Being a "newbie" myself, having only begun on this unwelcomed journey this past summer, I too am slowly learning all the definitions and abbreviations concerning bladder cancer.

As I watch the Olympics, I can sort of compare all the members who comprise this group to Olympians since each person is facing his/her own unique challenge, earnestly trying to remain strong and doing their absolute best to overcome any obstacles to success - this being to beat bladder cancer.

Definitions of TURBT and BCG:

Transurethral Resection of Bladder Tumor (TURBT)

TURBT is a surgical procedure that allows healthcare providers to both diagnose and treat bladder cancer. It involves the removal of tumors from the bladder wall using a thin tube called a resectoscope, which is inserted through the urethra, eliminating the need for external incisions.

How is TURBT Performed?
Preparation: Patients may receive general or spinal anesthesia to ensure comfort during the procedure. The healthcare team will provide specific instructions on how to prepare for TURBT.

Procedure: The resectoscope, equipped with a camera and a wire loop, is inserted into the bladder through the urethra. The doctor uses the camera to locate tumors and the wire loop to cut and remove them. This procedure typically takes about 15 to 90 minutes.

Biopsy: The removed tissue is sent to a laboratory for analysis to determine the cancer's stage and grade, which helps in planning further treatment.
