Just two years ago Komen for the Cure founder Nancy Brinker wrote in her memoir that Planned Parenthood helped "rural women, poor women, Native American women, many women of color who were underserved" and that not supporting those centers would be turning "our backs on these women."

Brinker publishing those statement in her own book illustrate an understanding of how a decision to cut funding for breast cancer services could affect poor women.

In 2010, Komen founder and Nancy Brinker published "Promise Me", a memoir of how the group was founded and grew, starting from the deathbed promise made to her sister, Susan G. Komen, who died of breast cancer in 1980.

In the book, she discusses how the Curves workout chain withdrew their support to Komen in 2004 due to Komen’s grants to Planned Parenthood centers. Brinker is clear about why they refused to buckle to Curves’ pressure: 

 "The grants in question supplied breast health counseling, screening, and treatment to rural women, poor women, Native American women, many women of color who were underserved–if served at all–in areas where Planned Parenthood facilities were often the only infrastructure available. Though it meant losing corporate money from Curves, we were not about to turn our backs on these women."

Several sources have claimed the person behind the new regulations that attempted to block grants from Planned Parenthood is the new Vice President for Public Policy Karen Handel. Earlier today a source working close to top executives at Komen alleged "Karen Handel was the prime instigator of this effort, and she herself personally came up with investigation criteria" to sever ties with Planned Parenthood.
