Sunitinib is a type of targeted therapy drug called a tyrosine kinase inhibitor. It works by blocking (inhibiting) signals in cancer cells that make them grow and divide. This may help to stop the cancer growing or slow it down.
Sunitinib can also stop cancer cells from developing new blood vessels. This reduces their supply of oxygen and nutrients, so the tumour shrinks or stops growing.
It’s best to read this information with our general information about the type of cancer you have. During treatment, you will see a cancer doctor and a cancer nurse. This is who we mean when we mention doctor or nurse in this information.
