Early signs show a young boy's tumour is reducing in size after treatment.
After three cycles of chemotherapy, the growth in Mason Wallace's leg has decreased by 60%.
The 11-year-old, from Borough Green, was diagnosed with Ewing Sarcoma, an aggressive cancer, in March 2019.
He was playing outside with his friends when his little brother Lennie, six, kicked him in the leg whilst playing football.
His leg swelled and his father, Denny Wallace, 34, took him to Maidstone Hospital to have it examined.
Upon first inspection, the doctors thought the swelling was caused by an old fracture in Mason's leg and sent him home.
The family were called back to the hospital around a week later to be told that the injury had helped them identify a tumour in the then-10-year-old's lower leg.
Without this turn of events, Mason's cancer may not have been found as quickly.
Denny said: "When we found out, we said Lennie was our hero, despite kicking his brother in the leg."
Three weeks after his diagnosis, Mason started his first cycle of chemotherapy to tackle the cancer.
Although the growth appears to be reducing, the boy still has a long way to go in his treatment journey.
He has to undergo months of radiotherapy, chemotherapy and an operation to remove two to three inches of the bone in his leg.
The Disney-fanatic is currently receiving treatment at The Royal National Orthopaedic Hospital in Middlesex, which runs one of the largest sarcoma services in Europe.
Mason has also recently been diagnosed with autism which has made the process hard for him to deal with.
His father said: "He's fed up of being poked and prodded every five minutes, it's getting to him."
The cancer diagnosis has put a significant strain on Mason's family, emotionally and financially, especially on his father who has sole custody of his three children.
"I'm exhausted from it all but at the moment I just have to focus on Mason... it's the hardest thing I've ever had to deal with" - Denny Wallace
Sadly, a close family member was diagnosed with the same cancer as Mason and sadly passed away recently which plays on Denny's mind.
To support the family, Mason's aunt, Taylor Wallace, decided to start organising a charity football game at the Red Bull Pub, Eccles.
The event will also feature stalls, a BBQ, bouncy castles and other fun activities.
All the money raised at the event on August 3 will go towards a family trip to Disney World Florida, something which Denny has dreamt of doing for many years with his children.
Taylor enlisted the help of friend Nicola Toms who has planned charity events in the past.
Nicola said on the fundraising page: "Mason and his family need this as they have had such devastating news and they really are such a wonderful family."
