Naked Mole-Rats Don’t Get Cancer: The Metabolic Trade-Off That Broke the Longevity Narrative

STAT News reported that naked mole-rats (Heterocephalus glaber) exhibit extraordinary cancer resistance due to high-molecular-weight hyaluronan (HMW-HA). The claim is correct, but the metabolic cost of HMW-HA synthesis is the elephant in the room: it accelerates cellular senescence, shortens maximum lifespan, and may explain why these rodents live 8x longer in captivity but suffer rapid aging in the wild. This isn’t a longevity breakthrough—it’s a trade-off between cancer suppression and tissue integrity.
