The 31-year-old has been in remission for the past four years thanks to early detection, which saved his life considering the cancer had spread to his lymph nodes.
And now his goal is to prevent the rest of the male population from letting testicular cancer go unnoticed before it’s too late.
“There aren’t very many young men advocates that are coming in with a little bit of an edge,” Mr Cantley told A+.
“A lot of them are older. I kind of wanted to hit the demographic. I’ve been doing it for a couple years, but I realised I needed to get out there more.”
He’s accomplishing that by pushing a 6-foot inflatable testicle, which people can write notes on, from California all the way to New York. He started his journey in Santa Monica on September 3.
The project is called Ball Push, and Cantley will travel through eleven cities where he’ll meet fellow survivors he connected with online and recruit new members to Mr Ballsy, his support group.
Cantley says he wants the most commonly diagnosed demographic — 13-to 35-year-old men — not only to have routine check-ups but also not to feel alone should they test positive.
“When I was diagnosed, I didn’t want to talk about it, I pushed everyone out of life.”
Cantley has been given hotel rooms and food on his journey but has turned down every monetary offer because it’s not MONEY that allowed him to beat cancer.
The only help he wants in completing the journey, he said, is the service of other people.
And for those who are wondering, the ball is named Lefty, after the testicle he lost.
