I would tell a newly diagnosed young woman that breast cancer is a complex disease which can be frightening and confusing, and it's normal to experience these emotions, and having a good support system is important. Be an active participant in your treatment, follow your doctor's instructions and ask questions. Also, I would tell her that there have been many advances in breast cancer and women are now living much longer.
I love directing because you get to see your film come to life. You get to work with the actors. There's something magical about each piece of it.
