Sean Swarner: first cancer survivor to complete the 7-summits, the highest peaks of the 7 continents
Sean isn't just a cancer survivor; he is truly a medical marvel. He is the only person in the world ever to have been diagnosed with both Hodgkin's disease and Askin's sarcoma. He was diagnosed in the fourth and final stage of Hodgkin's disease at the age of thirteen, when doctors expected him to live for no more than three months. He overcame his illness only to be stricken a second time when a deadly golf ball-sized tumor attacked his right lung. After removal of the Askin's tumor, Sean was expected to live for less than two weeks. A decade later and with only partial use of his lungs, Sean became famous for being the first cancer survivor to climb Mount Everest.
After the summit of Everest, Sean had the desire and dream to continue moving forward and reaching people around the world. Climbing the highest mountain on each continent became his next goal. Proving to others that anything is possible, Sean successfully summited Mt. McKinley, to be the first cancer survivor to complete the seven summits. You can read more about Swarner's story on his 2007 book.
