FWIW - the CharityNavigator linked to by "Smarter than", below, finds at least 22 organizations with "breast cancer" and "awareness" in their names -- all unrated, though many quite legit-looking. (Naturally, THIS one is NOT legit, as the unavailable ID proves...)
Female caller asked for me by name. Caller ID indicated the call originated in Springfield, MA. My wife took the call at 11:47 am. She indicated I was not at home and asked if there was a message. The woman hung up.
We got a call again from this number today at 11:41 am. The caller ID was SPRINGFIELD MA, the same as the last time. This time it was blocked by our call blocker. Please see my post of 23 April 2015.
