Many varieties of cancer, including breast cancer, begin inside stem cells, Texas A&M University researchers Weston Porter and Clinton Allred say. By understanding how stem cells regulate their own growth, researchers may develop a method that shuts down out-of-control cells, and keep tumors from spreading. This approach could even prevent cancer all together. By combining traditional therapy that shrinks tumors with new therapies that target malfunctions within stem cells, medicine may manage cancer far more effectively in the near future.
