Types and Staging for Bladder Cancer
A bladder is an organ situated in the pelvis that functions as a storehouse for urine before its discharged from the body. The bladder considered one of the vital organs of the urinary tract along with the uterus, urethra, and the kidney. The bladder is lined by a cellular layer collectively known as the urothelium. The muscular wall of the bladder is referred to as the muscularis propria. Bladder cancer is caused when these cells of the bladder, particularly the urothelial cells, grow and divide uncontrollably to form abnormal cells or a mass, or tumor. Bladder cancer occurs in several different types, which much be diagnosed by taking a small sample of tumor cells and examining them in a laboratory: 1. Urothelial carcinoma This is the most common type of bladder carcinoma accounting for 90% of bladder cancer patients. As the name suggests, this cancer initiates in the urothelial cells of the urinary tract. This type of carcinoma is also called the transitional carcinoma or TCC. 2. Squamous carcinoma This second type of bladder cancer develops in the squamous cell, as the cells become inflamed. This carcinoma is less common and occurs in only 4% of patients with bladder cancer.
