The actor, who starred as JR in the long-running series Dallas, will continue filming TNT’s revival of the soap.
“As J.R. I could get away with anything – bribery, blackmail and adultery. But I got caught by cancer,” Hagman said in a statement. “I do want everyone to know that it is a very common and treatable form of cancer. I will be receiving treatment while working on the new Dallas series.”
“I could not think of a better place to be than working on a show I love, with people I love. Besides, as we all know, you can’t keep J.R. down!” he added.
The network issued a statement in support of the veteran actor.
“Everyone at Warner Horizon Television, TNT and the entire Dallas family completely supports Larry Hagman during this time,” the statement says. “We look forward to watching Larry once again work his magic by bringing one of television’s most interesting, complex and controversial characters back to the screen in the new Dallas series.”
The 80-year-old underwent a liver transplant in 1995, after years of drinking and has since supported the National Kidney Foundation and spoke against smoking.
