Bladder cancer is the growth of abnormal tissue (tumour) in the urinary bladder (referred to as ‘the bladder’). There are several stages of bladder cancer. Your treatment and experience depend on the specific characteristics of the tumour and the expertise of your medical team. A tumour that grows towards the centre of the bladder without growing into the muscle tissue of the bladder is called non–muscle invasive. These tumours are superficial and represent an early stage. This is the most common type of bladder cancer. In most cases, these tumours are benign and rarely spread to other organs, so they are not usually lethal.

This type of cancer has a higher chance of spreading to other parts of the body (metastatic) and is harder to treat.
