Bladder Cancer

Make an Appointment

The bladder is located in the lower abdomen. It is a hollow organ with flexible muscular walls. It stores urine until a person is ready to urinate. Bladder cancer is a disease in which cancer cells grow in the bladder.

Three main types of cancer affect the bladder. They are named for the type of cell that becomes cancerous:

  • Transitional cell (urothelial) carcinoma—more than 90% of bladder cancers
  • Squamous cell carcinoma—about 4% of bladder cancers
  • Adenocarcinoma—about 1%-2% of bladder cancers
