Description

Urine tumor markers are specific substances or proteins that can be detected in the urine to aid in the diagnosis of bladder cancer. These markers are released into the urine by cancer cells during their growth and progression. By analyzing the levels of these markers in the urine, doctors can identify potential cases of bladder cancer and monitor the disease progression.

Sensitivity: The ability of the test to correctly identify individuals with bladder cancer.

Specificity: The ability of the test to correctly exclude individuals without bladder cancer.

Accuracy: The overall reliability of the test in determining the presence or absence of bladder cancer.

Non-invasiveness: As the markers are analyzed from a urine sample, the test is non-invasive and relatively easy to perform.

Early detection: Urine tumor marker tests can detect bladder cancer at an early stage, increasing the chances of successful treatment.
