Will Smith vlogged his colonoscopy on his YouTube channel and during the check-up his doctor found a pre-cancerous polyp which was removed. Smith led viewers on a blow-by-blow account of the procedure, which took place in Miami. The "Aladdin" star shared a video on Instagram introducing his followers to his upcoming procedure. "These are my little no-slip socks, that's my gown, it opens in the back," Smith, 51, said. "My a-- is gonna be out so they can get to it easy." Both men and women are advised to undergo a colonoscopy every few years once they turn 50 as part of colorectal cancer prevention.
