Only a stranger can help save little Margot's life. Could it be you?

A British family of a 16-month-old girl suffering a rare form of blood cancer has launched a worldwide appeal to try to find a stem cell donor who can save her.

Margot was diagnosed just two months ago with a form of leukaemia. Doctors say it is so rare that they have only seen it three times in the past decade.

Margot desperately needs a bone marrow transplant to survive.

For that, she needs a blood stem cell donation from someone who is a match for her tissue type.

Her family is calling on people around the world to take a test that may help them find a perfect stem cell match for their daughter.

This morning, Margot’s parents appeared on Channel 10’s Wake Up.

Many people have asked us how they can help from Australia.
