According to AAP, Madeleine Riewoldt, 26, suffered from aplastic anaemia, a condition in which bone marrow does not produce sufficient amounts of blood cells.
“After a five-year battle, two bone marrow transplants and seven months in hospital fighting aplastic anaemia, Madeleine Riewoldt, 26, couldn’t fight any longer,” the Riewoldt family said in statement.
“Her incredibly brave battle ended this morning at Royal Melbourne Hospital with family — Mum Fiona, Dad Joe, brothers Nick and Alex, sister-in-law Catherine and nephew James by her side.
“We are so proud of Madeleine for fighting as long and hard as she did.
“This spirit is a testament to her strength, she inspired us and so many and will continue to do so.
“We are grateful for and cherish the 26 years we shared as a family and she will remain in our hearts always.”
The family went on to thank Royal Melbourne Hospital staff and asked for privacy.
