What is bladder cancer?
Bladder cancer starts when abnormal cells appear in the lining of your bladder or in the bladder wall. This can affect how the bladder works.
Bladder cancer can grow in different ways:
Non-muscle invasive cancer: This only affect the cells in the lining of your bladder.
Muscle invasive cancer: This grows into a deeper layer, such as the muscle of the bladder wall
The type of bladder cancer will affect the type of treatment you need.
What is the bladder and what does it do?
Your bladder is a hollow organ like a balloon that sits in your pelvis - the lower part of your tummy between your hips. The bladder has a number of layers. The bladder wall is made of muscles and lined with cells known as urothelial (‘yur-o-thee-lee-all’) cells.
Your bladder stores urine (wee) until it is full. When you need go to the toilet, the bladder muscle contracts. This forces the urine out through a tube called the urethra.
