MARRIED At First Sight Australia's Nic Jovanovic discovered his testicular cancer had returned while filming the reality show in early 2019.
The 29-year-old kept the news from wife Cyrell Paule and was forced to undergo chemotherapy and have a teste removed as the show then aired on TV in Australia.
He was first diagnosed with testicular cancer when he was 24, and said battling the deadly disease prevented him trying to find love.
During an interview with The Sun Online, Nic says that having his season now airing in the UK has brought back some emotional memories.
“It's bringing back a lot of memories of when it aired here - some better than others! It was such a huge blow for me when I found out I had been diagnosed with testicular cancer for a second time,” he said.
“We were currently filming the final dinner party and it was a weird feeling, knowing that in the next few days I was going in for surgery to finally beat it.
“I decided not to bring it up to anyone on the show and didn't want to discuss it with any of the guys at the dinner party because I didn't want anyone to stress about me and what I was about to go through.”
Nic now works with charities such as The Cancer Council and Movember Foundation to help encourage guys to “not put things off and to make sure if you feel something is off, go and get checked”.

Reflecting on how life has changed since filming, Nic says his “health is great now” and he learned a lot about himself by watching the show back.
“I feel I have grown so much as a person since then. I have been able to watch the season and see how I used to handle situations – and now I am better for it and will take on everything I learnt throughout my experience.
“I always tried to put Cyrell first and gave the experiment my all. It was such a huge commitment and I knew it was going to be huge part of my life. I did not want any regrets and I didn't want to miss the opportunity to find love.”
