For many of the tumors now, we're able to give, what we call, targeted therapy. These are pills that are designed specifically to target the tumor cells and not the normal cells. Therefore, the side effects are much less, and these pills work much better.
In many cancers today, we are doing this routinely. Certainly, breast cancer is an example, where we have the only laboratory that is able to test for certain proteins on the surface of the breast cancer cells, and that evaluation leads to specific treatment decisions that affect women every day here in Rochester.
