"Too many families in this situation face the awful news that there is no matching donor on the stem cell register, which is why I am supporting Match4Maggie, a very important campaign to increase the number of potential donors."
She continued: "I am asking everybody aged 16 to 30 who is in general good health to sign up. It could literally be the difference between life and death for Maggie and other people in her situation. Her story shows just how much stem cell donors are needed and I am praying they find the perfect match for her soon.

"In the meantime, I am sending love and strength to Maggie and her family – let's get her back on her surfboard. I ask everyone to spread the word about the campaign."
For her treatment, Maggie requires stem cells from anybody aged between 16 and 30 who is a match for her.
