Rare Stem Cells Appear To Drive Cancers, Science News
 









Excerpts: Why are many brain tumors and other cancers so difficult to treat?

For decades, cancer researchers have wrestled with two competing visions of
tumors. In one scenario, all the cells of a tumor are pretty much the same. That
is, they have an equal capacity to divide and form new tumors.

 In the other scenario, only a few select cells from a tumor have the capacity
to initiate new, full-fledged tumors. These bad seeds are the cancer stem cells.
