For near on two years, the Mighty Mack Army has watched and rallied as Mackenzie Friedman has fought and overcome her cancer thanks to an anonymous bone marrow donor; today one of those supporters has potentially matched to help save another life.
Johannesburg, South Africa (29 March 2023) – Mackenzie “Mighty Mack” Friedman has inspired thousands of people to register as bone marrow/stem cell donors. Her story started making headlines in May 2021 after she was diagnosed with Acute Myeloid Leukaemia (AML). Her aunts Amy Stanton and Nikita Friedman created the Mighty Mack social pages and the Mighty Mack Army was born.
Through consistent updates about Mack’s illness, her need for blood donors and eventually, bone marrow donors, thousands of Mighty Mack Army supporters signed up in the hopes of helping. Her story grew and she began to feel like family to many.
All of Mack’s family signed up to be donors when the time came, in the hopes of being her much-needed match. Sadly, nobody did match and so the search for an anonymous donor outside the family began. By October 2021, Mackenzie had found her match and the process began for her to have the lifesaving transplant.
Even though she eventually found her match, the family has continued to advocate for blood and bone marrow donors. Throughout Mackenzie’s battle, her parents Megan and Bronson, connected with other families going through the same struggles. It is for them and every child undergoing treatment of blood cancers and disorders, that they continue to raise awareness today.
Having one of the Mighty Mack Army supporters get that all-important notice of being a potential match, truly warms the heart! And you could be next! If you are eligible, you can become a donor using the details below.
As for updates on Mackenzie, they are still taking place each week on Facebook. You can follow along here. She is in the middle of a brief bout of chemo before another small transplant to get her 93% donor cells up to 100% but she is still cancer free.
