Doctors gave Sean Swarner two death sentences, but now he’s on top of the world.

The two-time cancer survivor only has one functioning lung, and 15 years after doctors gave him two weeks to live, he climbed the highest mountain in the world, Mt. Everest. 

He talked to Growing Bolder about his latest efforts to scale Alaska’s Mt. McKinley and how he helps other cancer survivors fulfill their dreams through his group, the Cancer Climber Association.
