A British five-year-old boy is the world's youngest survivor of testicular cancer after his mother found a tangerine-sized tumour.
Jason Takor had just celebrated his third birthday when his frightened mother Zuzana made the horrifying discovery.
The youngster, from Bristol, needed radiotherapy and chemotherapy when the cancer spread after doctors removed his right testicle.
He has to have check-ups every three months after he went into remission last year and his parents are hoping to raise money to give him his own space and bedroom.
Mrs Takor, 34, told The Sun: 'When I first found out it felt like a massive black hole opened up.
His mother said it was 'very rare' for someone his age because he was placed into the highest risk group.
Writing on his JustGiving page, the music teacher added: 'He had been so amazing and brave and nearly never complained about anything.
'My baby was sick, tired and unwell, but after a tough year where we have gone through chemotherapy, radiotherapy and countless of other secondary treatments, he is now recovering.
Prof Thomas Powles, a testicular cancer expert from London, described Jason's case as being 'one in a billion'.
Mrs Takor, her 35-year-old husband Joshua and Jason's four-year-old sister Sophia received help from children's charity CLIC Sargent and she said she's be 'lost without them'.
