Leukaemia: The teen helping children through cancer treatment

Those activities have involved documenting her cancer journey on TikTok to more than 35,000 followers, as well as helping to raise money for the hospital’s charity arm.

Her newfound confidence has also led her to take on a “big sister” role to many younger patients on the ward, whom she describes as “one big family”.

“A year ago if I had to come into hospital I’d be absolutely petrified, but now the ward and the whole hospital feels like a home,” said Mia.

“All the little kids on the ward are going through the same thing, so I try and show them the procedures.

“I think seeing a role model like me who is going through the same thing helps them feel a little bit less scared.”

Having found unexpected social media fame, she is determined to use her platform for good.

“It sort of blew up so I thought why not raise awareness and money for the charities, especially Noah’s Ark who have been a help to me since my diagnosis,” said Mia, who has already raised over £2,000.
