New research indicates cancer has stem cells

Facing cancer once is daunting enough, but the shock of relapse often leaves a person feeling overwhelmed and depressed. Now three separate studies seem to confirm scientists’ suspicions that so-called cancer stem cells drive the growth and regrowth of tumors. If true, this changes the whole approach to cancer therapy.

Studies are beginning to show tumors contain a small number of cancer stem cells that are often quiescent, shielding them from chemotherapy treatments that normally target and kill tumor cells.
