The Life Extension Foundation News is reprinting a piece on the work of Thanos Halazonetis: "Cancer is more than 100 different diseases, and what this group has found is a commonality in early stages of development ... Since 1989, scientists have known that [the gene p53] plays a role in the way cells become cancerous ... Halazonetis, 45, argues that there is a way to kill a cell without p53. He said the DNA breaks occur only in cancerous or precancerous cells and therefore can be targeted and forced to die with or without p53's intervention." Early stage identification and prevention of cancer is a big deal - and a cure for cancer is absolutely essential to healthy life extension. A targetted therapy that only killed precancerous cells would be a real breakthrough, and scientists are nearing the point at which they can do this.
