As cancer-hating organizations go, the Lance Armstrong Foundation and Livestrong grab a lot of attention. But for active types looking to help raise money or aid people suffering from the disease, another worthy cause is an organization called First Descents.

Launched by pro kayaker Brad Ludden about a decade ago, the Colorado-based nonprofit is committed to "curing young adults of the emotional effects of cancer." This is accomplished via "outdoor adventure therapy" and activities like kayaking and rock climbing.

Since 2000, First Descents has hosted more than 800 young adults with cancer. The organization started as a one-off camp in Vail, Colo., in 2001 with 14 participants. Today, it has grown to 14 programs in six states around the country.

Week-long kayak courses are a mainstay with the organization, which believes in "therapy through kayaking" and the community of people who make up the sport.

This year, the organization has a goal to raise a half-million dollars in the fight against cancer. In 2010, fundraisers and athletes joined "Team FD" to raise about $180,000 for the First Descents program. This year, they hope to up the ante.
