Scores of heartwarming messages of support have flooded in for Bradley Lowery and his family.
The five-year-old's parents have revealed that the treatment to prolong his life is "not working".
SAFC fan Bradley was first diagnosed with neuroblastoma in 2013 and had looked to have beaten the illness in 2014.
But it returned as doctors discovered during one of his check-ups.
His family were told in December that he could not be cured.
In a post on Bradley's Facebook page, his parents Gemma and Carl wrote: "We have just got back from the hospital with news no parent should ever have to hear.
"Scan results show treatment that Bradley has been receiving is not working, this means we will not get him cancer free as this was our last option.
"We can still go to London and receive the trial there however this is a phase one trial and hasn't shown any success in neuroblastoma up to now.
"We are understandably heart broken about the recent news hearing this type of thing never gets easier.
"We don't know how long it will be before the cancer wins, but what we do know is that we will continue to make memories and enjoy our super hero every second of the day."
