Former Buffalo Bills Hall of Fame quarterback Jim Kelly, who celebrated his 55th birthday on Saturday, feels blessed after a public battle with cancer last year.

“I’m blessed, a lot better off than a lot of other people, put it that way. I’m not here to complain, because I’m enjoying myself, that’s what you are supposed to do, have fun,” Kelly told the Rochester Democrat and Chronicle.

Around this time last year, Kelly was preparing for a battery of chemotherapy and radiation treatments on his cancer that had returned and spread.

Kelly was first diagnosed with squamous cell carcinoma in 2013. A portion of his jaw was removed at that time.

Kelly announced in September that he was cancer-free, but then he got a staph infection in his bones. He had to undergo an eight-week treatment for the methicillin-resistant Staphylococcus aureus (MRSA) infection.

Kelly admits he battles daily pain, but he’s not complaining. Just three weeks ago, Kelly had another MRI that confirmed he is still cancer free.

“They found no cancer, thank God, but there are other issues,” Kelly said. “It’s like always, you go to a doctor and they tell you the great news and follow up with a ‘but.’ No, I said, no more ‘buts’ … I’m sick of ‘buts’!”

Kelly thinks less about his own health problems than about his son Hunter, who died in 2005 at the age of 8. Valentine’s Day was Kelly’s birthday, one that he shares with Hunter.

“What’s sometimes hard for me is to see the joy my daughters have spending quality time with their mother,” Kelly said. “I know I’m missing out on that from the father-and-son standpoint. I love my daughters to death, but not like having a son. You dream about what could have been. And then I realize, even through his suffering, he’s made me the man I am today.”
