Cancer is defiant. So we're going to defy it. It's persistent. So we have to persevere. It's discouraging. So we must have courage. We are the LIVESTRONG Challenge - uniting people to pick a fight with cancer and to stand up for the nearly 12 million Americans living with cancer today.

Cancer doesn't discriminate, and neither do we. Whether you walk, run, ride, volunteer or donate, your participation is one more powerful weapon in the crucial fight against cancer.
