– The ex-professional wrestler known to his fans as "The Hitman" has just taken a hit of his own. Bret Hart has prostate cancer, he told fans in an Instagram post Monday, and he says he'll be having surgery within days, ESPN reports. "Mark Helprin wrote: 'We are all perfect clocks that Divinity has set to ticking when, even before birth, the heart explodes into a lifelong dance.' I've had a great lifelong dance and I'm a survivor of many hard battles. I now face my toughest battle," the 58-year-old Canadian wrote. Hart, who suffered a stroke in 2002 and says he hopes to raise cancer awareness, notes in the Instagram post, "I openly declare myself in my fight against prostate cancer. In the next few days, I will undergo surgery with the hope of defeating this nemesis once and for all. … I will wage my fearsome fight against cancer with one shield and one sword carrying my determination and my fury for life, emboldened by all the love that's kept me going this long already." (The pro wrestling world lost both Dusty Rhodes and Roddy Piper last year.)
