The AACR Philadelphia Marathon on Sunday raises awareness and financial support for the non-profit thanks to the Fundraisers, the AACR staff and of course the Runners for Research. The American Association for Cancer Research is committed to cancer research, administering grants, and finding cures for all types of cancers. It is the oldest and largest scientific organization in the world focusing on cancer research. The AACR is located right here in our hometown in Philadelphia at 615 Chestnut Street.
