E don't think there's any more disease where you become more involved in a patient's life in cancer.

You know about their family.

You know about what they want and what they don't want.

And that's really gratifying.

How I picked breast cancer was we were starting to understand that certain proteins regulated breast cancer cell biology.

And if we understood more about those proteins that we do a better job of treating disease, the idea that can't yourself from your longer from your colon are from a woman's brass door for man's prostate can leave and go elsewhere is really a very substantial kind of cell trick, if you will, that needs to be understood.

Understanding how things function lead you to better outcomes.

And that's been the story for cancer biology.
