Fortunately, he caught the disease at an early stage, and he was cancer-free following several surgeries. Last July, Adrian told PEOPLE that thanks to his cancer battle, he was prepared for dealing with the twists and turns of the ongoing coronavirus pandemic, such as the postponement of the 2020 Summer Olympic Games in Tokyo, which he had been preparing for.

"The issue with cancer absolutely prepared me for COVID because it's something that none of us could have truly prepared for," he said. "It just hit us straight in the face. Everything that we know or that we're used to has now been shifted by something that is completely out of control, and cancer kind of taught me that." He added, "2020, all of a sudden [the virus] comes and does it to the entire world. I think I was a little bit more prepared for this than maybe a lot of other people." Adrian is still preparing for the games, which are set to take place in Tokyo this summer.
