Transitional Cell Carcinoma, Causes, Signs and Symptoms, Diagnosis and Treatment.

Transitional cell carcinoma, also called urothelial carcinoma, is a type of cancer that typically occurs in the urinary system. It is the most common type of bladder cancer and cancer of the ureter, urethra, and urachus. It accounts for 95% of bladder cancer cases.[1][2]

It is the second most common type of kidney cancer, but accounts for only five to 10 percent of all primary renal malignant tumors.[3]

Transitional cell carcinomas arise from the transitional epithelium, a tissue lining the inner surface of these hollow organs.[4]

When the term “urothelial” is used, it specifically refers to a carcinoma of the urothelium, meaning a transitional cell carcinomas of the urinary system.
