Newman claims to be'doing nicely'
His comments were in response to reports on numerous US TV stations, which claimed the actor was receiving treatment for lung cancer in New York.
According to Newman's business partner AE Hotchner, the 83-year-old had surgery "somewhere in the area of the lung" several years ago.
Speaking to the Associated Press, Hotchner said: "I know it's a form of cancer and he's dealing with it.
"He's battling," Mr Hotchner added. "He's doing all the right stuff. Paul is a fighter. He seems to be going through a good period right now."
"Everybody is hopeful. That's all we know."
Newman announced he was retiring from acting in May last year, telling US broadcaster NBC: "I'm not able to work anymore... at the level that I would want to."
