Ben Durham is a personal trainer.
He's used to keeping fit and also training others to do so.
When he noticed a lump in his neck, cancer was one of the last things to cross his mind.
Ben, who lives in Stowmarket, was just 30 years old when he was diagnosed with Hodgkin Lymphoma.
Ben underwent 7 gruelling months of treatment.
But he believes his established fitness and healthy lifestyle helped him better withstand its side effects.
He continued to stay active throughout his treatment by walking and cycling.
Studies have shown that exercise during and after cancer treatment can improve fatigue and mental wellbeing, and speed up recovery time.
In January Ben will run his first race since being diagnosed with cancer.He's chosen to do a "5k your way" race in Bury St Edmunds - it's part of a series of races held across the country for anyone affected by cancer.
People taking part can walk, jog or run, with the emphasis being on exercise benefitting recovery.
Ben now supports others going through cancer treatment, using his story to promote the benefits of exercise.
