Constant bladder irritation or inflammation for many months or years leads to the formation of thin flat cells in the bladder. In Squamous Cell Carcinoma cancer develops in these cells. It accounts for 3 to 8 % of the bladder cancer. This is an invasive type bladder cancer as it penetrates in to the walls of the bladder.
