Houston Texans owner Bob McNair has successfully battled two forms of cancer, and told the Houston Chronicle he now has a clean bill of health.

He underwent experimental treatment for chronic lymphocytic leukemia (CLL), painful surgery on the left side of his head and neck and 30 sessions of radiation, causing second-degree burns that required a plastic surgeon to perform skin grafts.

"I've never been through anything like that, but two days ago, I was given a clean bill of health, so it was worth the pain and suffering," McNair, 77, said Wednesday.. "I didn't think I was going to die. I knew some did. I knew there were some rumors. That's one of the reasons I'm talking about it. I don't want people to think it's something it's not. I'm not ill. I'm healthy. I'm not going anywhere. We've got Super Bowls to win."

McNair said the radiation treatment was painful.

"The radiation was worse by far," McNair said. "I had bandages all over my head. I looked like a mummy. On the side of my head and neck and down to my collarbone, I had second-degree burns. My skin blistered and peeled before it grew back. That was the worst part of it. The first three weeks was a cakewalk, but then it got pretty severe."

McNair has battled skin cancer for more than 20 years.

"It wasn't too long ago when you mentioned cancer, and people thought it was a death sentence, but I want people to know that's not the case," McNair said. "They have cures for certain forms of cancer, and there are some they're working on. If they get treatment early and listen to their doctor and follow their advice, they can get the same results and be cured. Don't be discouraged. Attack it. It's not going to be pleasant, but the battle can be won."
