Aldesleukin (Proleukin®) is a type of immunotherapy drug used to treat kidney cancer. It is sometimes called interleukin-2 or IL2. It may sometimes be used to treat other cancers. It is best to read this information with our general information about immunotherapy and the type of cancer you have.
Aldesleukin is a man-made version of a protein the body produces naturally in very small amounts. It stimulates the body’s immune system (our defence against infection and disease) to fight some types of cancer. It encourages a particular type of white blood cell to recognise and destroy the cancer cells.
Your doctor will talk to you about this treatment and its possible side effects before you agree (consent) to have treatment.
