Understanding

Cancer is not a single disease with a single type of treatment. There are more than 200 different types of cancer, each with its own name and treatment. This section provides an overview of what cancer is.

  • What is cancer?

    Cancer starts when cells in our bodies become abnormal. The abnormal cells grow and divide and can form a tumour.

  • Cancer and cell types

    Cancers are grouped into types. Types of cancer often behave and respond to treatments in different ways.

  • About the bladder

    The bladder collects and stores urine. It is in the lower part of the tummy.

  • Types of bladder cancer

    There are different types of bladder cancer. The most common is urothelial bladder cancer, which is also called transitional cell carcinoma.

  • Signs and symptoms of bladder cancer

    Blood in the urine is the most common symptom of bladder cancer, but there are others to watch out for.

  • Why do cancers come back?

    Sometimes, tiny cancer cells are left behind after cancer treatment. These can divide to form a new tumour.
