On the Air by Laura Nachman Bucks County Courier Times April 20, 2004 "Action News" viewers learned on the Tuesday 6 p.m. news that WPVI sports director Gary Papa has prostate cancer.  Viewers got their first sign that there was something different about Papa, when after the first block of news, the camera cut to news anchor Jim Gardner, weather anchor Dave Roberts, and Papa with what looked like a shaved head. After the commercial break, the three anchors were sitting at the desk, and Gardner announced "We have some family business to discuss."  Gardner went on to explain that Papa was undergoing treatment for prostate cancer. Papa, who has been with "Action News" since 1981 said that he was diagnosed in August and has begun chemotherapy treatment, which led to the loss of his hair. "Besides this, I feel like I'm in the best shape of my life," Papa said.  With his voice cracking, Papa praised Gardner and Roberts.  He added that he began at WPVI almost 23 years ago to this day, April 15th, 1981, and intends to work another 23 years there. After returning from a break,  Papa gave a sports report.  He introduced Scott Palmer, who interviewed Phillies general manager Ed Wade at Citizens Bank Park.  After the interview, Wade gave his best wishes to Papa, and Palmer threw it back to "his good friend" Papa.  Papa finished the sportscast as Gardner joked that Papa now looked like St. Joe's head basketball coach Phil Martelli's son.  Papa, who is married and has two children will continue to work while receiving treatments.
