Call came on July 1, 2015, at 2:18 PM MDT.  No name on caller ID.  Female caller asked for me by name.  When I acknowledged my name, there was a pause, and it sounded like she connected me to a recording.  It was regarding cancer research.  I hung up.  Years ago I donated some money to breast cancer research when a college student living next door to me was collecting, in person, for such an organization.  Now I get phone calls from cancer research organizations, year after year, but not always from the same number.  I do not respond to requests for donations over the phone from any organization, but particularly not cancer research, because I recently read an article that said less than 20% donated to cancer research actually goes toward research.
