Diggester writes: New research, which consists of three independent studies, shows that tumors are fueled by cancer stem cells. Stem cells are biological cells that can divide and differentiate to into specialized cell types and can self-renew to make more stem cells. So in the case of this discover of cancer stem cells, if their gone then nothing can multiple and infect the body. Now the medical community just needs to find a way to isolate these cells and get rid of them before the spread starts, whether that be through vaccine or surgery, and it could potentially extend the life as we know it.
