The 48-year-old found a lump under his eye which was later confirmed as cancerous.
"Cancer is a horrible word to hear. It frightens the life out of you," he said.
"I've faced the biggest and ugliest lads on the football field and been in some nasty bar brawls.
"But this is my toughest and scariest opponent yet.
"When the doctor said I had skin cancer, the first thing I thought was, 'How long have I got?' A million and one things go through your head."
"It's weighing very heavily on me all the time. It has really knocked me for six and made me reassess my life and goals," he added.
"If you spot something on your skin that doesn't feel right, like a little spot or tick, then get it checked out immediately."
