A nine-month-old boy is fighting a rare form of testicular cancer after his parents found a lump in his scrotum.
Freddie Burgess-Shardlow has an ectomesenchymoma, a rare and fast-growing tumour of the nervous system or soft tissue.
Emma Burgess, 36, said she and partner Katie Woodward, 34, first found a lump in their son's testicles in March.
The pair took their son to the doctors straight away, with medics initially believing it was a sign of a hernia - common in babies.

Ms Burgess and Ms Woodward claim they noticed his lump had grown 'quite a bit' while in Gran Canaria in May on holiday.
However, Ms Burgess, a sales worker, said the couple 'just put it down to the cabin pressure on the plane'.
When they returned home, Freddie was taken to the Pilgrim Hospital in Boston - his parents were working nearby in Skegness.
Ms Burgess said doctors told them it was an abnormal growth after being referred to the Queen's Medical Centre in Nottingham.
'They said it was a hydrocele and told us if it had not gone down by the time he was 18-months-old to come back for a check-up,' she said.
A hydrocele is a type of swelling in the scrotum considered common in newborns. It occurs when fluid surrounds the testicle.
