Jamie was diagnosed with non-Hodgkin lymphoma just months after his family celebrated his sixth birthday.
Jamie's mum says; "It was such a shock. I never thought my little boy would ever get cancer.
"It all started weeks after his sixth birthday. Jamie had been run down for a while and didn’t seem to be getting any better. I took him to the GP, but the doctor couldn’t see anything significantly wrong.
"Then Jamie developed a rash on his body, so I took him straight back to the GP, this time really worried. At first they weren’t sure what was wrong with him. The rash indicated that he may have meningitis, or possibly leukaemia, another form of blood cancer.
"Jamie was sent straight to hospital for all sorts of tests. A bone marrow sample was taken, which revealed that Jamie had a blood disorder called hypereosinophillia, meaning he had too many of a particular type of white blood cell.
"At the Children’s Cancer Unit at the Royal Victoria Infirmary in Newcastle, Jamie was prescribed a mixture of chemotherapy drugs and steroids to treat this blood disorder. Though he seemed to be recovering, the drugs hit him hard and he was unable to walk. Jamie had to use a wheelchair, which is very difficult for an active young boy to get used to.
"Only three months later, just when we thought he was on the mend, he developed lumps on his body. We went back to the hospital where a biopsy was performed to examine these lumps. We were then told that the lumps were malignant and "Jamie had non-Hodgkin lymphoma, a type of blood cancer.
"Jamie returned to hospital where he was given 10 months of the most intensive chemotherapy. For the two years following this he was in and out of hospital on maintenance chemotherapy to make sure the blood cancer did not come back.
"I’m so proud of Jamie. He was absolutely amazing through all of this, and took everything that was thrown at him. He is now nearly 13 years old, in remission and back at school.
"Last year he took part in the Great North Run in Newcastle with his scout group. He managed to complete it through sheer determination, and saw lots of other children running for Leukaemia & Lymphoma Research. This made him want to get involved too.
"This year he will be running with one of his school friends in support of Leukaemia & Lymphoma Research.
"Research into improved treatments is vital. After seeing what Jamie has gone through anything that can help others is so important."
