These stem cells, just one type of cell found throughout cancerous tumors, promote tumor growth as well as the spread of cancer within the body. Cancer stem cells have also shown the ability to be resistant to chemotherapy and radiation therapy. "So radiation and chemotherapy not only might create cancer stem cells, any pre-existing cancer stem cells in a tumor were very resistant to radiation and chemotherapy, so they remain as well," says Dr. Chiang Li of Harvard Medical School. "This could help explain why these therapies are sometimes not as effective as we might hope."

This increases the ratio of stem cells to non-stem cells. As a result, tum...
