Samuel L Jackson has leant his support to a new fundraising campaign to raise awareness of male cancer.
The Captain America star has backed the One For The Boys campaign urging men to "get themselves checked out."
The actor tweeted a video to his millions of followers, presenting shocking statistics demonstrating the high incidence of cancer amongst men and offering the advice to see a doctor if any symptoms occur.
"Fact: 30% cent more men die of cancer than women. Whaaat? Get outta here! That's right: 30%. Why? Because they don't get themselves checked out early enough.
"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," he says in the video.
The One For The Boys campaign has teamed up with the crowd funding website MyGoodness.com to run an online raffle to raise necessary funds.
One of the prizes includes a chance to spend a day with the Hollywood actor in London for a "money can't buy" experience.
Co-founder of MyGoodness.com Nathalie Verrando said: "Hanging out with Samuel L Jackson for a day certainly constitutes a 'money-can't-buy' experience in my book." .
Co-founder Severine Balick added: "It's fantastic that someone of Samuel's status is prepared to give his valuable time for such a great cause in this way. The lucky winner will no doubt dine out on this experience for years to come!"
On Saturday Jackson tweeted a picture of himself with West Ham footballer Dylan Tombides who died of testicular cancer aged just 20.
The pair met at a cancer awareness event in London in November.
"Gone too soon Dylan Tombides. It was a pleasure to have met you. My thoughts are with your family," he wrote.
