I didn’t look very carefully but didn’t see anywhere that Nancy Brinker and Susan G. Komen were related as sisters.
“Nancy Brinker, founder of the Susan G. Komen Foundation, has served on the advisory board of Planned Parenthood of Dallas. In 2003, Planned Parenthood received a record $475,000 from Susan G. Komen affiliates all across the
nation, and Planned Parenthood of Dallas built a new facility costing $5 million dollars. Nancy Brinker received the Gertrude Shelburne Humanitarian Award from Planned Parenthood of North Texas in 1996. Gertrude Shelburne
established Planned Parenthood in Dallas in 1982, and was a friend of Margaret Sanger, the founder of Planned Parenthood.”
Breast Cancer Prevention Institute is the group I will give all my future support.

Also, Dr. Gerard Nadal has done a lot of work on this issue. He has a blog called Coming Home.
