In the ancient sport of dragon boat racing, an unexpected group of athletes has emerged - breast cancer survivors. But this is no ordinary race. It's a challenge to the medical wisdom that repetitive upper body motion, like paddling, could cause a condition called lymphedema.

Dr. Susan Harris and Dr. Don McKenzie, two pioneers in the field of exercise and lymphedema, have recruited two dozen women to paddle with them and challenge the myth.

With no studies to prove the connection between exercise and lymphedema, they took a bold step and started training for the dragon boat race. Will they be able to prove the naysayers wrong and show the world what breast cancer survivors are truly capable of?
