You might begin to wonder which organizations are doing the most in the fight against breast cancer and which are merely opportunistic organizations that are contributing only a small fraction of the funds raised toward the cause with the bulk of the money being absorbed in "administration and fundraising." The latter actually happens more than you think. You can check out most charities at CharityNavigator.org and get a report card of their overall effectiveness.
I decided to go to Charity Navigator myself and pick out some of the site's highest-rated charities in the area of breast cancer awareness, research, and support, so that you can know that your contribution dollars are being used to their greatest effect.
Check them out yourself.
Dana-Farber Cancer Institute

Each of the above organizations were given Charity Navigator's four-star rating, the highest rating the site gives to any nonprofit.
