Targeted therapies are used to stimulate the immune system or control the growth of cancer cells. They may be called biological therapies.
Different types of targeted therapy may be used to treat advanced melanoma. Some are available on the NHS and others are only used in clinical trials at the moment.
If a drug is not routinely available on the NHS, there may be other ways you can get access to it. Your cancer doctor can give you advice.
We have more information about immunotherapy and cancer growth inhibitors and information about specific therapies.
