Is this a scam? Breast Cancer Society phone solicitation

[ElaineM]

I don't give money to anyone who calls me. There is a federal no call list you can put your number on if you don't want to receive calls from those kinds of people.
I think there is a list of all charities on the internet that even tells us what percentage of the money goes to actually helping people. I would give to the ones that spend most of the money to help people and don't use too much for administrative costs.
