Listen to One Direction on iHeartRadio

(Yahoo!) - Ever dreamt of a night out on the town with members of One Direction? Well Harry Styles and Liam Payne are aiming to help you make that dream come true, and they're working to fight cancer in the process.

On Monday the 1D heartthrobs announced that they're offering a night out with them in London as a reward for donating to Trekstock, a charity that works to fight cancer and educate young people about lifestyle choices that can help prevent the deadly disease.

To sweeten the pot, they've added incentives to the grand prize including a flight to London for the winner and a friend, a three-night hotel stay and money to spend in the English capital's famed shopping district, Carnaby Street.

In a video about the campaign, Payne points out that one in three people develops cancer at some point in their lives, and Styles says that 40 percent of these cases can be prevented, urging young people to get involved by donating and taking action to prevent cancer.

They teamed up with Trekstock, which not only works to fight cancer, but also teams up with celebrities in the music, fashion and art worlds to get the word out about lifestyle changes young people can take to help prevent the disease, and to organize mountain hikes and other trekking experiences for those who suffer from cancer.

In order to enter the competition, you have to make a minimum $3 donation on the Prizeo website by August 12. Those who donate $10 will receive a video from the boys thanking them, and a $25 donation gets you an exclusive campaign bracelet.

Seems like a pretty awesome way to meet the 1D boys on their home turf while doing some good in the world.
