How do you rule out bladder cancer?

Tests for bladder cancer look for different substances and/or cancer cells in the urine. Urinalysis: One way to test for bladder cancer is to check for blood in the urine ( hematuria). This can be done during a urinalysis, which is a simple test to check for blood and other substances in a sample of urine.

Cystoscopy. Cystoscopy is the key diagnostic procedure for bladder cancer. It allows the doctor to see inside the body with a thin, lighted, flexible tube called a cystoscope. Flexible cystoscopy is performed in a doctor’s office and does not require anesthesia, which is medication that blocks the awareness of pain.

If an abdominal CT scan shows a normal bladder, don’t celebrate yet. But if it comes back indicating cancer, don’t panic yet, either. About 80,000 people in the U.S. are diagnosed with bladder cancer every year. The five year survival rate, on average, is about 76.8 percent.

What is the survival rate for bladder cancer?

The five year survival rate, on average, is about 76.8 percent. This not-so-good survival rate is a function of the disease being caught at a later stage than it is of just a hard-to-treat cancer. About four times more men get bladder cancer than do women.

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.

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 tumour and whether a bladder cancer has spread. Ultrasound is able to differentiate between fluid-filled cysts and solid tumours, however, it cannot determine if a tumour 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.

How accurate is a CT scan for cancer? A research-based answer

No single imaging test is 100% accurate in detecting abnormalities. There may be a misdiagnosis due to the quality of the scan or due to the expert reading the scan.

How does a CT scan work?

Drawbacks of a CT scan

While a CT scan is a good imaging test to screen for cancer, it does have some limitations. It’s not the best test to screen for different types of cancers in all areas of the body. Another limitation of CT scanning is that there is a high rate of nodule detection.

Is an MRI scan a better alternative to a CT scan alone?

Due to the risk of radiation with CT scan, a safer alternative is an MRI (magnetic resonance imaging) scan.

Which scan is better?

The answer to this question is “It depends.” As discussed earlier, no single imaging test is confirmatory and medical practitioners may go back and forth as needed. For instance, they may order a CT scan and if they see something and are unsure about it, they may order an MRI, and vice versa.
