Like other organs in the body, the bladder is made up of many types of cells. Cells divide in an orderly, controlled way to produce more cells when more cells are needed in the body. When cells divide in an abnormal, uncontrolled way, they can form either a benign or malignant tumor. Benign tumors are not cancerous and are generally not life-threatening. They can be removed surgically, and usually do not return.
Malignant tumors are cancerous.
The lining inside the bladder is where most bladder cancers form. Cancer cells can spread to nearby healthy cells and destroy them. The cancerous cells can also invade other parts of the body. Cancerous cells in the bladder can spread to other parts of the body through the blood and lymph systems.
