The type of bladder cancer depends on the type of cell in which cancer develops.

Transient cell urinary bladder cancer

Approximately 9 out of 10 cases of bladder cancer are in the transient cells; this cancer is also called urothelial cancer. Transient cell bladder cancer develops from bladder mucosal cells, called transient cells.

Non-muscular invasive bladder cancer

In superficial bladder cancers, tumor cells are found only in the bladder mucosa, not in the deeper layers of the bladder wall. Early bladder cancer usually occurs as small mushroom-shaped formations. They grow from the bladder mucosa.

Squamous cell bladder cancer

Approximately 5% of bladder cancers are squamous cell cancers. Squamous cells are flat cells that make up the wet, skin-like tissues that makeup body organs.

Adenocarcinoma

This is a very rare type of bladder cancer. Approximately 1-2% of diagnosed urinary bladder cancers are of this type. Adenocarcinoma develops in the bladder mucosa.
