Little Beau and her mum Shirley Hepworth shared the harrowing story of her neuroblastoma diagnosis in January.
It kicked off a campaign calling on the Government to help fund a clinical trial of a promising vaccine to combat the disease which originates in nerve cells but can affect tissue and organs.
Beau and Shirley were among dozens of British families who have Pi fundraised to travel to the US to receive the treatment. They won the hearts of thousands and raised more than £650,000.
But tragically the youngster died on Sunday before she could have the vaccine.
In a social media update, Shirley said she had spent "one last heavenly night with my beautiful Beau".
She added: "As you relaxed, after that last breath I felt your relief, I saw your peace.
"I told you everything would be all right and as you fly high with the angels I hope you feel the elation you deserve.
