His treatment for Hogkin's lymphoma continues after he was originally misdiagnosed by medics who thought he was suffering from a persistent bug.

Campbell tells 93.3 WMMR: "I remember getting this head cold and flu-like symptoms, and a doctor gave me some antibiotics. Five or six weeks later I had the same thing come back, and the one thing that was constant was this cough that wouldn't go away.

"My doctor said, 'Sometimes it takes time for these things to heal up.' A respiratory doctor gave me an inhaler and nasal spray. I said, 'This isn't really getting any better,' and he'd just give me a stronger inhaler."

After a year he insisted on an X-ray, which identified there was a more serious problem. "A very brilliant doctor said she was pretty sure I had Hodgkin's lymphoma," Campbell recalls. "We did a biopsy a couple of days later, and there you go - Hodgkin's lymphoma."
