Nate Solder was diagnosed with testicular cancer before the 2014 season in April.
Doctors determined the cancer hadn't spread and were able to remove the testicle.
Solder went on to start every game of the 2014 season protecting Tom Brady's blindside.
"I knew nothing about it. It was a complete surprise," said Solder, who turned 27 on April 12 and enters his fifth NFL season in 2015. "You Google something like that and it kind of scares you, so I was like, 'I'm not going to freak out about this.' Had I not had a routine physical, I probably wouldn't have checked it, saying, 'Oh, it's just in my head, I'm going to be fine.'"
According to the American Cancer Society, testicular cancer can develop in males of any age, including infants and elderly men. Almost half of all cases are in men between the ages of 20 and 34.
