Nelson explained: “I wanted to let my followers, radio listeners and all my Soul Nation party-people know that I’m going to be taking a little break from my work commitments.
“Some of you may already have noticed that I’ve not been on my daily Radio 2 slot this week.”
He continued: “After a routine check-up I was advised to have some follow up tests. As a result, I will be taking some further time off. As I’m sure you can appreciate with health issues, it’s important to deal with facts and not speculate.
“So I’m concentrating on getting better, being back to 100% me and to getting back behind the mic and the decks.”
Earlier this week, Nelson received a special prize at the Television and Radio Industries Club (Tric) awards, recognising his broadcasting career across radio and television.
The London-born DJ kicked off his career with the Madhatter sound system, putting on warehouse parties.
He then worked for pirate radio station Kiss FM in London, becoming a director once the station went legal.
He became known for his Soul II Soul Sunday night jam at the Africa Centre.
Working as a promotions manager at Cooltempo (EMI Records), Nelson championed acts like 90s US hip-hop group Arrested Development and Gang Starr.
His friendship with Jazzy B saw them set up a second Soul II Soul shop in London.
After 10 years with Kiss FM, he moved to Radio 1 in 1996 to present Rhythm Nation.
Two-time best DJ winner at the Mobo Awards, Nelson also went on to host the ceremony alongside Kelis and the late Lisa “Left Eye” Lopes.
Moving into television, he presented MTV’s black music shows The Lick and The Lick Chart before the BBC gave him his own shows, Trevor Nelson’s Urban Choice and The Lowdown.
As well as hosting stages at the Notting Hill Carnival for Radio 1, Nelson also released the compilation albums Pure Grooves and INCredible Sound Of Trevor Nelson.
He has also presented the MTV Europe Music Awards and the Prince’s Trust Urban Music Festival.
In 2002 he received an MBE for his contribution to the Millennium Volunteers programme.
