(Updated with additional information from AIG's press release.)
NEW YORK (TheStreet) -- American International Group (AIG) - Get Report announced late Monday that its chief executive, Robert H. Benmosche, has been diagnosed with cancer, but it appears he'll remain in his role with the company.

"The good news is that I feel fine, and I continue to work according to my normal schedule. As for my long-term prognosis -- I will have a better idea over the next couple of months of what that will look like as I continue to undergo treatment and my doctors refine their diagnosis. All that said, I remain absolutely committed to my job, to AIG, and to all of our stakeholders," Benmosche said in a prepared statement.

Benmosche, 66, has served as AIG's president, CEO and director since August 2009. Prior to that he served as chairman and CEO of MetLife.

AIG said Benmosche is "undergoing aggressive chemotherapy" but did not specify the type of cancer its CEO suffers from.

Chairman Robert S. Miller, speaking for AIG's board, said "we have every confidence that we will all continue to work together smoothly and without interruption as AIG executes its

repayment roadmap," indicating Benmosche will remain in his role with the insurer as he undergoes treatment.

"At the same time," Miller added, "we will make sure that we engage in appropriate contingency planning to ensure management continuity."
