What is the blue light in a cystoscopy?
Fluorescence cystoscopy (also known as blue light cystoscopy) may be done along with routine cystoscopy. For this exam, a light-activated drug is put into the bladder during cystoscopy. It’s taken up by cancer cells. When the doctor then shines a blue light through the cystoscope, any cells containing the drug will glow (fluoresce). This can help the doctor see abnormal areas that might have been missed by the white light normally used.
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.
What is a physical exam for bladder cancer?

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.
Imaging Techniques To Detect 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 to find bladder cancer?
Most doctors recommend a cystoscopy to find bladder cancer, and it’s often performed without anesthesia. During this procedure, the doctor inserts a long, thin tube with a camera into the urethra to see the inside of the bladder for growths and collect a tissue sample ( biopsy ). The tissue is studied in a lab to search for cancer and obtain more information. During a cystoscopy, doctors may also perform a fluorescence cystoscopy, or blue light cystoscopy, inserting a light-activated drug into the bladder and seeing whether any cancer cells glow when they shine a blue light through the tube.
What tests are done to check for cancer in urine?
Tests may include: Urinalysis (looks for blood in urine) Urine cytology (looks for abnormal cells in urine) Urine culture (looks for an infection, rather than cancer) For patients who have symptoms or have had bladder cancer in the past, newer tests that look for tumor markers in urine may include:
What is the procedure to remove bladder tumor?
