Chris Anderson, 26, a former Dunfermline and Berwick Rangers striker, said he was lucky the disease was spotted as he had been ignoring the warning signs.
It was only the intervention of a team-mate at his current club, Edinburgh-based Lowland League outfit Spartans, that forced him to seek medical help.
Mr Anderson had an "uncomfortable" feeling around his groin area during the festive period last year.
Aches and pains in his back had also emerged and a small lump had formed in one of his testicles.
But it was only after a friendly between Spartans and Hibs at the start of January that he was ordered to visit the doctors.
He said: "I felt aches and pains and also the lump but being a guy I thought it would just go away. I was fit and, I thought, healthy, so I didn't think too much about it all."
Spartans have their own team doctor and one of the players, Jonny Seeley, is also a doctor.
Mr Anderson said: "After the Hibs game I told them both I was not feeling well and I also mentioned the lump. They sent me straight away to get checked - I hate to think what would have happened if they hadn't."
After initial tests in Edinburgh the former Gala Fairydean and Selkirk striker was given a priority appointment at Borders General Hospital. A scan and further tests revealed his worst fears - the lump was cancerous.
He said: "If the doctors at Spartans hadn't been there I know I would have continued trying to play football and trying to take my mind off how I was feeling.
"The doctors at the hospital were quick to tell me that the longer you leave these things the worse they get. Thankfully the cancer hadn't spread elsewhere."
There are around 2000 new cases of testicular cancer detected in the UK every year, almost double the amount as in 1975.
In 1999 Celtic defender Alan Stubbs was diagnosed with testicular cancer but made a full recovery and resumed his career.
The disease leads to around 70 deaths every year when not detected early enough.
Mr Anderson underwent an operation to remove his cancer at the start of February.
Despite the soreness and tiredness that goes with any post-operation recovery he was given the all-clear during follow-up scans. Check-ups over the past eight months have all brought good news as well.
But the player is not taking anything for granted. He said: "I am told there is an 85% chance that cancer won't return and I can only hope it doesn't.
"You need a bit of time to come to terms with what has happened but football has given me a focus. I was back training in the gym a couple of months after the operation and I'm only now getting close to the match fitness I had before being diagnosed.
"There's no getting away from it, I got a fright and it helps you put everything into perspective."
Testicular cancer is the most common form of cancer in young men, but doctors rate survival at around 97% with the proper treatment.
Mr Anderson came off the bench to help Spartans lift the King Cup at the end of May.
Throughout the summer he has worked on his own fitness as well as kick-starting a coaching and fitness enterprise with his friend Gerry Rossi in their home town of Peebles.
The one lesson he is keen to relay to everyone is about checking for the signs of cancer.
He added: "My advice would be, don't be embarrassed about it. If you notice a lump, it probably won't just go away. Get checked out immediately."
Regular self-examination is advised and any abnormalities can be spotted early on.
Signs of testicular cancer include a lump in either testicle, enlargement of one testicle, a feeling of heaviness in the scrotum and a dull ache in the abdomen or groin.
