Jamie Dimon, chief executive officer of JPMorgan Chase & Co., announced on Friday his doctors had found “no evidence of cancer” in his body, just five months after revealing he had been diagnosed with throat cancer. Dimon, 58, who finished treatments several months ago, gave his staff an update on his health.

“The good news is that the results came back completely clear, showing no evidence of cancer in my body,” said Dimon in a memo sent to employees on Friday, according to an email obtained by the New York Times. “While the monitoring will continue for several years, the results are extremely positive and my prognosis remains excellent.”

Following the announcement, shares of JPMorgan (NYSE:JPM), the largest U.S. bank by assets, jumped more than 2 percent to $62.75 in midday trading on the New York Stock Exchange.
