Stem cell findings point toward new cancer treatments

Three studies on different types of cancers bolster the theory that specific stem cells within tumors are responsible for a cancer's persistent growth.

Scientists hope that if drugs are designed to kill or disable "cancer stem cells" like this one, they could eradicate the tumor. (UCLA / August 1, 2012)
When cancers are treated, tumors may shrink but then come roaring back. Now studies on three different types of tumors suggest a key reason why: The cancers are fueled by stem cells that chemotherapy drugs don't kill.
