Goldman Sachs CEO and Chairman Blankfein says he has form of lymphoma that's 'highly curable'

The CEO and chairman of Goldman Sachs says that he has a form of lymphoma that is "highly curable."

Lloyd Blankfein said in a post on the firm's website Tuesday that he underwent a series of tests after not feeling well for several weeks. The executive said that he'll receive chemotherapy in New York over the next several months as part of his treatment plan.

He wrote that "My doctors' and my own expectation is that I will be cured."

Blankfein, who's also known for his philanthropy, said he'll reduce travel during treatment but will be able to "work substantially as normal."

Blankfein said he's discussed his planned work approach with the Goldman Sachs board and that they are supportive.

Shares of the New York-based company fell slightly in premarket trading.
