Every 15 minutes, 50 Americans are diagnosed with cancer. This is a sobering reality. But, the good news is that every year millions of Americans are beating cancer through advancements in treatments. Swim Across America, the official charity for swimmers, exists to raise money for our network of doctors and researchers who are the pioneers developing new cures and treatments to this dreaded disease. Michael Phelps and over 100 Olympians support SAA.
