Participants unite for the annual American Cancer Society Relay For Life Night to celebrate people who have been touched by cancer, remember loved ones lost, and take action for lifesaving change.

Funds raised help the American Cancer Society attack cancer in dozens of ways, each of them critical to achieving a world without cancer – from developing breakthrough therapies to building supportive communities, from providing empowering resources to deploying activists to raise awareness.

The Relay For Life movement is the world’s largest peer-to-peer fundraising event to save lives from cancer. The two in our area are:
