How AI is transforming medicine, and the cancer fight
In 1971, President Nixon declared a “War on Cancer.” Fifty years and billions in research later, the disease still kills 1,700 Americans a day—and survival often depends on income, race, and access to care. But could artificial intelligence finally give humanity the upper hand?
On the latest episode of GZERO World, Ian Bremmer sits down with cancer researcher and bestselling author Siddhartha Mukherjee to explore how AI is changing the trajectory of modern medicine. From early detection and diagnostics to drug discovery and personalized treatment, Mukherjee believes we're entering a new era in the fight against cancer.
“The machine learns it, and it learns it forever,” Mukherjee says, describing how AI can now generate new chemical compounds that have never existed—potentially designing cancer drugs from scratch. “You don’t need to train a new generation of chemists. The machine will now learn it for eternity.”
Mukherjee explains how this generative power can unlock faster, cheaper breakthroughs across all stages of cancer treatment—from identifying new carcinogens like “forever chemicals” to tailoring therapies to a patient’s specific biology. For a disease that touches almost every family, these advances aren’t just technological—they’re deeply personal.

50 years of the war on cancer
We've been fighting a war on cancer for over half a century—from Nixon’s 1971 National Cancer Act to the promise of cutting-edge AI therapies today. Ian Bremmer reflects on how that war is going.
The numbers are still grim: nearly 1 in 2 men and 1 in 3 women in the US will be diagnosed with cancer, and 1,700 people die from it every day. Disparities persist—Black women are 40% more likely to die of breast cancer than white women—and treatment costs remain crushing for many.
But there’s progress. Survival rates have more than doubled since the 1960s, and new technologies, especially AI, are opening doors researchers couldn’t imagine a decade ago. For Ian, it’s personal. Both of his parents died of cancer. “If you haven’t had it yourself,” he says, “you know someone who has.” But for the first time in decades, there’s real hope that science may be gaining the upper hand.
