Alice Pyne's emotional blog, along with her motto: "One life... live it!" has touched millions of hearts around the world.
She was diagnosed with terminal Hodgkins Lymphoma when she was just 12, but she has since become a powerful campaigner.
Alice's blog, a "bucket list" of things she wanted to achieve before she dies, received over a million hits in one day.
Earlier this year the Cumbrian teen finally completed her bucket list, which included whale watching in Vancouver and swimming with sharks.
But Alice says the most important thing her bucket list was to get people to sign up to be a bone marrow donor.
She has now managed to get more than 40,000 people in the UK to join the register.
Together with Vicky and dad Simon, kind-hearted Alice also set up a charity called Alice's Escapes earlier this year - to provide holidays to the Lake District for families with a seriously ill child.
Alice, who is receiving palliative treatment, has also raised £100,000 for different charities with younger sister, Milly, 14.
