Whales don't get cancer as often as you might expect, and in this episode you learn how the bowhead whale's unique DNA repair system is helping scientists understand cancer prevention and healthy aging. This Arctic giant lives more than 200 years, grows to airplane size, and still avoids the runaway mutation patterns that lead to tumors in other species.

Whales don't get cancer at high rates because their cells repair DNA damage with remarkable accuracy, and recent studies show that bowhead whales have powerful repair proteins like CIRBP that might someday guide cancer research. You will hear how this repair strategy works, why it matters for humans, and why protecting long-lived marine mammals also protects the scientific insights they carry.
