New evidence from three independent studies supports the idea that solid tumors in the brain, colon and skin can arise from a few bad cells known as cancer stem cells.

Cancer researchers have debated whether every cell in a tumor is capable of re-creating the tumor, or if only a few special cells have that capacity. To answer the question, researchers have transplanted tumor cells from human cancers into mice, producing mixed results.

Now, in separate attempts to settle the issue, three re...
