This scheme is run by the International Charter of rights for young people with cancer and is based in Australia, the UK, New Zealand and the US. The website lists the rights for young people with cancer and describes how young people are actually affected by cancer. They also have a list of stories from various people who were diagnosed with cancer.
A person participates by signing the charter to support this organization. It is simple as all you are required to do is enter a bit of basic information about yourself and then you can help to make a difference to young people with cancer in many different places.
