This is Rupert.

He is 6 years old, he loves Minecraft, lego, tractors and most of all being mischievously funny. Rupert has a crocodile (which is Rupert's name for his cancer) and he needs your help. Please read his crocodile journey on Facebook; Rupert's Revenge.

Since the age of 3, Rupert has undergone continuous intensive cancer treatment for stage 4 High Risk Neuroblastoma. A rare childhood cancer, affecting only 100 children a year, in the UK.

Sadly, Rupert's cancer remains and his specialist consultant in London explains that, Rupert's treatment is now in "uncharted waters", with no clear direction, as to what to do next, as there is no effective treatment left within the NHS.

Rupert has bounced through treatment, exceeding expectations and remains, not just well but he is full of energy.

On paper he shouldn't be! Even as I type this, I just can't believe that this is happening to our son. It is just a nightmare.

The best chance Rupert has of a future, of defeating his crocodile, is to pay for his treatment.

There is pioneering immunotherapy treatment, for neuroblastoma that is routinely used in America, and is proving to be very effective. Prolonging children's life's and helping children, with "refractory neuroblastoma", like Rupert, become cancer free. Subsequent vaccines to prevent future relapse, are also only available in America.

So, we have no choice but to try to take Rupert to America. To receive this treatment as soon as possible, before his cancer progresses, and its too late.

Everyday Rupert demonstrates his determination to succeed, to get on with his life despite the odds. Planning all the things he wants to do once he has defeated his crocodile; play football and rugby; go swimming. Or simply just being free from hospital and playing with his school friends. Rupert has not given up fighting his crocodile. So we must help him to carry on; to save his life.

We desperately need your help, we can not do this without you.
