Which procedure can be diagnostic or curative for bladder cancer?

• A. Abdominal ultrasound
• B. Urinalysis
• C. CT urography
• D. Cystoscopy with biopsy

Answer: (D)

Direct visualization of the bladder with a cystoscope lets you see the inner lining and identify suspicious lesions, while taking a biopsy provides the tissue needed to confirm cancer and determine its grade and depth. This histologic confirmation is essential for diagnosis and guiding treatment. In many cases, especially for small, non-muscle-invasive tumors, the same cystoscopic procedure includes removing the lesion via transurethral resection of the bladder tumor, which can be curative if all disease is resected and confined to the mucosa or submucosa. Imaging tests like ultrasound or CT urography can reveal abnormalities or help stage disease but cannot establish a histologic diagnosis or provide definitive local treatment. Urinalysis can show blood or infection but does not diagnose cancer. Therefore, cystoscopy with biopsy is the approach that can both diagnose and, in suitable cases, treat bladder cancer in the same procedure.
