Active men are the least likely to check for signs of testicular cancer despite being just as likely to get the disease. We turned something active men were doing already into a way to check for cancer. GRAB YOUR ROCKS is the world’s first rock climbing wall that teaches men how to check for signs of cancer. We made custom ball shaped rock climbing hand holds that simulate symptoms of testicular cancer and took over a climbing gym. As men climbed the walls, they learned how and what to check for.
