Who is Bradley Lowery?

Bradley Lowery was a six-year-old boy from Blackhall Colliery near Hartlepool.

When he was 18 months old his parents were told he had been diagnosed with neuroblastoma – a rare cancer that affects infants.

The tumour was found in January 2013 just above his left kidney.

He beat the illness once but sadly relapsed in July 2016.

He spent his sixth birthday in hospital and his parents have set up a Facebook page for birthday messages for him.

What is Bradley Lowery’s Fight?

His parents set up a fund in the hope to raise enough money for him to travel to America to receive treatment there.

Doctors however said believe his illness became terminal and any treatment will merely prolong his life.

Any unused money donated will go towards setting up a charity in Bradley’s name to support other children and their families going through the same ordeal.

What’s his connection to Jermain Defoe?

Bradley was a huge football fan and a supporter of Sunderland.

Throughout his illness the club were keen to support Bradley and he struck up a friendship with England striker Jermain Defoe.

Bradley was lucky enough to lead the team out onto the pitch on a number of occasions, holding the hand of Defoe. He also accompanied  Defoe onto the Wembley pitch as the England star was recalled to the national team for a match against Lithuania in April.

Defoe has also visited Bradley on a number of occasions during his hospital treatment.

In January Bradley had a shot at the goal during the warm-up for Sunderland’s match against Chelsea.

His goal was picked as Match Of The Day’s goal of the month.

He was also invited to attend the BBC’s Sports Personality Of The Year.

What is neuroblastoma?

Neuroblastoma is a rare type of cancer that most commonly effects babies and young children.

It’s caused by special cells known as neuroblasts which are left behind from the womb.

It only affects around 100 children a year in the UK.

It’s most commonly found in the adrenal glands above the kidneys but can also occur in nerve tissue that runs along the spinal cord in the neck, chest, abdomen or pelvis.
