And I literally didn't know what to say or how to react. All I could do was tell her to please take good care of herself and ask her about treatment. She sarcastically said "what treatment?" I feel absolutely horrible and scared for her. She is nearly 50 years old and therefore is in a vulnerable age bracket. Her health is generally pretty good, but still, I am very worried.

And I feel badly because I don't think I said the right things to her. I was out of words, and she is one of my oldest and closest college friends.
