Urinary System Cancer
The urinary system — also known as the renal system — produces, stores and eliminates nitrogen-rich by-products from the bloodstream through urination. Cancer in the urinary system can affect your bladder and/or kidneys.
Kidney cancer begins in the tubes or in the center of the kidney. It usually starts as a single mass of cells within the kidney and can grow quite large before being detected. The most common type of kidney cancer develops in the lining of the kidney's small filtering tubes, also known as renal cell carcinoma.
Most bladder cancers are transitional cell cancers. That means they begin in the inner lining of the bladder. Other types include cancers that form in the thin, flat cells of the bladder and cancer of the cells that produce and release mucus and fluids from the system. Older people are generally more susceptible to bladder cancer.
