Married at First Sight husband Nic Jovanovic has revealed he is battling cancer for a second time.

The 28-year-old was diagnosed with testicular cancer four years ago but managed to beat the disease after intense treatment.

But in December 2018, Jovanovic discovered a "semi-hard lump" on one of his testicles which prompted him to seek medical advice.

The doctor then diagnosed the MAFS star with cancer for a second time.

Jovanovic said he was devastated after working so hard to become fit and healthy following his first diagnosis in 2014.

"I couldn't believe it. Four years later... there was so much going on in my life, for it to come back, I'm still in shock that it came back," he told 9Honey.

"I was fit, I train, I eat well, I don't do drugs, I hardly drink. I was the epitome of healthy.

"How does it come back? Why? What have I done to deserve this? What have I done? What am I doing wrong?" he recalled asking himself.

The 28-year-old revealed he delayed undergoing surgery so he could film scenes for MAFS.

The MAFS husband is now cancer free as of January thanks to surgery and chemotherapy.

Testicular cancer has a high survival rate with 98 per cent success for the first diagnosis and 96 per cent if the cancer returns.
