Ethnic diversity crucial in blood stem cell donations─── ZENANDE MPAME 14:34 Wed, 05 Feb 2025
A diverse donor registry is essential to ensure that every blood cancer or blood disorder patient can find a compatible stem cell match.
Finding a genetic match is critical for a patient’s survival, yet it remains incredibly rare – especially for black and coloured patients.
DKMS, an international non-profit fighting blood cancer, aims to match patients with donors worldwide.
“An ethnically diverse donor pool gives patients from different backgrounds a better chance of finding a compatible match,” said DKMS Africa’s Palesa Mokomele.
“Stem cell matches are based on genetic markers found in a person’s DNA. A black patient is more likely to find a match within the black donor pool, just as a white patient is more likely to match with a white donor.”
World Cancer Day is observed annually on 4 February. This year’s theme, United by Unique, highlights that every cancer experience is different and that each person has unique needs and perspectives.
Symptoms of blood cancer include:
- Unexplained weight loss, bruising, or bleeding.
- Persistent fatigue and fever.
- Bone and joint pain.
- Lumps, swelling, or skin changes.
- Shortness of breath and night sweats.
- Frequent infections.
- Abdominal issues.
- Neurological symptoms.

Blood donation vs. stem cell donation
Unlike blood donations, stem cell donations only occur when a registered donor is matched with a patient.
“You only get called to donate after registering with DKMS Africa and being confirmed as a match,” said Mokomele. “This differs from blood donation, where people donate regularly to help save lives.”
