Dillan was first diagnosed in 2020 during the Covid-19 lockdown after his mum noticed him limping and took him to hospital.
Blood tests later revealed he had the cancer, and he underwent years of chemotherapy, a bone marrow transplant, and further treatment in the US.
In February, Ms Ramsey said test results had showed cancer, with the family being told to “enjoy this time” as there was no treatment.
Ms Ramsey said the family had “poured every penny” of their savings into Dillan’s care, adding they had “lost everything from fighting for so long”.
An online fundraiser to support his family has raised more than £650,000.
She thanked people for their “continued support, love and condolence, it means the world to us and we are so grateful to you all”.
