Breast cancer screening and treatment, especially in younger women

[Editor's note: I was on Twitter, as usual, a couple of days ago, and started seeing tweets with the hashtag #SSCAbc.

I've aggregated some of those tweets below, but you can read more at the hashtag here, which represents the Seattle Cancer Care Alliance, whose representatives were conducting the Twitter session.]
