New target in cancer battle: Dividing stem cells

• Terrence Aym
A new discovery has led medical researchers to conclude that stem cells often help spread tumors. Dr. Clive Stanway, chief officer of Cancer Research Technology, asserts that "Stem cells are responsible for renewing tissue in the body. But sometimes they are subverted by cancerous processes. You can give a cancer patient radiotherapy or cut out their tumor surgically—but you can still leave a few affected stem cells behind. The person appears cured. Then the stem cells start dividing again and the tumor reappears."
