He added he will be treated for the condition on September 14.
A keen runner who took part in the London Marathon earlier this year, Evans went on to say he will be unable to run for a month following treatment.
“I can’t run for a month afterwards so I’m going to do nothing but run until then. Is that okay?” he said.
The diagnosis comes four years after Evans had a cancer scare when he discovered marks on his body.
In 2019, the UK had experienced a hot summer which Evans explained meant “high levels of UV” sparked concern over the markings.
Speaking about his scare, he said: “I went and had a few marks on my body inspected by a skin expert before Christmas and she said, ‘You need to come and see me again, just because of your complexion’.”
Although he was not diagnosed with skin cancer on that occasion, Evans said he would get his skin checked once a year.
