Betterhumans reports on recent research that provides another insight into the genetic links between cancer and aging. A longevity gene essential for tissue repair is also essential to cancer, or so it seems. This initial study suggests that removing the gene in mice prevents tumors from developing (but no doubt has undesirable effects on healthy life span). That should get you all thinking, but here's some speculation from the scientist involved: "Perhaps aging is just an unintended byproduct of an adaptive mechanism to stave off cancer and certain death. Perhaps aging is just nature's way of attacking cancer."
