Gemma, now 31, was just five years old when she finished her treatment for Non-Hodgkin lymphoma - a type of cancer that develops in the lymphatic system.
Whilst undergoing treatment for the disease, her closest friends and family walked in fancy dress from Penistone to Sheffield Children’s Hospital to raise funds - and they’ll do the exact same next month to mark 25 years since the end of her treatment.
Gemma, of Penistone, told the Chronicle: “This year marks 25 years since I had my treatment.
“Back then my family did the same walk and so I’m going to be getting involved this time - also in fancy dress - to raise money for the charity P.A.C.T.
“It’s quite weird that I’m going to be doing it.
“They did the walk for me originally and now I’m getting involved.”
P.A.C.T is a charity which offers emotional and practical support to families of children who are undergoing treatment for cancer or leukaemia at Sheffield Children's Hospital.
The walk kicks off on October 9.
