Kostis Diagnosed with Colon Cancer

Peter Kostis, a well-known swing instructor and longtime golf analyst on CBS, has been diagnosed with colon cancer and is currently receiving treatment.

The 66-year-old, whose last on-air assignment was in May at the Wells Fargo Championship, issued the following statement:

"As many of you know, I have been absent from the last few CBS Sports golf telecasts. I fiercely try to keep my private life separate from my public life, but after hearing John Kruk talk about his testicular cancer last Sunday during the Red Sox-Yankees game, I decided to share my situation in hopes of spreading awareness of colon cancer.

"I am currently home recovering from successful surgery for colon cancer. It was detected early during a regular physical and colonoscopy. My great team of doctors in Phoenix will be putting me through preventative chemotherapy. Because of early detection the prognosis for a full recovery is excellent. I had zero symptoms or family history. I urge everyone, if you are over 50, get a regular colonoscopy exam whether you think you need one or not.

"I thank all of you who have sent messages, thoughts and prayers for a speedy recovery. I also want to thank my CBS Sports family, CBS management, the whole golf crew, and announcers have been fantastic in their support. I'll be back as soon as humanly possible. In the meantime, please get checked out!

Thank you, Peter."

Kostis has been with CBS since 1992,. He's the golf instructor for Paul Casey, Bernhard Langer and Steve Elkington, among other players.
