Mapping Africa’s DNA: The Cancer Genomics Revolution

By Tobbias Mutunga

The Common Pulse | August 2025

For too long, global cancer research has overlooked one key variable: Africa. Despite being home to over a billion people, the continent’s genetic diversity has been vastly underrepresented in genomic studies, leaving gaps in diagnosis, treatment, and drug development. A bold project in Ghana is now changing that story.

Yemaachi Biotech and the Vision for an African Cancer Atlas

Founded by Ghanaian immunologist Dr. Yaw Bediako, Yemaachi Biotech is building what will become Africa’s largest cancer genomic database. The goal? To collect and analyze genetic information from up to 7,500 cancer patients across the continent.

This initiative, backed by global pharmaceutical giant Roche, is more than just a data project. It’s about rewriting the future of cancer care for African populations, and by extension, for the world.

Why Genomics Matters in Cancer Care

Cancer is not a one-size-fits-all disease. Tumors behave differently depending on genetic backgrounds, and treatments developed in Europe or North America may not work as effectively in African patients. Without representation in research, African communities face misdiagnosis, late detection, and limited therapeutic options.

The African Cancer Atlas will help close that gap by:

Identifying unique genetic markers of cancers prevalent in Africa.
Accelerating drug discovery tailored to African patients.
Improving pediatric cancer care, where survival rates remain tragically low.
Boosting global diversity in research, creating more inclusive medicine.

A Global Resource Born in Africa

Yemaachi’s work isn’t just for Africa. By adding African genomic data to the global pool, the project ensures that medical discoveries benefit everyone. After all, Africa holds the greatest human genetic diversity on the planet. Insights gained here could unlock breakthroughs for cancer treatment worldwide.

Challenges and Opportunities

Collecting genetic data across multiple countries involves navigating issues of infrastructure, data privacy, and equitable access to results. But with strong backing, a clear mission, and growing international partnerships, Yemaachi is positioning Africa as a global leader in precision medicine.

Looking Ahead

If successful, the African Cancer Atlas will do more than improve health outcomes. It will signal a shift in how the world views African science, not as a peripheral player, but as a driver of groundbreaking discovery.

As Dr. Bediako himself often emphasizes, “We are not just consumers of science. We are producers.”

The future of cancer care may well depend on Africa’s DNA.

Utah Man, 22, Charged in Killing of Conservative Activist Charlie Kirk

By Kiranagacha Mwaniki - The Common Pulse - Orem, Utah ; September 13, 2025 The bustling quad of Utah Valley University was supposed to be a stage for debate and free expression. Instead, it became the scene of political violence that has shocked the nation. Charlie Kirk, 31, a conservative activist and co-founder of Turning Point USA, was fatally shot on September 10 while addressing students at a “Prove Me Wrong” debate. Authorities say the shots came from a nearby rooftop, fired by a young man who had quietly prepared for weeks. On Friday, Utah County officials announced that Tyler James Robinson, 22 , had been taken into custody and charged in connection with Kirk’s killing. He is being held without bail at the Utah County Jail. From Apprentice to Accused Killer Robinson grew up in Washington County, Utah, in what neighbors describe as a quiet household. He worked as an electrical apprentice and once attended Utah State University for a semester in 2021. “He was always ...

No Exit: Biya’s Return, Democracy’s Decline

By Kirangacha Mwaniki The Common Pulse | August 2025 At 92 years old, Cameroonian President Paul Biya has signaled his intention to run for yet another term in the 2025 presidential election. Having ruled since 1982, Biya is now the second-longest-serving head of state in the world; after Equatorial Guinea’s Teodoro Obiang. His decision has sparked outrage, resignation, and confusion among Cameroonians, many of whom have never known another leader. This re-election bid is more than just a political event; it is a glaring symptom of a system that has resisted reform, ignored generational change, and weaponized fear to maintain the status quo. The Man Who Time Forgot Paul Biya came to power before most Cameroonians were born. He has led through the Cold War, the rise of mobile phones, the internet revolution, and the African Continental Free Trade Area — all while aging behind the walls of Etoudi Palace. He is rarely seen in public, often ruling from abroad; mostly Swit...

A Fiery Afternoon in Mwihoko On the afternoon of Thursday, August 7, 2025, tranquility in Mwihoko, Githurai 45, an otherwise peaceful residential area, was shattered. A light aircraft plummeted into homes, igniting massive flames and causing widespread panic among residents. Eyewitnesses reported screams from those trapped inside structures as fire engulfed walls and rooftops. ( Nairobi Leo , Kahawa Tungu ) Community Rescues Amid Chaos In a race against time and rising flames, local residents grabbed whatever they could; buckets, garden hoses, shovels, to help douse the blaze while waiting desperately for official help. Their efforts were a testament to bravery and communal spirit as neighbors pulled each other ...
