A 17-year-old with terminal cancer will marry her school sweetheart in a whirlwind wedding organised by friends, family - and strangers.

Amber Snailham, from Bishopsworth, Bristol, is set to tie the knot to first love Callum Firth later this month surrounded by loved ones.

It comes after doctors gave her the heartbreaking news last Friday that cancer discovered in her diaphragm has spread to her brain and she was given a terminal diagnosis.

Amber Snailham was given a terminal diagnosis on Friday and upon hearing the news her high school boyfriend Callum Firth (pictured with Amber) popped the question after learning getting married was on her bucket list

In spite of the devastating diagnosis, Callum got down on one knee after learning that getting married is at the top of Amber's bucket list.

The loved-up couple - who met at Bedminster Down School and have been dating for a year - have now set about organising the perfect big day.

Both families and the youngsters' pals are organising a huge wedding and have fixed a date for the ceremony - November 25.

As well as friends and family rallying together to help Amber's dying wish come true strangers have been donating money towards her wedding fund.

Amber's mother Joanne Snailham said: 'There are lots of people helping, the support from everyone has been just unbelievable.

'It's absolutely hectic getting everything organised, especially given the short time we've given ourselves before the wedding.

Thanks to the kind donations of strangers and the help of friends and family the pair will wed on November 25

'The consultants gave her the diagnosis on Friday, and we got cracking on this over the weekend.'

On Wednesday, Amber picked out the perfect wedding dress at the A Class Brides boutique after owner Nicky Williams shut up shop to give them her full attention.

On Thursday Amber was set to undergo potentially life-lengthening surgery at Bristol Children's Hospital to remove as much of the tumour as possible.

It has been a rollercoaster for the teen since she was first diagnosed with a saracoma of the left femur - bone cancer in her leg - four years ago, when she was just 13.

Joanne said: 'She had a year of chemotherapy, and when she was 15, she went into remission for two and a half years.'

But just before Christmas last year, she began to feel unwell again.

Joanne continued: 'She started feeling poorly, and we were obviously straight back to the doctors.

'On New Year's Day this year, we were told she had relapsed, and the cancer had returned, this time to her diaphragm'.

Amber has been treated at the adolescent and oncology wards at Bristol Children's Hospital with the support of her family and, this time, with the love of her life Callum.

It's mixed emotions for everyone. - Joanne, Amber's mother

She underwent a big operation and underwent a further six months of chemo, which finished in July.

But last week, she was given the devastating diagnosis that there was now a tumour in her brain.

Planning the wedding of her dreams is now the family's focus.

Joanne said: 'It's mixed emotions for everyone. We've had this totally devastating news, the worst thing anyone could ever possibly hear.

'But we're determined to make the wedding happy and we are focusing on that.'
