So it's a fundraiser...where does the money actually go?

Relay funds 4 segments of the American Cancer Society, Research* being one of them. I stumbled across the update below today--donation dollars in action!

Targeted Drugs, Vaccines Among Cancer Advances in 2006
The Year in Review

* Research: The American Cancer Society is the nation’s largest non-governmental organization to fund cancer research. The Society funds the most innovative, groundbreaking research so future generations won’t have to face cancer as a life-threatening disease. Society researchers have won 40 Nobel Prizes and our research program has helped save millions of lives.

To date, the American Cancer Society has spent more than $2.5 billion on research. That research has led to advances such as the Pap test, the bone marrow transplant, and drugs such as Tamoxifen and Gleevec, which have positively impacted and even saved the lives of many people with cancer.
