Hollywood icon Samuel L. Jackson is urging male fans to put their health first by fronting new campaign to raise awareness about testicular cancer. The Avengers star has teamed up with MyGoodness.com to launch a fundraising drive for male cancer charity One For The Boys, and has filmed a new video message, in which he encourages men to undergo regular medical check ups to prevent any early signs of cancer going undiagnosed. In the two-minute clip, Jackson uses his famously colourful language to call on fans to wise up and get checked, asking, "Have you got balls?" He goes on to state, "Fact: 30 per cent more men die of cancer than women. Whaaat? Get outta (sic) here! That's right: 30 per cent. Thirty motherf**king per cent. Why? Because they don't get themselves checked out early enough. They don't want to hear or talk about it, because it ain't (sic) the manly thing to do. They're too macho." He continues, "By not getting checked, you could lose those balls. Hell - you could lose your life! So boys, don't be dumb. If you've really got balls, show them to your doctor." The video was unveiled on Wednesday (16Apr14) in conjunction with a charity raffle on MyGoodness.com, where fans can enter to win a weekend in London, which will include a lunch date with Jackson. The winner will also land an invitation to join him at a fashion ball he is hosting in the U.K. on 15 June (14) to benefit One for The Boys, which Jackson became the spokesman for last year (13).
