Please leave your answers to the question "What is breast cancer?" in the Comments box below.
Feel free to be as technical or as poetic as you like.
I'm reminded of Older Son's question shortly after he found out that I had breast cancer (he was 13 at the time). He asked me (paraphrasing here, this was a long time ago) How can (or does) breast cancer hurt you?
You know, I was stumped. I did not know the answer. I asked my oncologist to explain at my next appointment. Then I explained to my wise child.
