1. Elephants
Despite their enormous bodies and long lives, elephants rarely develop cancer. Their secret lies in an abundance of TP53 genes—they have about 20 copies, compared to just one in humans. These genes are crucial for identifying and repairing damaged DNA or destroying cells that could become cancerous.
This natural safeguard helps explain their low cancer rates and has captured the attention of scientists. Research into elephant genetics could inspire more effective cancer prevention strategies for humans.
