Brian Kennedy was diagnosed with colorectal cancer three years ago and has been very vocal about his journey so far.
When he spoke on The Last Word before Christmas, he was about to undergo a gruelling nine-hour surgery.
Six months on, he is having chemo and is looking and feeling a lot better.
Speaking at Today FM's National Day of Dancing event for Dare To Care at the National Stadium this morning, Brian said: "Cancer makes room for itself in your life, so I had to adjust."
"I'm getting better all the time and my energy's great."
He spoke about the challenges of adjusting to having a colostomy bag, but explained that it doesn't need to have a negative impact on your life.
"Having a colostomy bag absolutely alters your life, but it doesn't have to be in a bad way at all. It didn't happen overnight for me, but I'm used to it now. It's keeping me alive."
Brian also had an important message for men who may be embarrassed about getting checked by their doctor.
"A lot of men find it very difficult to talk about anything below the waist, but I would say don't be afraid to lean on somebody and tell them if you're afraid. It saved my life."
