Mackenzie “Mighty Mack” Friedman has found her perfect bone marrow donor, and her doctor is confident the transplant can take place in November.


Johannesburg, South Africa (14 October 2021) – The day has arrived that Mighty Mack’s Army has been holding their breath for; she has found a perfect match, and her bone marrow transplant date has been set! All going well, this is the final phase of her cancer battle before the transplant, which is set in November.

We first shared the Mighty Mack Army’s call to get bone marrow donors on the 17th of May 2021. Now all these months later, her perfect match has been confirmed.

Over the last several months, the Mighty Mack Army has rallied through all her highs and lows, donating blood as often as allowed and hosting bone marrow registration drives in the hopes of finding the person who can help her fight off the last of her cancer.

Mackenzie Friedman, affectionately known as Mighty Mack, was diagnosed with Acute Myeloid Leukaemia (AML) on Wednesday, 12th of May 2021; her story has touched the hearts of South Africans and mobilised many to donate blood and register as bone marrow donors in honour of her journey.

She has fought tirelessly, defying odds and giving us all hope through these trying times. Her family have worked hard to focus on every positive, regularly providing updates on social media for all those invested in Mighty Macks treatment. They have been honest in during the hard times too.

This morning they shared the best update about Mack’s treatment, and while she has found her match, they hope that people will continue to register as bone marrow donors and blood donors.

“Our real-life superhero, Dr Nadia Beringer (pictured with Mack above), confirmed yesterday that they’ve found and finalised Mack’s match for transplant, which is now set for 25 November 

This absolute angel of a person (who we have no further details about) is her PERFECT match! This has answered our prayers, and we truly hope that people continue to register as bone marrow donors, so that the prayers of so many other families can be answered too.

Mack will be admitted to hospital on Monday to undergo another week of IV chemo following a bone marrow extraction, and we are hoping that following this she will be able to take a break from chemo prior to the transplant. This is dependent on the results of her bone marrow extraction next week.

We still have a long road ahead but will continue to focus on the positives, and a 10/10 match, with a donor who is keen to start the process, is a huge win for us all, and a massive step to leaving this cancer journey behind us.”
