Houston Texans owner Bob McNair is healthy and cancer-free after undergoing an aggressive therapy regimen for more than 10 months.

"I didn't think I was going to die. I knew some did," McNair told the Houston Chronicle. "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, 77, established his wealth as chairman of Cogen Technologies and was instrumental in bringing football back to Houston with the Texans' inaugural season in 2002 and a Super Bowl to newly constructed Reliant Stadium two years later.

McNair said he was diagnosed six years ago with chronic lymphocytic leukemia, a type of cancer of the blood that spreads more deliberately than other types of the disease. McNair's condition changed last October when treatments for a form of skin cancer did not slow the spread of the disease.

At that time, he opted for chemotherapy and proton therapy, an aggressive form of treatment which delivers more powerful, isolated doses.

McNair said he suffered second-degree burns on his face and needed plastic surgery, but was declared healthy in May.

A subsequent checkup on Monday showed no traces of cancer.

In order to keep a low profile, McNair underwent his radiation treatment under an assumed name and was given a key to the medical center's back door.
