The fight against cancer was given a big push this weekend at the third annual Knock Out Cancer event held at the Galleria in Mt. Lebanon. On the evening of Nov. 10, hundreds of men and women from all over the region gathered at the mall to support four cancer-fighting charities: the Young Women’s Breast Cancer Awareness Foundation, the Obediah Cole Foundation for Prostate Cancer, The National Ovarian Cancer Coalition and the Pancreatic Cancer Action Network. Joining the fight was guest host Bret Michaels, who is originally from Butler. The Poison frontman was the winner of “The Celebrity Apprentice” in 2010 and competed again in 2013, both times playing for charities that benefit diabetes research.
