What is the potential of urine?
Other bodily fluids, like urine, also have the potential to reveal what’s going on in our bodies. “Urine gives a great insight into what’s going on inside our bodies,” says Mr Richard Bryan from the University of Birmingham, a Cancer Research UK-funded bladder cancer surgeon who’s working on a test to detect the disease in its early stages.
Is urine a normal cell?
Pee contains normal bladder cells that have dropped off from the lining of the urinary tract as part of the normal cell lifecycle. “If you have disease, diseased cells will be there too,” says Bryan, whose research is looking for the DNA of bladder cancer cells in urine.
Can a urine culture show cancer?
If you’re having urinary symptoms, this test may be done to see if an infection (rather than cancer) is the cause. Urinary tract infections and bladder cancers can cause the same symptoms. For a urine culture, a sample of urine is put into a dish in the lab to allow any bacteria that are present to grow. It can take time for the bacteria to grow, so it may take a few days to get the results of this test.
How does ultrasound help with bladder cancer?
Ultrasound uses sound waves to create pictures of internal organs. It can be useful in determining the size of a bladder cancer and whether it has spread beyond the bladder to nearby organs or tissues. It can also be used to look at the kidneys. This is usually an easy test to have, and it uses no radiation.
Why is bladder cancer found?
Bladder cancer is often found because of signs or symptoms a person is having. Or it might be found because of lab tests a person gets for another reason. If bladder cancer is suspected, exams and tests will be needed to confirm the diagnosis. If cancer is found, more tests will be done to help find out the extent ( stage) of the cancer.
What type of tube is used for bladder cancer?
If bladder cancer is suspected, most doctors will recommend a cystoscopy. . A urologist uses a cystoscope, which is a long, thin, flexible tube with a light and a lens or a small video camera on the end. For details on how this procedure is done, see Cystoscopy.
What is the biopsy for bladder cancer?
A biopsy is when tiny pieces (called samples) of the abnormal-looking tissue are taken out and tested for cancer cells. If bladder cancer is suspected, a biopsy is needed to be sure of the diagnosis.
Is bladder cancer invasive or noninvasive?
This is very important in deciding treatment. If the cancer stays in the inner layer of cells without growing into the deeper layers, it’s called non-invasive. If the cancer grows into the deeper layers of the bladder, it’s called invasive. Invasive cancers are more likely to spread and are harder to treat.

Imaging Techniques To Detect Bladder Cancer
Imaging techniques, which include ultrasound, computed tomography (or CT) scanning, magnetic resonance imaging (or MRI) and x-ray approaches, provide an important means of assessing the urinary tract, including the kidneys, and play an important role in the detection, diagnosis, and monitoring of bladder cancer.
Detecting bladder cancer with ultrasound
An ultrasound (which may also be referred to as a sonogram) uses high frequency sound waves to produce images of internal organs. Echoes, which are created as sound waves bounce off organs and tissues, produce computer images that provide information on the structure and movement of organs and the blood flow through vessels.
How do ultrasounds help detect and monitor bladder cancer?
An ultrasound of the urinary tract can help assess the size of a bladder tumor and whether a bladder cancer has spread. Ultrasound is able to differentiate between fluid-filled cysts and solid tumors, however, it cannot determine if a tumor is cancerous. Ultrasound can also be used to guide a biopsy needle to sample a suspected cancer.
Detecting bladder cancer with CT scans
A CT scan uses x-rays to obtain cross-sectional images of the body. Compared to a general x-ray test, which directs a broad x-ray beam from a single angle, the CT scan uses a number of thin beams to produce a series of images from different angles.
Other imaging approaches to detect or monitor bladder cancer
An MRI scan uses radio waves and magnets to produce more detailed pictures of soft tissues. MRI scans can show whether bladder cancer has spread to other tissues or to the lymph nodes. To improve the quality of the images it’s sometimes necessary to administer an intravenous dye.
