Teenager Tabitha Wood, battling a rare ovarian cancer at just 13, had fought to stay stoic even as the surgeons removed a tumour the size of a melon.

There's no point worrying, she says, about the things you cannot change. Better to balance what can be done, in easing the everyday battle.
Two years on and now in remission, Tabitha has helped to raise nearly £23,000 to thank those those that saved her life.
Every penny, she hopes, could make the cancer battle less harrowing for others.
"What I went through was quite sad, I didn't want other people to feel like that," says the now 15-year-old Bradford Grammar School student, from Burley-in-Wharfedale.
"I thought if I could help, that would be really nice.
"Cancer is the last thing you think about, until it happens," she adds. "I didn't think it could be anything that serious, I didn't feel that bad."
Diagnosis and treatment
In Autumn 2017, Tabitha had started to feel unwell. Already slight, she was losing weight, and becoming very pale.
Feeling a lump in her stomach, her parents had taken her to the GP and she was referred for blood tests at Leeds General Infirmary.
"I thought it would just go away," she said. "They knew it was cancer from the first day. The doctor came and sat with me, they said 'I'm sorry but this is what it is'."
The ovarian cancer that Tabitha had is very rare in the UK, with only around 40 cases diagnosed every year.
Her parents, Sarah and Adrian Wood, had approached the world leader in this field, Prof Seckl in London, to work with oncologists at LGI over Tabitha's care.
Diagnosed within days, doctors were able to operate immediately. They removed a grade-three tumour so large it was the same size as a 20-week baby, growing inside her.
Strength and resilience
Today, Tabitha grins as she recalls how excited the surgeons were, taking pictures of the mass, with two hospitals fighting over the right to research it further.
"They didn't make it seem as if I were really ill," says Tabitha. "I didn't think about what could happen, just what was happening really.
"I tried not to worry too much about it, because you can't really help it."
She's always been incredibly practical over what was happening, says her mother Sarah Wood, 50.
"Tabby is so resilient," adds Mrs Wood. "She just gets on with it, no matter what happened she just dealt with it.
"She's very stoic, never complaining, never wanting anything to be different.
"She could have taken a year out of school, she hasn't. She could have dropped subjects, she hasn't. She's just kept on, and keeps keeping on."
Tabitha is now in remission, though there is a 25 per cent chance the cancer will return and she has regular scans and tests.
But, a keen rider who competes in dressage and who has ridden for England, she feels fighting fit and wants to give a little back.
Having met with her consultants to see how she could help others on the teenage cancer ward at LGI, Tabitha set herself a fundraising challenge.
While a sponsored bike ride may seem a drop in the ocean against NHS reserves, the family has smashed all targets, raising nearly £23,000.
Tabitha, who hadn't really ridden a bike until July, was accompanied by her father and brother Ben, 19, on the 240 mile ride over the course of six days.
They were seen off from Charing Cross Hospital by Prof Seckl, and met by consultants at LGI. With donations, Tabitha hopes to buy a new television for inside the MRI machine on the teenage cancer ward, and she has just been shortlisted in two separate categories of the Bradford Community Stars awards
"It's been quite overwhelming, the support," adds Mrs Wood. "But there's a really big reason behind it.
"I've never seen Tabitha so animated as when she knew that she could do something to make others' lives a bit better when they are having such a difficult time."
