'Superman' Gavin (4) back on his feet after 'miracle' US surgery
Brave Gavin Glynn is up and walking once again after surgery, his family has announced.
The four-year-old has been recovering in hospital following a successful "miracle" procedure in America last week.
The child, from Greystones in Co Wicklow, has been battling the rare cancer Rhabdomyosarcoma since he was just 17 months old has been receiving treatment in the MD Anderson Cancer Centre in Houston, Texas.
His parents, Jayne and John have shared photographs of their son using a stroller to hold himself upright as he leaves the intensive care unit.
Wearing his favourite Superman t-shirt, Gavin walks alongside the bags and tubes needed to continue his intravenous treatment in the children's cancer ward.
Posting an update to the Facebook page, Team Gavin Glynn, his family said: "The medical team are very happy with his progress and recovery so far which is great news.
"Look who's up walking...Over the last few days Gavin has increased from 20 steps to 50 steps and then today walked all the way to the playroom and also most made it back again," they continued.
Last Wednesday, Gavin underwent a gruelling 12-hour operation.
The innovative open surgery on his tumours has been accompanied by heated chemotherapy as part of an eight-week course of treatment.
"He is still very sore but we need to push him a bit now to get up and moving. We knew he could do it, and he sure did," his parents continued.
Doctors had told his parents that the invasive procedure would mean Gavin's bladder and colon would have to be removed.
It was expected that the Superman fan would have two permanent bags fitted as a result, however the medical staff where fortunately able to remove the tumours without touching the bladder and colon.
The success of the surgery is all the more astonishing after the family received some bad news about their son's condition on arrival in the states.
In a previous update on the social networking site dad John described how an MRI scan found that the tumours had increased in size since they left Dublin.
Gavin is currently spending a week recovering in intensive care with his parents staying in the hospital round the clock.
The Glynn family previously thanked the public for their support after their €350,000 fundraising target to get the operation underway was last month reached within one week.
