Already in collection, they found 42 tumors in Chondrichthyes species (the class of cartilaginous fish that includes sharks, skates and rays). And if, indeed, they are resistant to cancer, then that makes the study of their immune system all that much more important. A young researcher by the name of Robert Langer decided to repeat the initial rabbit cartilage experiments, except this time using shark cartilage. Peto's Paradox Normally, old and damaged cells are destroyed. This page is not available in other languages. Theory has it that the more the cells in an organism and the longer an organism lives, the more the likelihood of one of its cells succumbing to a random mutation and becoming cancerous.
