Lance Armstrong

Lance Armstrong is well known for his battle with testicular cancer in 1996 and was given a 2% chance of surviving the cancer. This is because it had spread to his brain, lungs, and abdomen.
Not only did Armstrong beat the odds and successfully enter remission but he also won the Tour de France not once, but, seven times since having a 98% chance of succumbing to cancer. [Testicular cancer cure]
Although he retired in 2005 from competitive bicycling it seems he cannot keep away as he returned to the sport in January of 2009.
