Micrograph of Invasive urothelial carcinoma high grade. Invasive urothelial carcinoma is a type of Transitional cell carcinoma (TCC, also urothelial cell carcinoma or UCC) and is a type of cancer that develops in the urinary system: the kidney, urinary bladder, and accessory organs. It is the most common type of bladder cancer and cancer of the ureter, urethra, and urachus. Invasive urothelial carcinoma originates from tissue lining the inner surface of these hollow organs - transitional epithelium. It can extend from the kidney collecting system to the bladder.
