Luke Humphries is aiming to hit the bullseye for Prostate Cancer UK during his bid to win the Paddy Power World Darts Championship.
The world number three faces Scott Williams in Tuesday night's semi-finals at London's Alexandra Palace, and is two matches away from winning the sport's biggest title.
The 28-year-old is supporting event's charity partner, Prostate Cancer UK, throughout the World Championship, with THE BIG 180 partnership seeing Paddy Power and the PDC link up with the men's health charity.
However, he has now revealed his personal motivation to land even more 180s in the event to raise funds for the charity and urged men to use Prostate Cancer UK's simple online risk-checker at prostatecanceruk.org/180risk.
"THE BIG 180 is an amazing charity campaign and what Paddy Power and Prostate Cancer UK are doing is fantastic," said Humphries.
"It would be amazing if we can get to a £1 million donation and I'll be doing everything I can to help - it means a lot to me.
"My girlfriend's dad had a scare recently. He was very, very lucky; he was honest about it and wants to share his story about how lucky he was.
"He caught it in time. These things need awareness raised and I urge men to check their risk."
Humphries has hit the third most 180s so far in the event with 36, including 12 in his epic fourth round win over Joe Cullen and a further dozen in Monday's quarter-final defeat of Dave Chisnall.
Paddy Power are donating £1,000 to Prostate Cancer UK for every 180 hit during the tournament - with £832,000 already being pledged to the charity.
Over 60,000 men have been identified as high-risk through the online risk-checker since THE BIG 180 was launched.
