JPMorgan CEO Dimon tells staff that tests shows "no evidence" of cancer after treatment

JPMorgan CEO Jamie Dimon told the bank's staff Friday that he is clear of cancer.

The executive, who steered the bank through the perils of the Great Recession, said in July that he was battling throat cancer. He continued to work throughout his treatment, though with a reduced schedule.

A series of test conducted after the completion of his treatment showed "no evidence of cancer," Dimon said in an e-mail sent to staff. "The results are extremely positive and my prognosis remains excellent."

The monitoring of his health would continue for several years, Dimon said.

The e-mail was disclosed in a regulatory filing.
