City Council Chairman Jack Benson said Monday he has been diagnosed with squamous cell carcinoma, a type of skin cancer that can be far less lethal than its cousin melanoma.

"It is not melanoma," Mr. Benson said. "The doctor said it would not kill me."

Mr. Benson, who was elected chairman of the Chattanooga City Council two months ago, said he found last week the skin cancer had spread to his lymph nodes and would require surgery. But he said it would be outpatient surgery and he expects to miss only about half a day from his duties as chairman.

"It's the same thing John McCain had," Mr. Benson said.

He will be able to maintain his council hours and responsibilities, he said.

The American Cancer Society reports that more than 1 million people a year are diagnosed with non-melanoma skin cancer. In 2007, there were 2,740 deaths reported nationwide from such cancers, according to the society.

Councilman Manny Rico said Monday he still has concerns, even if Mr. Benson's cancer is not the more deadly melanoma.

"You can't help to worry," he said. "We need Jack. He's our senior leader in there.

"Hopefully, he'll just have a little surgery and it will all be over," Mr. Rico said.
