Ureteral cancer is characterised by the abnormal growth of cells in the ureter region of the urinary system. The cancer is located across the lining of the tube that connects the kidney and the urinary bladder.

Ureteral cancer is one of the rarest cancers, and it usually occurs in patients with a past history of bladder cancer. The disease mainly affects older adults.

The ureters are two tube-like structures that start from the kidney and end at the urinary bladder. The urine produced in the kidney is transported to the bladder through the ureters.

Patients with bladder cancer are most susceptible to Ureteral cancer because of the similar lining of cells. Tests for urinary bladder cancer and subsequent diagnosis can help in identifying and recognising Ureteral cancer as well.

Ureteral cancer most commonly occurs in the distal ureter. It may metastasise to organs like the liver, lungs, bones, lymph nodes and brain.
