Many of the colon cancer cells that form tumors can be killed by genetically short-circuiting the cells' ability to absorb a key nutrient, a new study has found. While the findings are encouraging, the test tube study using human colon cancer cells also illustrates the difficulty of defeating these cells, known as cancer stem cells.
