe, you may need to be hospitalized so you can receive IV antibiotics and fluids, the Mayo Clinic says. Fun fact about your pee: It contains minerals. But if your urine is too concentrated, those minerals can form crystals on the walls of your kidneys or bladder, the Mayo Clinic says, and eventually transform into small, hard stones.
Or they can lead to a ton of pain, along with red flags like bloody pee. This might happen when your body tries to pass a stone by peeing it out or if a stone blocks part of your urinary tract. Stones and especially kidney stones can cause sharp pains in your back, groin, side, or lower abdomen, a constant need to pee even though nothing comes out when you try, pain when you pee, cloudy or bad-smelling urine, and pink, brown, or red pee due to blood, the NIDDK says.
This is because stones can create micro-scratches in the lining of your urinary tract, Dr. Linehan says. If you have a larger stone, though, your doctor can use shock waves to smash it into smaller pieces so you can pee them out, the NIDDK explains.
Your doctor may also insert long, thin tools into your urethra to locate the stone, then remove it or break it into smaller pieces. Microscopic or visible blood in your pee is a common sign of glomerulonephritis, which is when your kidneys' filtering system becomes inflamed, according to the Mayo Clinic. This may happen as a side effect of a systemic disease that can damage your kidneys , like type 1 or type 2 diabetes.
