LIMA, Peru - Five-time Olympic gold medalist Nathan Adrian of the US says his success won't be on his mind at the end of his life.

Maybe that would have been him some years ago. But not now, not since his latest race.

This time, it's to beat cancer.

"It has completely changed my outlook. At the end of my time on Earth, whenever that may be, I don't think the first thing on my mind is going to be how many gold medals I've won," Adrian told Associated Press before his first race at the ongoing Pan American Games in Lima.

"I'm actually very confident of that, whereas you know, maybe five or six years ago, my answer might've changed a little bit," said Adrian. "So, my priorities are still competing and achieving at the highest level, certainly. But to take a deep breath, or to try to enjoy the company of those around me, that's something that I'm trying to be aware of as much as possible."

Adrian was diagnosed with testicular cancer in December.

"My reaction was probably what most people experience, a little bit of everything, you know - being scared, being a little bit angry, just questioning why? Like wondering if I had called my mom enough," he said with a smile.

"All sorts of things, and it was just like a roller coaster, like I couldn't really control it, so I just kind of let it happen."

Doctors told him the cancer had been caught early and he begun treatment. A month later, he underwent surgery, and decided to continue to train for the Tokyo 2020 Olympics.

The 30-year-old earned silver in the 4x100m medley relay at the recent world championships in Gwangju, South Korea. It felt like victory for Adrian, who was competing just months after the cancer diagnosis.

"I'm still in the process of conquering it," he said. "Between a couple of surgeries, treatment and ongoing surveillance, here we are, a little more than six months later, and I just feel fortunate to compete."

The 30-year-old said he's also looking forward to his first Pan American Games.

"I feel good. I left the worlds about a week ago, and then we're here to compete again. I've never been to a Pan American Games so it's really cool," Adrian said near the tournament's pool.

"It's a mini Olympics, so it's a really a very special feeling."

At the 2012 Olympics, Adrian won the 100m freestyle. Four years later, he earned bronze in Rio de Janeiro. He has four other Olympic gold medals as part of US relay teams.

Adrian has been swimming since the age of 2, and competitively, since the age of 5.

The decision to get back in the pool had the backing of his loved ones, including his wife, Hallie Ivester, his parents, Jim and Cecilia Adrian, and his siblings, Donella and Justin, who also swam competitively.

Everyone is rooting for him back in his hometown of Bremerton, Washington, where a street was named after him.

"I think my family knew how important it was for me to get back to competing just for my own mental and emotional health," he said.

"I think for anybody who goes through an adverse health condition, the quicker you can get back to what makes you feel normal, what makes you feel good, the better."

The process has been "really tough", he said. "You get diagnosed, and then you don't really know or have any information besides that you have cancer."

He said the wait seems long until the scans are read because sometimes doctors are backed up.

"And it's tough mentally and emotionally, because you're like, 'Man, maybe this is spread, or maybe we caught it early?'"

Endurance is everything to a swimmer. But Adrian said he's been in touch online with others who endured the same things he has outside of the pool.

"A lot of my messaging to this point has been for men out there: If you feel that something is going on, you have to go see a doctor," he said.

"A lot of guys wait. They feel something going on there, and then they wait until their treatment options are a little narrower and the prognosis isn't quite as good. But if they get in there early, and early detection is key, hopefully everyone can live a little bit longer."

As in any race, his goal is to beat cancer as quickly as possible. His other goals are also clear.

"In the future? Of course Tokyo 2020," he said.

"And then for life - probably spending a little more time at home with my wife and a little less time on the road training and competing, once this is all over."
