A YOUNGSTER battling a rare and aggressive form of cancer has flown back from the USA after preventative treatment.

Theo Power, seven, was diagnosed with advanced neuroblastoma in July 2015 and underwent intense treatment to cure him.

Following the successful treatment, doctors said the chances of a relapse without further treatment were very high.

The Feniscowles Primary School pupil, from Lower Darwen, visited the Helen DeVos Children’s Hospital in Michigan for the treatment.

Theo underwent a Difluoromethylornithine (DFO) clinical trial, which is not available in the UK.

He will have to return to the hospital every three months for two years until the treatment is complete.

The treatment was made available after wellwishers raised £160,000.

Graham Jordan, Theo’s grandad, said he was extremely brave to fly all the way to America.

He said: “He was exceptional and didn’t complain at all throughout the treatment.

“It was a busy week for him, having a variety of blood tests and other tests.

“Theo needed to go out there because despite being cancer free at the moment, it could easily come back.

“He has three months worth of medication to take now until he goes back for more tests and to get his next batch of medication.

“Theo met another young boy out there from Belfast who has the same condition as him.

“It made the experience more real for the family meeting someone else with it.”

The youngster joined the Blackburn Rovers first team squad at the club’s Brockhall training complex before going out to America.

They watched the first team squad train before Theo and his brothers, Joshua 11, and Jayden, nine, took penalties against keepers Jason Steele and David Raya.

The youngster celebrated his return to the UK with his friends and family yesterday on his seventh birthday with an event at Blackburn Golf Club.

Mr Jordan said: “Theo had a fantastic time yesterday, he was the life and soul of the party.

“It’s been amazing to see him cope with the whole journey so well, he’s such a strong person.

“He loves planes so flying over the America was a great experience for him.”

He added that getting the treatment will play a ‘big part’ in making the sure the cancer does not return.
