Transitional cell carcinoma
Transitional cell carcinoma, also urothelial cell carcinoma, is the most common type of bladder cancer, and also appears in the ureter, urethra, urachus, and kidney. Transitional cell carcinoma arises from the transitional epithelium, a tissue lining the inner surface of these hollow organs. It is associated with phenacetin, aniline dyes, cyclophosphamide, smoking, and those who drink excessive alcohol.
