Worried about a friend

I have a friend who is really freaking out about her health right now. The short version of the story is that she started having headaches, went to the hospital, and they discovered she has a small tumor. The professionals are downplaying it like it is no big deal, but she is really freaking out. I have a feeling it probably isn't terribly serious, but I also worry about how upset she's getting about it. That alone might make it worse.

Anyway, she is in my prayers and if any of you have any words of wisdom for her, I'm sure she'd appreciate it.
