British singer Antony Costa is throwing his support behind a campaign to raise money for a pal's life-saving cancer treatment.

The Blue star is urging fans to donate to Heroes for Helen, a funding website set up by Helen Koumianakis, a 32 year old friend of Costa's who was diagnosed with brain cancer two years ago.

Koumianakis is hoping to raise $216,000 (£135,000) to pay for breakthrough treatment in the U.S.

Costa has posted a link to the donation site on, adding, "Help raise awareness."

The appeal has already garnered almost $48,000 (£30,000).
