Singer Enrique Iglesias is using his world tour to help save lives by setting up health stands to promote the need for bone marrow donations.

Bosses behind the organisation Love Hope Strength (Lhs) will be at the I Like It hitmaker's gigs to scan willing concertgoers in order to help match bone cancer patients with suitable volunteers for the National Marrow Registry.

He tells, "When you go up on stage and you look at my fans, it's so diverse ethnically, and I thought it would be perfect. I thought we would get people of different races to be able to register for this organisation, and I thought that would really help... We've got to register as many people as possible... There's a lot of people out there, a lot of kids, that need this."

Lhs executive director Shannon Henn is grateful for the Spanish superstar's support as the system is lacking in ethnic donors.

She says, "Only 10 per cent of the overall national marrow registry is made up of Hispanic population. So when you're Hispanic looking for a transplant, your chances of finding a match significantly decrease due to the lack of that population on the registry.

"So by reaching out to a community through someone like Enrique Iglesias, who has such an incredible Hispanic following, we're able to register people to the database that we never could before."
